Abstract (sommario):

Acremonium is known to be regularly isolated from food and also to be a cause of human disease. Herein, we resolve some sources of confusion that have strongly hampered the accurate interpretation of these and other isolations. The recently designated type species of the genus Acremonium, A. alternatum, is known only from a single isolate, but it is the closest known relative of what may be one of the planet’s most successful organisms, Acremonium sclerotigenum/egyptianum, shown herein to be best called by its earliest valid name, A. egyptiacum. The sequencing of ribosomal internal transcribed spacer (ITS) regions, actin genes, or both for 72 study isolates within this group allowed the full range of morphotypes and ITS barcode types to be elucidated, along with information on temperature tolerance and habitat. The results showed that nomenclatural confusion and frequent misidentifications facilitated by morphotaxonomy, along with misidentified early sequence deposits, have obscured the reality that this species is, in many ways, the definitive match of the historical concept of Acremonium: a pale orange or dull greenish-coloured monophialidic hyphomycete, forming cylindrical, ellipsoidal, or obovoid conidia in sticky heads or obovoid conidia in dry chains, and acting ecologically as a soil organism, marine organism, plant pathogen, plant endophyte, probable insect pathogen, human opportunistic pathogen, food contaminant, probable dermatological communicable disease agent, and heat-tolerant spoilage organism. Industrially, it is already in exploratory use as a producer of the antibiotic ascofuranone, active against trypanosomes, cryptosporidia, and microsporidia, and additional applications are in development. The genus-level clarification of the phylogeny of A. egyptiacum shows other historic acremonia belong to separate genera, and two are here described, Parasarocladium for the Acremonium radiatum complex and Kiflimonium for the Acremonium curvulum complex.

Abstract (sommario):

Various natural interactions exist between fungi and plants, including mutualism and pathogenesis. This study evaluated the interaction of fungi Acremonium sp. to plants and pathogenic fungi. Acremonium sp. was isolated from the root tissue of an oil palm plant using surface sterilization methods before isolation. The potential pathogenicity interaction of Acremonium sp. was assayed towards Chinese white cabbage (Brassica rapa L. var. pekinensis) in vitro. Based on the PDA medium assay, isolated Acremonium sp. exhibited pathogenic traits against Chinese white cabbage within 14 days post-inoculation. Interestingly, Acremonium sp. showed antifungal activity against Fusarium oxysporum IPBCC.19.1468, with an average inhibition rate of 69.11%. Our data suggest the pathogenicity interaction of Acremonium sp. toward cabbage plant and fungi F. oxysporum IPBCC.19.1468.

Abstract (sommario):

Corneal infections may be caused by bacteria, viruses, fungi or protozoa. Fungal keratitis, usually associated with Fusarium, Candida and Aspergillus, develops from a saprophytic fungal infection as well, one of the agent being Acremonium sp. Acremonium infection occurs when a patient is suffering from a penetrating injury, common in ophthalmic patients. Symptoms of Acremonium- induced keratomycosis are similar to the usual presentation of a fungal infection – patients complain of decreased visual acuity, ocular pain, redness of the eye, floaters and corneal opacity. While there is no established method of treatment for Acremonium keratitis, usual antimycotics and antibiotics intended for keratomycosis are used – fluoroquinolones, azoles and polyenes. If pharmacotherapy does not yield favorable outcomes, surgical forms of treatment should be introduced, such as keratoplasty. If surgical methods are ineffective in infection control, an end-stage solution – enucleation is employed. Although Acremonium is an opportunistic fungal pathogen, the infection is generally effectively treated using pharmacotherapy.

