The possibility of application of micromycetes (strains Penicillium bilaiae Pb14, Aureobasidium pullulans YA05 and Rhodotorula mucilaginosa YR07) to increase yields of soybean (Glycine max cv Almaty) and barley (Hordeum vulgare cv Arna) was estimated. It was shown that the most positive effect on germination energy and seed germination after seed treatment with liquid culture, supernatant and f...

some yeast species play important roles in biological control of some fruits’ post harvest infections. for instant, candida, rhodotorula and pichia species employed in biological control of such post harvest diseases as blue mold (penicillium expansum), and also grey mold (botrytis mali) in apple. species identification of yeasts is some most essential part of the related research activities. d...

The red yeast Rhodotorula mucilaginosa produced an esterase that accumulated in the culture supernatant on induction with triacetin. The enzyme was specific for substrates bearing an O-acetyl group, but was relatively nonspecific for the rest of the molecule, which could consist of a phenol, a monosaccharide, a polysaccharide, or an aliphatic alcohol. The esterase was more active against acetyl...

Thirty-eight specimens of free-ranging Podocnemis expansa (Amazon turtle) and 22 of P. unifilis (Tracajá) were screened for yeast isolation from surface (plastron, skin, and nails), eye, and mouth cavity. A hundred and eighteen yeast isolates belonging to 39 species were obtained. Debaryomyces hansenii, Candida galli, C. sake, and Rhodotorula mucilaginosa were the most frequent species isolated...

178 yeasts isolated from various foods were identified using ID32 C strip; Saccharomyces cerevisiae (47), Rhodotorula mucilaginosa (19), Candida kefyr (33), Candida krusei (37), Candida lusitaniae (28), Cndida lipolytica (14). The yeasts were harvested, saponified, derivatized, and extracted, and fatty acid analysis was performed by Gas Chromatography Mass Spectrometry. The yeast lipids contain...

A pigmented yeast R1 with strong tolerance to Hg2+ was isolated. Phylogenetic identification based on the analysis of 26S rDNA and ITS revealed R1 is a Rhodotorula mucilaginosa species. R1 was able to grow in the presence of 80 mg/L Hg2+, but the lag phase was much prolonged compared to its growth in the absence of Hg2+. The maximum Hg2+ binding capacity of R1 was 69.9 mg/g, and dead cells coul...
