The use of carbohydrates as cryoprotectants is increasing. In this study the effects of incorporating polysaccharides extracted from plants and microalgae originating in northern Russia, into cryoprotectant solutions used to preserve human white blood cells were investigated. Cells in the presence of the polysaccharides were cooled to either -40°C or -80°C,(More)
In studying the beta-xylosidase production by yeast Cryptococcus podzolicus (Basidiomycetes), it was shown to be an inducible secretory enzyme. Xylooligosaccharides generated from xylan and methyl beta-xyloside were found to induce the beta-xylosidase synthesis. The enzyme activity in the medium containing xylan or methyl beta-xyloside was 1.0 and 1.5 U/ml,(More)
The chitinolytic activity of nine species of filamentous fungi, classified with seven genera (specifically, Aspergillus, Penicillium, Trichoderma, Paecilomyces, Sporotrichum, Beaueria, and Mucor), was studied. When cultured in liquid medium containing 1% crystalline chitin, all fungi produced extracellular chitosans with activity varying from 0.2 U/mg(More)
Oil biosorbents (patents 2299181, 2318736) were obtained using immobilization of oil-oxidizing microorganisms into the hydrophobic sorbent Sorbonaft, which is manufactured using special technology at the Press-Torf Company. Two associations of aboriginal hydrocarbon-oxidizing microorganisms were used for this purpose: a fungal association and a bacterial(More)
