Trans-cinnamic acid and p-coumaric are valuable intermediates in the synthesis of flavonoids widely employed food, flavor pharmaceutical industries. These products can be produced by deamination L-phenylalanine L-tyrosine catalyzed phenylalanine ammonia lyase or tyrosine lyase. Phenylalanine ammonia-lyase (PAL, EC 4.3.1.5) from Rhodotorula glutinis do not exhibit strong substrate specificity co...

BACKGROUND The feasibility of heterotrophic-phototrophic symbioses was tested via pairing of yeast strains Cryptococcus curvatus, Rhodotorula glutinis, or Saccharomyces cerevisiae with a sucrose-secreting cyanobacterium Synechococcus elongatus. RESULTS The phototroph S. elongatus showed no growth in standard BG-11 medium with yeast extract, but grew well in BG-11 medium alone or supplemented ...

Fermented sausage, produced by traditional methods, matures fermentation of microbial flora originating from the raw materials and place production. The source contamination meat industry with yeasts, which are widespread in environment, surfaces tools equipment used processing. Although presence yeasts products contributes to formation flavor aroma, some yeast species can cause undesirable fla...

The aim of this study is to compare the production of biomass enriched with carotenoids and ergosterol by yeast strain Rhodotorula glutinis CCY 20-2-26 grown under optimal growth conditions and in the presence of exogenous stress factors. R. glutinis cells were exposed to UV irradiation, oxidative stress (2–10 mmol/L H2O2) and osmotic stress (2–10 % NaCl). During the experiment, growth characte...

It had been known before [2, 8, 9, 10] that the herbicides of the carbamates group strongly affect physiology of microorganisms. The aim of the present work was to gain an insight into the action of the herbicide CIPC (isopropyl-N/3-chlorphenyl carbamate) on the cells of soil yeast Rhodotorula glutinis, as a model of soil microflora. Attention has been paid to the following questions: the effec...
