Biotransformation of ten α-haloacetophenones in the growing culture of the strain Rhodotorula rubra KCh 82 has been carried out. Nine of the substrates underwent an effective enantioselective reduction to the respective (R)-alcohols according to Prelog's rule, with the exception of 2-chloro-1,2-diphenylethan-1-one that was not transformed by this strain. The expected reduction proceeded without...
This study aimed at isolating and characterizing of microorganisms able to use linamarin as sole carbon source. Thirty one microbial strains were isolated from manipueira, a liquid effluent of cassava processing factories. Among these strains, Bacillus licheniformis (isolate 2_2) and Rhodotorulla glutinis (isolate L1) were able to degrade 71% and 95% of added linamarin, respectively, within 7 d...
Torulene and torularhodin represent the group of carotenoids and are synthesized by yeasts and fungi. The most important producers of these two compounds include yeasts of Rhodotorula and Sporobolomyces genera. The first reports confirming the presence of torulene and torularhodin in the cells of microorganisms date to the 1930s and 1940s; however, only in the past few years, the number of work...
Milk fan is an acid-curd cheese with strong national characteristics (a traditional dairy product of the Bai nationality shape like a piece paper) and long history in Yunnan province, China. In our previous study, we characterized microbial community diversity milk fan,but succession microorganisms associated flavor formation still unknown. Therefore, examined predominant their correlations fer...
هدف از این پژوهش تعیین ارزش غذایی برخی از گونههای غالب جلبک دریایی ایران با استفاده از روشهای آزمایشگاهی در قالب طرح کاملا تصادفی به صورت 3 آزمایش جداگانه انجام شد. گونههای جلبک عبارت بودند از: انترومورفا1، انترومورفا2، اولوا لینزیا، ساراگاسوم، گراسیلاریوپسیز پرسیکا، هئیپنا فلجلفرمیس. آزمایش اول جهت تعیین کینتیک تولید گاز نمونه ها، آزمایش دوم جهت تعیین قابلیت هضم و تخمیر شکمبه ای نمونه ها انجام...
The effect of Rhodotorula mucilaginosa in combination with phytic acid (PA) on blue mold decay and patulin contamination of apples was investigated. Results from this study show that different concentrations of PA were effective in reducing the disease incidence of apples and that PA at concentration of 4 μmol/mL, decreased the incidence of blue mold decay in apples from 86.1 to 62.5%, and show...
A procedure is given for the coupling of fluorescein isothiocyanate to concanavalin A, a protein which specifically combines with a variety of polysaccharides, and for the subsequent isolation of the reactive conjugate. This fluorescent conjugate stains Saccharomyces cerevisiae but not Schizosaccharomyces pombe or Rhodotorula glutinis. The cell walls of the latter two organisms do not contain b...
UNLABELLED We propose a model, based on the Gompertz equation, to describe the growth of yeasts colonies on agar medium. This model presents several advantages: (i) one equation describes the colony growth, which previously needed two separate ones (linear increase of radius and of the squared radius); (ii) a similar equation can be applied to total and viable cells, colony area or colony radiu...
