Abstract:

Three strains, LMG 27748T, LMG 27749 and LMG 27882 with identical MALDI-TOF mass spectra were isolated from samples taken from the brewery environment. Analysis of the 16S rRNA gene sequence of strain LMG 27748T revealed that the taxon it represents was closely related to type strains of the species Gluconobacter albidus (100 % sequence similarity), Gluconobacter kondonii (99.9 %), Gluconobacter sphaericus (99.9 %) and Gluconobacter kanchanaburiensis (99.5 %). DNA–DNA hybridization experiments on the type strains of these species revealed moderate DNA relatedness values (39–65 %). The three strains used d-fructose, d-sorbitol, meso-erythritol, glycerol, l-sorbose, ethanol (weakly), sucrose and raffinose as a sole carbon source for growth (weak growth on the latter two carbon sources was obtained for strains LMG 27748T and LMG 27882). The strains were unable to grow on glucose-yeast extract medium at 37 °C. They produced acid from meso-erythritol and sucrose, but not from raffinose. d-Gluconic acid, 2-keto-d-gluconic acid and 5-keto-d-gluconic acid were produced from d-glucose, but not 2,5-diketo-d-gluconic acid. These genotypic and phenotypic characteristics distinguish strains LMG 27748T, LMG 27749 and LMG 27882 from species of the genus Gluconobacter with validly published names and, therefore, we propose classifying them formally as representatives of a novel species, Gluconobacter cerevisiae sp. nov., with LMG 27748T ( = DSM 27644T) as the type strain.

Abstract:

<em>Gluconobacter</em> species are capable of incomplete oxidations which are exploited in food biotechnology. Levans isolated from exopolysaccharide (EPS)-overproducing <em>Gluconobacter</em> species are promising functional compounds for food applications. Fructan production strongly depends on the corresponding fructosyltransferases (Ftfs), which catalyze the formation of these polymers from sucrose. Therefore, we characterized novel Ftfs from three EPS-overproducing food-grade strains, i.e. <em>Gluconobacter</em> sp. TMW 2.767 and <em>Gluconobacter</em> sp. TMW 2.1191 isolated from water kefir, and <em>Gluconobacter cerinus</em> DSM 9533T isolated from cherries. Several PCR techniques, including degenerate gradient temperature PCR, modified and standard inverse PCR, modified site-finding PCR and modified single primer PCR, were used to finally detect complete open reading frames coding for Ftfs. The prospective ftf-gene sequences were heterologously expressed in <em>Escherichia coli</em> Top 10. <em>E. coli</em> transformants harboring one of the three different ftf-genes produced polysaccharides from sucrose in contrast to the <em>E. coli</em> wildtype. Each of the heterologously expressed proteins encoded a levansucrase, catalyzing the formation of b-(2→6)-linked fructose polymers, which corresponded to our previous analyses about the chemical nature of the isolated polymers formed by these <em>Gluconobacter</em> strains. Structurally, these enzymes belong to the glycoside hydrolase 68 family (GH 68), sharing the typical modular topology of levansucrases from gram-negative bacteria. In conclusion, we could identify novel active levansucrases, which can be used for <em>ex situ</em> (enzymatic catalyses) or <em>in situ</em> (fermentation) production of functional fructan polymers by <em>Gluconobacter</em> strains in food and other applications.

Abstract:

Two bacterial strains, isolates AC10T and AC20, which were reported in a previous study on the diversity of acetic acid bacteria in Thailand, were subjected to a taxonomic study. The phylogenetic analysis based on the 16S rRNA gene sequences showed that the two isolates were located closely to the type strains of Gluconobacter oxydans and Gluconobacter roseus . However, the two isolates formed a separate cluster from the type strains of the two species. The genomic DNA of isolate AC10T was sequenced. The assembled genomes of the isolate were analysed for average nucleotide identity (ANI) and digital DNA–DNA hybridization (dDDH). The results showed that the highest ANI and dDDH values between isolate AC10T and G. oxydans DSM 3503T were 91.15 and 68.2 %, which are lower than the suggested values for species delineation. The genome-based tree was reconstructed and the phylogenetic lineage based on genome sequences showed that the lineage of isolate AC10T was distinct from G. oxydans DSM 3503T and its related species. The two isolates were distinguished from G. oxydans and their relatives by their phenotypic characteristics and MALDI-TOF profiles. Therefore, the two isolates, AC10T (=BCC 15749T=TBRC 11329T=NBRC 103576T) and AC20 (=BCC 15759=TBRC 11330=NBRC 103579), can be assigned to an independent species within the genus Gluconobacter , and the name Gluconobacter aidae sp. nov. is proposed for the two isolates.