Abstract (sommario):

Acremonium and the recently separated acremonium-like genera, such as Sarocladium, are emerging causes of opportunistic disease in humans, mainly post-traumatic infections in immunocompetent hosts, but also invasive infections in immunocompromised patients, such as those undergoing transplantation. Acremonium egyptiacum has emerged as the major pathogenic Acremonium species in humans, implicated mainly in nail but also in disseminated and organ specific infections. In this first study of acremonium-like clinical isolates in Greece, 34 isolates were identified and typed by sequencing the internal transcribed spacer, and their antifungal susceptibility was determined by a modified CLSI standard M38 3rd Edition method for filamentous fungi. A. egyptiacum was the primary species (18 isolates) followed by Sarocladium kiliense (8), Acremonium charticola, Gliomastix polychroma, Proxiovicillium blochii, Sarocladium terricola, Sarocladium zeae, and Stanjemonium dichromosporum (all with one isolate). Two isolates, each with a novel ITS sequence, possibly represent undescribed species with an affinity to Emericellopsis. All three A. egyptiacum ITS barcode types described to date were identified, with 3 being the major type. Flutrimazole, lanoconazole, and luliconazole presented the lower minimum inhibitory concentration (MIC) values against A. egyptiacum, with a geometric mean (GM) MIC of 2.50, 1.92, and 1.57 μg/mL, respectively. Amphotericin B, itraconazole, posaconazole, voriconazole, terbinafine, amorolfine, and griseofulvin MICs were overall high (GM 12.79–29.49 μg/mL). An analysis of variance performed on absolute values showed that flutrimazole, lanoconazole, and luliconazole were equivalent and notably lower than those of all the other drugs tested against A. egyptiacum. Antifungal susceptibility of the three different A. egyptiacum genotypes was homogeneous. Overall, the high MICs recorded for all systemically administered drugs, and for some topical antifungals against the tested A. egyptiacum and other acremonium-like clinical isolates, justify the routine susceptibility testing of clinical isolates.

Microrganismos foram isolados de areia fenólica resultante de atividades metalúrgicas, utilizando meio mínimo para fungos e pentaclorofenol (PCF) como única fonte de carbono. Após quatro repiques sucessivos em intervalos de 15 dias de incubação, as culturas foram plaqueadas em meio de Martin. Três gêneros de fungos foram isolados e identificados como Acremonium sp., Paecilomyces sp. e Penicillium sp. Estes foram testados para degradar os corantes índigo e RBBR (Azul Brilhante de Remazol - R) e o organoclorado PCF. A descoloração do índigo foi de 99%, para Paecilomyces e Penicillium, e de 74%, para Acremonium, e a de RBBR foi de 16%, para Penicillium; 14%, para Acremonium, e 5%, para Paecilomyces. Usando azul de bromotimol como indicador de degradação de PCF, foram obtidos 24% de descoloração para Acremonium; 22%, para Penicillium, e 17%, para Paecilomyces Utilizando cromatografia gasosa, detectou-se degradação de PCF de 69%, para Penicillium; 65%, para Paecilomyces, e 40% para Acremonium, respectivamente. Os resultados mostraram que foi possível isolar microrganismos de uma areia de fundição, altamente contaminada com fenóis, e os fungos isolados foram capazes de degradar PCF e outros xenobióticos testados.

Abstract (sommario):

Introduction: It is a rare case of continuous ambulatory peritoneal dialysis-related peritonitis associated with Acremonium sp. infection. Case presentation: Symptoms of Acremonium infection peritonitis are hidden and atypical, leucocytes in ascites are moderately elevated, and general bacterial culture difficulty obtains positive results. In this report, a patient with peritoneal dialysis-related peritonitis caused by Acremonium species was successfully treated without catheter removal in our hospital. The organism species was cultured from a catheter and PD effluent fluid. The patient’s peritonitis did not relapse within 6 months. Conclusions: Once a patient on peritoneal dialysis was infected with fungal peritonitis, the outcome was usually to remove the tube and stop peritoneal dialysis. In this case, our experience is that using a catheter-salvage therapy method, we can successfully cure PD-related peritonitis associated with Acremonium sp.

