Saccharomyces cervisiae

Negative results for mutagenicity of d.v-chlordanc and tran.v-chlordanc were reported in various strains of bacteria and in hepatocyte cultures of small mammals. But technical chlordane proved mutagenic to selected strains of Salmonella typhimurium and induced gene conversions in certain strains of the yeast, Saccharomyces cervisiae (IARC 1979 USEPA 1980, 1988 WHO 1984). 

Anti-yeast activity. The essential oil, on agar plate, was inactive on Saccharomyces cervisiae ° . Ethanol (95%) extract of the dried rhizome, in broth culture at a concentration of 10%, was inactive on Candida albicans, Candida glabrata, and Candida tropicalis ° °. Ethanol (90%) extract of the dried rhizome, on agar plate at a concentration of 500 mg/disc, was inactive on Candida albicans ° ... 

The monitoring of cyanide with microbial sensor is possible in two ways. The first principle is based on the inhibition of respiration of Saccharomyces cervisiae by cyanide [102, 103]. This sensor showed a linear response in the range 0-15 pmol 1 by a response time of approximately 10 min and a stability of 9 days. Another method for the determination of cyanide is enabled by the use of cyanide-degrading microorganisms such as Pseudomonas fluorescens [1041. This bacterium specifically oxidizes cyanide by consuming oxygen ... 

An Acanthodendrilla sp. from Japan contained ten steroidal sulfates, acanthosterol sulfates A-J (561-570). Acanthosterol sulfates I (569) and J (570) showed antifungal activity against Saccharomyces cervisiae and its mutants [463]. Clathsterol (571), was isolated from the Red Sea sponge Clathria sp. The structure was established mainly by interpretation of spectral data and a chemical transformation. Clathsterol (571) was active against HIV-1 reverse transcriptase (RT) at a concentration of 10 iM [464]. Toxadocia zumi contains three sterol sulfates (572-574) that are antimicrobial, cytotoxic, ichthyotoxic and larvicidal [465].

The differing abilities of trifluoromethyl and methyl groups to direct enantioselec-tion in the reduction of carbonyl substrates has also been analyzed using various other microorganisms including different strains of G. candidum, Hansenula anom-ala, Saccharomyces cervisiae, Streptomyces, etc.11751. The reduction of the cyclic ketone and enones shown in Fig. 15-29 was investigated. The differences in the electronic and steric properties of the trifluoromethyl and methyl residues resulted in different chemo- and enantioselectivities in the reduction of the phenylbutenones, while the cyclohexanones showed similar enantioselectivities. 

Egg white protein is considered to have one of the best amino acid profiles for human nutrition. Plant proteins generally have lower content of some essential amino acids such as lysine and methionine. Soy protein is one of the best plant proteins, but nevertheless, the most prominent difference in it is the proportion of the essential sulfur-containing amino acid methionine. Egg white protein has approximately three times more methionine than is found in soy protein. The yeast information is for brewer s yeast (Saccharomyces cervisiae).

Similarly, there is evidence that the ATPase activity of Saccharomyces cervisiae is under the control of the mitochondrial genome [190].

Redox reactions In order to mitigate the environmental hazard of 2,4,6-trinitrotoluene (TNT) a procedure was developed for its reduction. Treatment with Saccharomyces cervisiae (32 °C, 3-4 d) converted carbon-14-labeled TNT to a mixture of its four mono-and diamino- metabolites in a one-step procedure.
