A test for the nitrate-reductase activity in yeasts has been developed, in which the reaction may be read after only 10 min of incubation. The rapidity of the test is due to the optimization of pH, substrate concentration, and temperature for the reaction.
Yeasts from caves have rarely been examined. We examined yeasts collected from bat guano samples from 20 bat-inhabited limestone and volcanic caves located in 11 prefectures in Japan. Of approximately 700 yeast-like colonies, nine Trichosporon species were recovered from 15 caves. Two of these were known species, and the remaining seven are potentially novel species, based on molecular phylogen...
An extensive computer-assisted identification system for bacteria and yeasts (117 genera and 1,430 species) was developed, and applications proved very useful in teaching situations.
To establish the historical prevalence of the novel yeast species Candida dubliniensis, a survey of 2,589 yeasts originally identified as Candida albicans and maintained in a stock collection dating back to the early 1970s was undertaken. A total of 590 yeasts, including 93 (18.5%) beta-glucosidase-negative isolates among 502 isolates that showed abnormal colony colors on a differential chromog...
Brewing yeasts of the genus Saccharomyces are either available from yeast distributor centers or from breweries employing their own "in-house strains". During the last years, the classification and characterization of yeasts of the genus Saccharomyces was achieved by using biochemical and DNA-based methods. The current lack of fast, cost-effective and simple methods to classify brewing yeasts t...