Abstract:

Sixty-six acetic acid bacteria (AAB) were isolated from fourty-five flowers and fruits collected in Hochiminh City, Vietnam. Of the sixty-six, thirty-one isolates were selected as dihydroxyacetone (DHA)-producing AAB based on the reaction with Fehling’s solution and grouped into three groups by routine identification with phenotypic features. Group I composed of fourteen isolates and was assigned to the genus Acetobacter, Group II composed of thirteen isolates and was assigned to the genus Gluconobacter and Group III was the remaining four isolates and was assigned to the genus Gluconacetobacter. Ten isolates among the thirteen isolates of Group II gave a larger amount of DHA (22.2–26.0 mg/mL) than Gluconobacter oxydans NBRC 14819T (19.8 mg/mL), promising for the potential use in producing DHA. In phylogenetic analysis based on 16S rRNA gene sequences, six isolates of the ten potential DHA producers were suggested to be candidates for new taxa in the genus Gluconobacter.

Abstract:

N-2-hydroxyethyl-glucamine (NHEG) was converted into 6-deoxy-6-hydroxylethyl-amino-L-sorbose (DHES) by the regioselective oxidation of Gluconobacter oxydans, and then the generated intermediate of this process was produced to N-hydroxyethyl-deoxynojirimycin (Miglitol) by reductive ring closure reaction. Regioselective oxidation reaction was catalyzed by the high activity sorbitol dehydrogenase of Gluconobacter oxydans biomass which was obtained in preliminary studies. Reductive ring closure reaction was carried out under the conditions of 10%Pd/C as catalyst, at 45~55°C and 0.6MPa of hydrogen. Reaction mixture by the separation and purification of strong acidic exchange resin column has been the Miglitol. In addition, the structure and properties of synthetic product was characterized by thin layer chromatography (TLC), melting point, mass spectrometry (MALDI-MS), Fourier transform infrared spectroscopy (FTIR) analysis. The results showed that the miglitol yield is 77.3%.The regional specificity of the high activity sorbitol dehydrogenase of Gluconobacter oxydans has been verified. Moreover, combinating the technology of the Pd/C- catalyzed reductive ring closure reaction, an effective synthesis process of miglitol is achieved.

Abstract:

Abstract There is an increasing public awareness about the danger of dietary sugars with respect to their caloric contribution to the diet and the rise of overweight throughout the world. Therefore, low-calorie sugar substitutes are of high interest to replace sugar in foods and beverages. A promising alternative to natural sugars and artificial sweeteners is the fructose derivative 5-keto-D-fructose (5-KF), which is produced by several Gluconobacter species. A prerequisite before 5-KF can be used as a sweetener is to test whether the compound is degradable by microorganisms and whether it is metabolized by the human microbiota. We identified different environmental bacteria (Tatumella morbirosei, Gluconobacter japonicus LMG 26773, Gluconobacter japonicus LMG 1281, and Clostridium pasteurianum) that were able to grow with 5-KF as a substrate. Furthermore, Gluconobacter oxydans 621H could use 5-KF as a carbon and energy source in the stationary growth phase. The enzymes involved in the utilization of 5-KF were heterologously overproduced in Escherichia coli, purified and characterized. The enzymes were referred to as 5-KF reductases and belong to three unrelated enzymatic classes with highly different amino acid sequences, activities, and structural properties. Furthermore, we could show that 15 members of the most common and abundant intestinal bacteria cannot degrade 5-KF, indicating that this sugar derivative is not a suitable growth substrate for prokaryotes in the human intestine. Key points • Some environmental bacteria are able to use 5-KF as an energy and carbon source. • Four 5-KF reductases were identified, belonging to three different protein families. • Many gut bacteria cannot degrade 5-KF.

Abstract:

Three strains, RBY-1T, PHD-1 and PHD-2, were isolated from fruits in Thailand. The strains were Gram-negative, aerobic rods with polar flagella, produced acetic acid from ethanol and did not oxidize acetate or lactate. In phylogenetic trees based on 16S rRNA gene sequences and 16S–23S rRNA gene internal transcribed spacer (ITS) sequences, the strains formed a cluster separate from the type strains of recognized species of the genus Gluconobacter. The calculated 16S rRNA gene sequence and 16S–23S rRNA gene ITS sequence similarities were respectively 97.7–99.7 % and 77.3–98.1 %. DNA G+C contents ranged from 57.2 to 57.6 mol%. The strains showed high DNA–DNA relatedness of 100 % to one another, but low DNA–DNA relatedness of 11–34 % to the tested type strains of recognized Gluconobacter species. Q-10 was the major quinone. On the basis of the genotypic and phenotypic data obtained, the three strains clearly represent a novel species, for which the name Gluconobacter nephelii sp. nov. is proposed. The type strain is RBY-1T ( = BCC 36733T = NBRC 106061T = PCU 318T), whose DNA G+C content is 57.2 mol%.

