Successive reculturing of Torulopsis glabrata on media containing increasing concentration of the polyene macrolide antibiotics nystalin or lucensomycin resulted in the segregation of cultures resistant to these antibiotics. Isolates resistant to lucensomycin showed good resistance to nystatin, and vice versa. Analysis of the sterols and fatty acids of(More)
The role of 4,4-dimethylzymosterol (3), 4,4-dimethylfecosterol (4) and 31-norlanosterol (5) in the biosynthesis of ergosterol in Saccharomyces cerevisiae has been investigated. The synthesis of 4 and 5 coupled with the availability of 3 facilitated a search for these sterols in commercial yeast sterol concentrates, fresh laboratory grown yeast and fresh(More)