Abstract (sommario):

<em>Acremonium</em> is acknowledged as a highly ubiquitous genus including saprobic, parasitic, or endophytic fungi that inhabit a variety of environments. Species of this genus are extensively exploited in industrial, commercial, pharmaceutical, and biocontrol applications, and proved to be a rich source of novel and bioactive secondary metabolites. <em>Acremonium</em> has been recognised as a taxonomically difficult group of ascomycetes, due to the reduced and high plasticity of morphological characters, wide ecological distribution and substrate range. Recent advances in molecular phylogenies, revealed that <em>Acremonium</em> is highly polyphyletic and members of Acremonium s. lat. belong to at least three distinct orders of Sordariomycetes, of which numerous orders, families and genera with acremonium-like morphs remain undefined. To infer the phylogenetic relationships and establish a natural classification for acremonium-like taxa, systematic analyses were conducted based on a large number of cultures with a global distribution and varied substrates. A total of 633 cultures with acremonium-like morphology, including 261 ex-type cultures from 89 countries and a variety of substrates including soil, plants, fungi, humans, insects, air, and water were examined. An overview phylogenetic tree based on three loci (ITS, LSU, <em>rpb2)</em> was generated to delimit the orders and families. Separate trees based on a combined analysis of four loci (ITS, LSU, <em>rpb2,</em> <em>tef-1α</em>) were used to delimit species at generic and family levels. Combined with the morphological features, host associations and ecological analyses, acremonium-like species evaluated in the present study are currently assigned to 63 genera, and 14 families in <em>Cephalothecales, Glomerellales</em> and <em>Hypocreales,</em> mainly in the families <em>Bionectriaceae, Plectosphaerellaceae</em> and <em>Sarocladiaceae</em> and five new hypocrealean families, namely <em>Chrysonectriaceae, Neoacremoniaceae, Nothoacremoniaceae, Pseudoniessliaceae</em> and <em>Valsonectriaceae.</em> Among them, 17 new genera and 63 new combinations are proposed, with descriptions of 65 new species. Furthermore, one epitype and one neotype are designated to stabilise the taxonomy and use of older names. Results of this study demonstrated that most species of <em>Acremonium</em> <em>s. lat.</em> grouped in genera of <em>Bionectriaceae,</em> including the type <em>A. alternatum</em>. A phylogenetic backbone tree is provided for <em>Bionectriaceae,</em> in which 183 species are recognised and 39 well-supported genera are resolved, including 10 new genera. Additionally, <em>rpb2</em> and <em>tef-1α </em>are proposed as potential DNA barcodes for the identification of taxa in <em>Bionectriaceae.</em>

Abstract (sommario):

Acremonium arthrinii sp. nov. was collected from Phyllostachys heteroclada in the forest of Sichuan Province, China. This mycopathogenic fungus was frequently found on the top of the ascomata of Arthrinium yunnanum, and presumably causes its death. In this study, the new species was examined morphologically and maximum likelihood and Bayesian analyses of a combined LSU, SSU, ITS and TEF 1-α were performed to clarify the taxonomic affinity of the species. Acremonium arthrinii can be distinguished from other Acremonium species based on conidiogenesis, size differences in conidiophores, conidiogenous cells and conidia, and its DNA sequence differences and phylogeny. Detailed descriptions, micrographs and phylogenetic relationships of the new taxon were provided.

Abstract (sommario):

Aquilaria crassna is one of the Aquilaria species that could produce agarwood. agarwood production of A. crassna can be induced by microfungi as an inoculant. Ecological interaction between the host plant, wounding and inoculant in the formation of agarwood has not yet clearly. other factors like the plant ages, plant species, environ- ment also played important roles in the formation of agarwood. This research aimed to determine the influence of the combination between planting media and Acremonium sp. and Fusarium sp. to agarwood quality of Aquilaria crassna. The experiment was consisted of two factors, which were five planting media and two inoculants fungi i.e. Acremonium sp. and Fusarium sp. The observed parameters were the percentage of senescence leaves, color of wood, level of fragrant and terpenoid content. The best agarwood fragrant was produced by the seedlings that were treated with either combination of husk charcoal media enriched with NPK fertilizer and Acremonium sp. or the combina- tion between husk charcoal media enriched with Hoagland modified solution and Fusarium sp.. The darkest color of wood was produced by the seedlings that were treated with combination of husk charcoal media enriched with NPK fertilizer and Acremonium sp., as well as for the same media with Fusarium sp.. during the experiment terpenoid could not be detected from the treated seedlings. Acremonium sp. caused more leave senescence than that of Fusarium sp..