Abstract:

ABSTRACT During a previous study on the molecular interaction between commensal bacteria and host gut immunity, two novel bacterial strains, A911T and G707T, were isolated from the gut of Drosophila melanogaster. In this study, these strains were characterized in a polyphasic taxonomic study using phenotypic, genetic, and chemotaxonomic analyses. We show that the strains represent novel species in the family Acetobacteraceae. Strain G707T, a highly pathogenic organism, represents a new species in the genus Gluconobacter, “Gluconobacter morbifer” sp. nov. (type strain G707 = KCTC 22116T = JCM 15512T). Strain A911T, dominantly present in the normal Drosphila gut community, represents a novel genus and species, designated “Commensalibacter intestini” gen. nov., sp. nov. (type strain A911 = KCTC 22117T = JCM 15511T).

Full text

Abstract:

Coffee beans derived from feces of the civet cat are used to brew coffee known as kopi luwak (the Indonesian words for coffee and palm civet, respectively), which is one of the most expensive coffees in the world owing to its limited supply and strong market demand. Recent metabolomics studies have revealed that kopi luwak metabolites differ from metabolites found in other coffee beans. To produce kopi luwak, coffee beans are first eaten by civet cats. It has been proposed that fermentation inside the civet cat digestive tract may contribute to the distinctively smooth flavor of kopi luwak, but the biological basis has not been determined. Therefore, we characterized the microbiome of civet cat feces using 16S rRNA gene sequences to determine the bacterial taxa that may influence fermentation processes related to kopi luwak. Moreover, we compared this fecal microbiome with that of 14 other animals, revealing that Gluconobacter is a genus that is, uniquely found in feces of the civet cat. We also found that Gluconobacter species have a large number of cell motility genes, which may encode flagellar proteins allowing colonization of the civet gut. In addition, genes encoding enzymes involved in the metabolism of hydrogen sulfide and sulfur-containing amino acids were over-represented in Gluconobacter. These genes may contribute to the fermentation of coffee beans in the digestive tract of civet cats.

Abstract:

ABSTRACT Acetic acid bacteria, especially Gluconobacter species, have been known to catalyze the extensive oxidation of sugar alcohols (polyols) such as d-mannitol, glycerol, d-sorbitol, and so on. Gluconobacter species also oxidize sugars and sugar acids and uniquely accumulate two different keto-d-gluconates, 2-keto-d-gluconate and 5-keto-d-gluconate, in the culture medium by the oxidation of d-gluconate. However, there are still many controversies regarding their enzyme systems, especially on d-sorbitol and also d-gluconate oxidations. Recently, pyrroloquinoline quinone-dependent quinoprotein d-arabitol dehydrogenase and d-sorbitol dehydrogenase have been purified from G. suboxydans, both of which have similar and broad substrate specificity towards several different polyols. In this study, both quinoproteins were shown to be identical based on their immuno-cross-reactivity and also on gene disruption and were suggested to be the same as the previously isolated glycerol dehydrogenase (EC 1.1.99.22). Thus, glycerol dehydrogenase is the major polyol dehydrogenase involved in the oxidation of almost all sugar alcohols in Gluconobacter sp. In addition, the so-called quinoprotein glycerol dehydrogenase was also uniquely shown to oxidize d-gluconate, which was completely different from flavoprotein d-gluconate dehydrogenase (EC 1.1.99.3), which is involved in the production of 2-keto-d-gluconate. The gene disruption experiment and the reconstitution system of the purified enzyme in this study clearly showed that the production of 5-keto-d-gluconate in G. suboxydans is solely dependent on the quinoprotein glycerol dehydrogenase.

Abstract:

ABSTRACT We isolated thermotolerant Gluconobacter strains that are able to produce 5-keto-d-gluconic acid (5KGA) at 37°C, a temperature at which regular mesophilic 5KGA-producing strains showed much less growth and 5KGA production. The thermotolerant strains produced 2KGA as the major product at both 30 and 37°C. The amount of ketogluconates produced at 37°C was slightly less than the amount produced at 30°C. To improve the yield of 5KGA in these strains, we disrupted flavin adenine dinucleotide-gluconate dehydrogenase (FAD-GADH), which is responsible for 2KGA production. Genes for FAD-GADH were cloned by using inverse PCR and an in vitro cloning strategy. The sequences obtained for three thermotolerant strains were identical and showed high levels of identity to the FAD-GADH sequence reported for the genome of Gluconobacter oxydans 621 H. A kanamycin resistance gene cassette was used to disrupt the FAD-GADH genes in the thermotolerant strains. The mutant strains produced 5KGA exclusively, and the final yields were over 90% at 30°C and 50% at 37°C. We found that the activity of pyrroloquinoline quinone (PQQ)-dependent glycerol dehydrogenase, which is responsible for 5KGA production, increased in response to addition of PQQ and CaCl2 in vitro when cells were grown at 37°C. Addition of 5 mM CaCl2 to the culture medium of the mutant strains increased 5KGA production to the point where over 90% of the initial substrate was converted. The thermotolerant Gluconobacter strains that we isolated in this study provide a promising new option for industrial 5KGA production.
