Abstract:

The giant-celled algae Chara and Nitella have been used extensively in studies of the transport of ions and other solutes. Before this report, uptake measurements were made without a detailed consideration of the effects of microbial epiphytes living on the external surface of the algal cell wall. Examination of the cell walls of Chara and Nitella with the scanning electron microscope revealed the presence of an often dense microflora consisting of diatoms, many types of bacteria, and even fungi. The contribution of this microflora to uptake measurements made with radiotracers was estimated by

The horizontal and vertical distributions of cyanobacteria and algae on soil polygons on Signy Island were investigated.

Phormidium autumnale was the most widespread taxon, and other Oscillatoriaceae were also important, although large differences in community composition between polygons were observed.

It also suggests an evolutionary link to the Recent genus Galaxaura (order Nemalionales; family Chaetangiaceae), which is the only extant alga bearing a similarity to the Gymnocodiaceae.

Most foraminifers and algae described from the Maritimes Basin are considered cosmopolitan, and the occurrence in western Europe and northern Africa of taxa previously considered endemic to the North America Realm suggests a close paleobiogeographic relationship.

Abstract:

Ecological catastrophes can take many forms, and can come in all shapes and sizes! Nitrogenous fertilisers can be washed off farm-land into lakes and ponds, resulting in overgrowth by algae. Such an overgrowth can lead to secondary effects to the ecosystem; the algae can consume dissolved oxygen in the water leading to the loss of aerobic microbial, plant and insect life (eutrophication). Similarly, atmospheric pollution with sulphur dioxide and nitrogen oxides can produce acid rain causing damage to plants and trees and loss of aquatic life.

Abstract:

Three marine algal microfloral realms are recognized in the Carboniferous: (i) a Tethyan flora with numerous Dasycladales and high endemism, (ii) a North American flora with some Dasycladales and fairly low endemism, and (iii) an Arctic flora composed of Dasycladales in low numbers and with cosmopolitan assemblages. These three phytochores are interconnected by a high number of "cosmopolitan" genera and species. However "transatlantic" exchanges are limited. The floras of the American exotic terranes (Peratrovich type) have some tethyan affinities but are basically cosmopolitan.

Abstract:

Aquaculture is based on the use of compound feed, which accounts for about 70–80% of costs. Due to their biological needs, metabolic characteristics and habitat, fish are more demanding on the quality of feed, the main suppliers of which in the Republic of Belarus are foreign firms. This leads to an increase in the cost of production and significantly hinders the development of aquaculture, therefore, when developing formulations of domestic mixed feeds for juvenile fish of valuable species, it is necessary to rely on the use of inexpensive, affordable and effective components.

Abstract:

ABSTRACTThe upper half of the Archerbeck Borehole contains a continuous Mississippian succession from the late Asbian (late Viséan) to the Pendleian (early Serpukhovian), with numerous limestone horizons. The borehole sequence lies within the Solway Basin (western end of the Northumberland Trough) and bridges the successions between the Midland Valley of Scotland and the Pennines (northern England). The rich foraminiferal and algal assemblages are compared to those described by previous authors, and genera as well as species are updated as far as is possible. In addition, some other overlooked

AbstractMicroflora of cyanobacteria and algae of small forest dystrophic Lake Sęczek located in the Masurian Lake District, NE Poland, was investigated in 2012 and 2013. A total of 16 genera with 7 species of cyanobacteria and 56 genera with 74 species, 6 varietas and forms of algae were determined. Most of them represented commonly occurring microorganisms of slightly acidic waters, but some of them are considered rare, i.e. the oscillatorian cyanobacterium Katagnymene accurata Geitler (for the first time found in Poland), and green algae Coenochloris sphagnicola Hindák, Mucidosphaerium sphag

Abstract:

The diversity of cyanobacteria and algae from various microhabitats in Spitsbergen is comparatively well known. However, the relationships between environmental factors and the structure of microflora communities remain largely unclear. This study was conducted in Hornsund Bay, which exhibits large variability in the physicochemical characteristics of habitats, particularly with regard to the availability of nitrogen and phosphorus. This variability, to a large degree, is caused by seabird colonies, which fertilize nutrient-poor terrestrial ecosystems near their nesting areas. The large variat

AbstractThe paper reports state of the art research in the field of novel bio-based products for agriculture. Biopesticides, biostimulants and biofertilizers were shown as a potential alternative or additional products to the currently used agrochemicals. The present situation on the market of agrochemicals was discussed. Difficulties related to products registration were taken into account. Research on supercritical algal extracts as a biostimulant of plant growth and health supporting feed additive for laying hens was presented, as well as the perspectives of the use of biomass as the carrie

Background: Microbial biomass is a valuable resource to the development of sustainable energy. However, the challenge of having an effective media for energy production have adversely affected biotechnological development. This study was aimed at comparing algal biomass produced by Chlorella sp. using hot and cold water extracts of poultry droppings. Methodology: Fifteen grams (15 g) of poultry droppings was infused into 500 mL (cold and hot water) and allowed to stand for 48 h prior. Algal growth was monitored by cell dry weight and optical density readings taken at 620 nm using a spect

Abstract:

ABSTRACT Pseudoalteromonas piscicida is a Gram-negative gammaproteobacterium found in the marine environment. Three strains of pigmented P. piscicida were isolated from seawater and partially characterized by inhibition studies, electron microscopy, and analysis for proteolytic enzymes. Growth inhibition and death occurred around colonies of P. piscicida on lawns of the naturally occurring marine pathogens Vibrio vulnificus, Vibrio parahaemolyticus, Vibrio cholerae, Photobacterium damselae, and Shewanella algae. Inhibition also occurred on lawns of Staphylococcus aureus but not on Escherichia