Testo completo

Abstract (sommario):

To determine the potential for intra-oviductal contamination of sea turtle eggs with fungi accumulated during nesting, turtles were sampled for cloacal fungi. Pre-gravid females had a low incidence (17%) of cloacal fungi (Acremonium, Cladosporium, Penicillium). A higher occurrence (30%) of these same fungi in courting animals, that had not bred for ≥2 years, was probably the result of transfer during intromission. Nesting (75%) and inter-nesting (100%) turtles had the greatest occurrence and diversity of cloacal fungi (Acremonium, Aspergillus, Chrysosporium, Fusarium, Mucor, Penicillium, Phialophora, Sporothrix, Stachybotrys). The incidence of cloacal fungi rapidly decreased after nesting, to 28% within one year (Acremonium, Penicillium) and 13% in animals that bred at least two years earlier (Acremonium, Cladosporium, Penicillium). The other species of fungi are probably lost during defaecation.If fungal spores can be transported and maintained in the sea turtle oviduct by the same mechanisms as for spermatozoa, acute intra-seasonal contamination of eggs by fungi may be possible. The potential for chronic inter-seasonal contamination of the oviduct appears to be low.

Arab Journal of Plant Protection, 41(2): 140-145. https://doi.org/10.22268/AJPP-41.2.140145 Ultrastructure and physiological effects of the biological control agent Acremonium sp. on larvae of the spiny bollworm (SBW) Earias insulana (Boisduval) (Lepidoptera: Noctuidae) were investigated. The isolate of Acremonium sp., EZ1 (MN25101) was applied on the 4 th instar larvae and pupae of the spiny bollworm E. insulana, with two ml spore suspension of different concentrations of 6x106 , 6x107 and 6x108 spores/ml mixed with four gm of artificial diet. Scanning electron microscopy (SEM) was used to investigate sporulation potential and the extent of damage to the growth rate of Acremonium sp. on the exoskeleton of E. insulana larvae and pupae five days after inoculation, as compared to the untreated control. Treated larvae showed varied level of cuticle damage. Surface of infected pupae showed varied stages of mycelial growth. The biochemical parameters investigated were: carbohydrate hydrolyzing enzymes activity (trehalas, invertase, and amylase), the total soluble protein, acetyl choline esterase, aspartate aminotransferase (AST) and Alanine aminotransferase (ALT) activities. High significant reduction in amylase, trehalase and ALT activities in treated larvae was observed. On the other hand, high significant gradual increase in the amount of total soluble protein and the acetyl choline esterase activity were observed. At the same time AST activity was slightly increased, whereas invertase activity was not significantly different from the control. Scanning electron microscopy clearly showed the ability of Acremonium sp. fungus to damage the cuticle of both larvae and pupae of E. insulana by spore's germination. In addition, it disturbed the activity of many important enzymes, thus it can play a vital role in the control of the target pest in a safe manner without polluting the environment. Keywords: Earias insulana, Acremonium sp., scanning electron microscopy, AST, ALT.

Abstract (sommario):

The fungus Acremonium strictum was isolated from rye grass, kikuyu and another species of Pennisetum. Two isolates of A. strictum significantly inhibited, in vitro, the rate of growth of five fungi commonly associated with grasses. Extracts from cultures of the isolates also inhibited the rate of hyphal elongation. From the evidence, these isolates of Acremonium are classified as endophytes and their relationship with the 'Balansioid' endophytes must be reconsidered.

