Interaction among Nystatin and Penicillin G against Saccharomyces cerevisiae

Nystatin-induced changes in Saccharomyces cerevisiae.

Nystatin (5 to 10 mug/ml) was fungicidal to Saccharomyces cerevisiae NCYC 361. There was an initial rapid uptake of nystatin by the yeast cells at 30 C, the uptake being pH dependent, with a maximum at low pH values (3 to 4). Photomicrographs indicated that nystatin-treated cells became granular. The effect of growth temperature on the subsequent sensitivity of the yeast cells to nystatin was i...

G+C content variation along and among Saccharomyces cerevisiae chromosomes.

Past analyses of the genome of the yeast Saccharomyces cerevisiae have revealed substantial regional variation in G+C content. Important questions remain, though, as to the origin, nature, significance, and generality of this variation. We conducted an extensive analysis of the yeast genome to try to answer these questions. Our results indicate that open reading frames (ORFs) with similar G+C c...

Interaction among Saccharomyces cerevisiae pheromone receptors during endocytosis

This study investigates endocytosis of Saccharomyces cerevisiae α-factor receptor and the role that receptor oligomerization plays in this process. α-factor receptor contains signal sequences in the cytoplasmic C-terminal domain that are essential for ligand-mediated endocytosis. In an endocytosis complementation assay, we found that oligomeric complexes of the receptor undergo ligand-mediated ...

Interaction between Saccharomyces cerevisiae and chrysotile.

The interaction between Saccharomyces cerevisiae and chrysotile fibers was studied by scanning electron microscopy. The yeast cells adhere preferentially to the fibrils. In the extreme case, all the adhered fibrils were broken, resulting in a complete coverage of the surface. The chrysotile covered cells showed less buds, but retained metabolic capacities, and were fully active in fermentation ...

Effect of Anti-Microbial Fiber and its Interaction with Penicillin G on Opportunistic Skin Micro-Flora

Objective The standard of hygiene in daily life and hospitals can be increased by the use of new antimicrobial fibers, which diminish the danger of pathogenic bacteria. In this study, the antimicrobial effect of special fibers on some staphylococcus isolates was investigated. Materials and Methods The antimicrobial effect of special type of fibers produced in Isfahan Poly Acryl Plant on thre...
