Also ascomycetes yeast strains showed decolorizing behaviors due to extracellular reactions on polar dyes. The process occur when an alternative carbon and energy source is available. The involvement of an externally directed plasma membrane redox system was suggested in S. cerevisiae, the plasma membrane ferric reductase system participates in the extracellular reduction of azo dyes [25]. 

The majority of ascomycetous yeasts form cell-wall mannans or ga-lactomannans having main chains of (1— 6)-linked a-D-mannopyrano-syl residues, often substituted at 0-2 by a-linked glycosyl groups. The linkage types in the rest of the side chains vary widely, and can consist of 2-O-substituted a- or /3-D-mannopyranosyl residues, or 3-O-substi-...

Based on 18S ribosomal DNA sequencing, we have traced back the uninucleate ascomycetous yeasts Kluyveromyces, Saccharomyces) to a polykaryotic (Eremothecium) ancestor [152].

The ability of yeast cells to liberate sphaeroplasts following treatment with (1-> 3)-/3-D-glucanases has been proposed as a taxonomic criterion for differentiating basidiomycetous from ascomycetous yeasts and for classifying the yeasts of the fungi imperfecti. ...

Fungi are used extensively as model developmental systems in biochemistry and genetics. An early classical study of steroid-mediated morphogenesis involved the Oomycete Ac/i/ya ambisexualis (Raper 1939, 1940). The ascomycetous yeast Saccharomyces cerevisiae is the most extensively studied eukaryote in many areas of signal transduction (Kurjan 1993 Ferguson et al. 1994 Grishin et al. 1994 Schultz et al. 1995), especially as it relates to cell division and sexual reproduction.