Abstract (sommario):

Fungal diseases cause signifi cant damage to agriculture. Plectosphaerella melonis (syn. Acremonium cucurbitacearum and Nodulisporium melonis) is a pathogen of cultivated plant diseases in Spain, Italy, Japan, USA, Egypt, and Ukraine. This review discusses the main results of research related to this phytopathogen. By morphological and cultural features, P. melonis is a morphologically intermediate species between A. strictum and A. charticola, however, 5.8S-ITS regionbased phylogenetic analysis showed that P. melonis is a monophyletic taxon more closely related to Plectosphaerella than to other species of the genus Acremonium. The most susceptible plants are at the stage of germination; however, the development of the disease is manifested in the fruiting period. For a comprehensive assessment of virulence, real leaf area (RLA) of the first two leaves, lesion of hypocotyl (RH), root collar (RSR), primary (R1R) and secondary roots (R2R) are measured. P. melonis affects the root system, in particular the root collar and hypocotyl, and colonizes the epidermis and cortex of the root centrographically towards the stem. The range of host plants includes Cucurbitaceae, however, peppers, tomatoes, basil, and parsley are infected as well. Plants vary in susceptibility depending on the species and even variety. The pathogenic response of plants differs depending on the growing conditions (protected and open soil), the interaction between the pathogen and competing microorganisms, and other ecological and trophic relationships. The main means of control are the use of long-term crop rotations and the selection of resistant varieties. In Ukraine, a strain of the antagonist fungus Trichoderma viride was selected, which is an effective means for controlling P. melonis 502. The aim of our work was to establish the role of P. melonis in the development of diseases of cultivated plants.

Abstract (sommario):

The ability of Acremonium sp. 502 phytopathogenic fungi to produce ethylene was studied.It was found that Acremonium sp. 502 is able tosynthesize ethylene. The highest level of biosynthesis was recorded after 5 weeks of cultivationthat coincides with the terms of the highest levelof synthesis of cellulases that are involved in thepenetration of the fungus into the plant. A suggestion that ethylene synthesis plays a certainrole in the mechanism of pathogenesis of cucumbers plants is offered.

Abstract (sommario):

Acremonium is a polyphyletic genus known as cephalosporium formerly widely spread in environment commonly found in soil, decaying vegetation, plant debris and decaying food. Acremonium sclerotigenum isolated from clinical samples of tinea infected patients from Punjab Pakistan. Goal of the study is to achieve biochemical characterization of the A.sclerotigenum and to analyze the effect of physiological stress and terbinafine susceptibility in test strain. A.sclerotigenum was analyzed for oxidative, osmotic stress adaptability by culture characteristics, protease and lipase qualitative and activity assays and antifungal terbinafine susceptibility testing for isolated Acremonium strain. Study revealed that A.sclerotigenum is not resistant to osmotic and oxidative stress. Level of extracellular proteolytic enzymes is low although lipase enzyme found to be active at a moderate level. A.sclerotigenum has very low MIC for terbinafine. A detailed research on the mechanism involving in anti-fungal resistance in A.sclerotigenum, is still to be explore.

Abstract (sommario):

Fifteen isolates of fungal endophytes of grasses were studied for their ability to metabolize different sources of carbon and nitrogen. These endophytes had been isolated from 12 different species of Poaceae and included Clavicipitaceae with or without a teleomorph (genera Epichloë and Neotyphodium, respectively) and species belonging to the genus Acremonium sensu stricto (Acremonium chilense-like). Pectin and cellulose as carbon sources and tryptophan and methionine as nitrogen sources appeared to support poorly the growth of most isolates. Hexoses, disaccharides, complex nitrogen sources, asparagine, and glutamine supported growth of all isolates. The isolates of genus Neotyphodium were characterized by limited growth whatever the substrate, the inhibition of their growth by high concentrations of glucose and fructose, and their inability to assimilate pentoses (xylose, arabinose) and nitrates. The isolates of genus Epichloë showed better growth than those of the previous group and their growth was not inhibited by high concentrations of glucose, but they were also unable to use pentoses. The Acremonium chilense-like isolates showed rapid growth and were distinguished by their ability to use the pentoses and nitrates. In contrast, they showed relatively poor growth on methionine and alanine as nitrogen sources. They showed the most rapid growth on high concentrations of glucose or fructose.Key words: carbon sources, nitrogen sources, Neotyphodium, Epichloë, Acremonium, grass endophytes.

