The effects of KCl, NaCl, and LiCl on the growth of Debaryomyces hansenii, usually considered a halotolerant yeast, and Saccharomyces cerevisiae were compared. KCl and NaCl had similar effects on D. hansenii, indicating that NaCl created only osmotic stress, while LiCl had a specific inhibitory effect, although relatively weaker than in S. cerevisiae. In media with low K+, Na+ was able to subst...

Saccharomyces kluyveri is a heterothallic yeast with two allelic mating types denoted as a-k and alpha-k by analogy with Saccharomyces cerevisiae and from the work described here. S. kluyveri produces mating pheromones analogous to those of S. cerevisiae, but which appear to have different specificity. S. kluyveri thus differs from S. cerevisiae, Hansenula wingei, and Schizosaccharomyces pombe ...

We report a large-scale comparison of sequence data from the filamentous fungus Neurospora crassa with the complete genome sequence of Saccharomyces cerevisiae. N. crassa is considerably more morphologically and developmentally complex than S. cerevisiae. We found that N. crassa has a much higher proportion of "orphan" genes than S. cerevisiae, suggesting that its morphological complexity refle...

Morphogenesis and adhesion to host tissues and medical devices contribute to the virulence of Candida albicans, the most common fungal pathogen isolated from humans. However, identification of molecular mechanisms of C. albicans adhesion and morphogenesis has been impaired by the lack of effective molecular and genetic tools available for this organism. Saccharomyces cerevisiae provides an attr...

Genes involved in ribosome biogenesis and assembly (RBA) are responsible for ribosome formation. In Saccharomyces cerevisiae, their transcription is regulated by two dissimilar DNA motifs. We were interested in analyzing conservation and divergence of RBA transcription regulation machinery throughout fungal evolution. We have identified orthologs of S. cerevisiae RBA genes in 39 species across ...

Cider flavor has a very important impact on the quality. Solid-phase microextraction-gas chromatography–mass spectrometry (SPME-GC-MS) combined with gas chromatography–ion mobility (GC-IMS) tested different kinds of non-Saccharomyces yeasts and Saccharomyces cerevisiae (S. cerevisiae) co-inoculated for fermentation cider to determine differences in aroma material, determination odor activity va...

We report the sequences of two genomic regions from the pathogenic yeast Candida glabrata and their comparison to Saccharomyces cerevisiae. A 3 kb region from C. glabrata was sequenced that contains homologues of the S. cerevisiae genes TFB3, MRPL28 and STP1. The equivalent region in S. cerevisiae includes a fourth gene, MFA1, coding for mating factor a. The absence of MFA1 is consistent with C...

Candida glabrata is an opportunistic fungal pathogen that can cause severe invasive infections and can evade phagocytic cell clearance. We are interested in understanding the virulence of this fungal pathogen, in particular its oxidative stress response. Here we investigated C. glabrata, Saccharomyces cerevisiae and Candida albicans responses to two different oxidants: menadione and cumene hydr...

Saccharomyces cerevisiae, a well-established model for species as diverse as humans and pathogenic fungi, is more recently a model for population and quantitative genetics. S. cerevisiae is found in multiple environments-one of which is the human body-as an opportunistic pathogen. To aid in the understanding of the S. cerevisiae population and quantitative genetics, as well as its emergence as ...


 Banana peels belong to lignocellulosic substrates, which can be used as raw material for bioethanol. Yeast plays an essential role in bioethanol fermentation. The study aims compare ethanol yield using two different yeasts: Saccharomyces cerevisiae and Rhizopus oryzae, with yeast concentrations of 2, 3, 5 g/L. fermentation is run at room temperature 120 hours. Results show that R. oryzae...