Abstract (sommario):

We present a case of subcutaneous hyalohyphomycosis due to Acremonium recifei, a species whose habitat is probably the soil, first identified in 1934 by Arêa Leão and Lobo in a case of podal eumycetoma with white-yellowish grains and initially named Cephalosporium recifei. A white immunocompetent female patient from the state of Bahia, Brazil, with a history of traumatic injury to the right hand is reported. The lesion was painless, with edema, inflammation and the presence of fistulae. Seropurulent secretion with the absence of grains was present. Histopathological examination of material stained with hematoxylin-eosin showed hyaline septate hyphae. A culture was positive for Acremonium recifei. Treatment with itraconazole, 200 mg/day, for two months led to a favorable course and cure of the process. We report for the first time in the literature a case of subcutaneous hyalohyphomycosis due to Acremonium recifei in a immunocompetent woman. Treatment with itraconazole 200 mg/day, for two months, resulted in cure.

Abstract (sommario):

Acremonium fungi is one of the greatest and most complex genera in Hyphomycetes, comprising 130 species of marine and terrestrial sources. The past decades have witnessed substantial chemical and biological investigations on the diverse secondary metabolites from the Acremonium species. To date, over 600 compounds with abundant chemical types as well as a wide range of bioactivities have been obtained from this genus, attracting considerable attention from chemists and pharmacologists. This review mainly summarizes the sources, chemical structures, and biological activities of 115 recently reported new compounds from the genus Acremonium from December 2016 to September 2023. They are structurally classified into terpenoids (42%), peptides (29%), polyketides (20%), and others (9%), among which marine sources are predominant (68%). Notably, these compounds were primarily screened with cytotoxic, antibacterial, and anti-inflammatory activities. This paper provides insights into the exploration and utilization of bioactive compounds in this genus, both within the scientific field and pharmaceutical industry.

Abstract (sommario):

Purpose: Describe an unusual development of fungal keratitis caused by Acremonium sp in six patients who underwent cataract surgery at an ophthalmology service in Brazil, as well as to report the origin of these infections. Methods: Swabs from the affected corneas were collected to perform culture for bacteria and fungi. These materials were sown in Blood agar (Difco/ USA), Macconkey agar (Difco/USA) and Thioglycolate broth (Difco/USA) for bacterial research and Sabouraud agar (Difco/ USA) for fungi research. A microbiological study was carried out to analyze surgical instruments, the environment and other materials used in the surgeries. Results: Case reports occurred with six patients, all aged over 71 and 85 years, who underwent a surgical procedure for cataract correction by an Ophthalmology service. After surgery, these patients presented loss of unilateral visual capacity, with the formation of a white mass on the cornea. Swabs from the affected corneas were collected to perform culture for bacteria and fungi, in specific culture media. The bacterial cultures showed negative results. Fungal cultures revealed the presence of Acremonium spp. Conclusions: It is likely that Acremonium spores found in the wardrobe were deposited on all the sterile material stored there. At the time of cataract surgeries, this material was unpacked and fungal structures became detached and found in the surgical field of these patients' eyes a gateway. Thus, cleaning and sanitizing measures for surfaces must be implemented and monitored, especially in critical areas such as in hospital areas, in order to avoid damage to patients' health

Abstract (sommario):

Onychomycosis is a common condition constituting fungal infection of nails. It is generally caused by dermatophytes but non-dermatophytic mold and yeast as its causative agent are on the rise. Acremonium, a non-dermatophytic mold, is commonly found in decaying vegetation, soil, and air. Identification of the causative agent is important as non-dermatophytic molds are resistant to commonly used antifungals. This is a case of an Indian woman who presented with onychomycosis of the toenail and the causative agent was documented and reported as Acremonium species.

Laboratory studies were conducted to determine the effects of Acremonium endophytes on four species of billbug (Coleoptera:Curculionidae: Sphenophorus parvulus Gyllenhal, S. venatus (Say), S. inaequalis Say, and S. minimus Hart) found damaging cool-season turfgrasses in New Jersey. Billbug adults feeding on potted tall fescue (Festuca arundinacea Schreb.) plants infected with Acremonium coenophialum Morgan-Jones and Gams showed significantly greater mortality than billbugs feeding on endophyte-free tall fescue. Little difference was observed in amount of feeding. In petri dish preference tests, billbug adults were given a choice and, again, no significant difference was observed in the amount of feeding on endophyte-free versus endophyte-infected tall fescue tillers. In a third experiment, billbug adults were placed in petri dishes with either tall fescue with or without A. coenophialum or perennial ryegrass (Lolium perenne L.) with or without Acremonium lolii Latch, Christensen, and Samuels. Only small differences were seen in number of eggs laid and amount of feeding. Mortality of all four billbug species, however, was greater on both grasses when endophyte-infected.

Abstract (sommario):

Apple fruit spot disease has caused serious economic losses for years in China since the widespread application of fruit bagging in production. Although the three genera Trichothecium, Alternaria, and Acremonium have been reported to be the causal agents, studies on the disease etiology and pathogen biology are still sparse. Here, we report characterization of eight fungal isolates from lesions on 126 symptomatic fruit samples collected in Shaanxi Province, China. Pathogenicity of the isolates was assessed. DNA sequences were obtained at four loci, including D1/D2 domains of the large-subunit nrRNA gene, internal transcribed spacer regions 1 and 2, 5.8S nrDAN gene, a fragment of the actin gene, and a fragment of the β-tubulin. Based on phylogenetic analysis and morphological features, three new species were found: Acremonium mali, Sarocladium liquanensis, and Sarocladium mali. In addition, we made the first report of Sarocladium terricola as a plant pathogen. Temperature and moisture significantly affected in vitro conidial germination of five Acremonium-like species, and their impact on infection of apple fruit was tested using Acremonium sclerotigenum. Conidia of five species germinated from 15 to 35°C in free water; four of the species had optimum temperature around 25°C, whereas conidia of S. terricola had an optimum temperature of 30°C. Conidial germination rate increased as relative humidity (RH) increased. The five isolates had relatively high conidial germination rates at RH > 97%, with a significant decline at 95% RH. Incidence of infection also increased in proportion to RH. In free water, conidial germination was relatively unaffected by temperature.

Abstract (sommario):

This is a rst report about the diversity of micromycetes associated with living thalli of the edible red algae Palmaria palmata (dulse). We collected samples in the Kandalaksha Bay of the White Sea at upper (10 thalli in the littoral) and lower (10 thalli in the sublittoral) lines of this species distribution. The work was carried out by cultural methods, fungi were isolated from the surface of thalli. From one thallus from 0 to 55 colonies belongs to 0-24 morphotypes were isolated. The total diversity was 52 morphotypes, of which 48 were mycelia and 4 were yeast. All identi ed yeasts belong to Basidiomycota; among lamentous fungi, 2 species belongs to Zygomycota, and the rest belongs to Ascomycota, the vast majority of which are represented by anamorphic stages. The most diverse genera were Acremonium (10 morphotypes), Penicillium (9) and Cladosporium (6); the most numerous are Acremonium (158 colonies) and Cladosporium (103 colonies). Acremonium fuci is the most common species on the studied thalli (122 colonies on 15 thalli). The most important factor for the formation of the surface mycobiota of dulse is the habitat: littoral and sublittoral algal populations di er signicantly in the fungal communities number and structure. The thalli of the littoral population are much richer in fungi. The mycobiota of littoral samples in dominated by dark-colored species, as well as Acremonium fuci and Sarocladium strictum. While the mycobiota of sublittoral samples is dominated by lightcolored species, and most of the isolated yeasts were also founded here.
