Selection of wine yeasts for growth and fermentation in the presence of ethanol and sucrose
(American Society for Microbiology, 1983)
To optimize the conversion of carbohydrates to ethanol, strains of several Saccharomyces species were examined for the ability to grow and ferment in a range of sucrose and ethanol concentrations. A total of 632 wine yeasts, ...

Gibberella fujikuroi mutants obtained with UV radiation and N-methyl-N'-nitro-N-nitrosoguanidine
(American Society for Microbiology, 1985)
N-methyi-N'-nitro-N-nitrosoguanidine (nitrosoguanidine) and to a lesser extent UV radiation are very mutagenic for Gibberella microconidia. The recommended nitrosoguanidine doses lead to much higher frequencies of mutants ...

Isolation of ntrA-like mutants of Azobacter vinelandii
(American Society for Microbiology, 1986)
A number of of chlorate-resistant mutants of Azotobacter vinelandii affected in a general control of nitrogen metabolism were isolated. These mutants could not utilize dinitrogen, nitrate, or nitrite as a nitrogen source. ...

Adaptation of yeast cell membranes to ethanol
(American Society for Microbiology, 1987)
A highly ethanol-tolerant Saccharomyces wine strain is able, after growth in the presence of ethanol, to efficiently improve the ethanol tolerance of its membrane. A less-tolerant Saccharomyces laboratory strain, however, ...

Induction of petite yeast mutants by membrane-active agents
(American Society for Microbiology, 1988)
Ethanol proved to be a strong mutagenic agent of Saccharomyces mitochondrial DNA. Other active membrane solvents, such as tert-butanol, isopropanol, and sodium dodecyl sulfate, also turned out to be powerful petite mutation ...

Variation in G+C-content and codon choice: Differences among synonymous codon groups in vertebrate genes
(Oxford University Press, 1989)
The relationship between G+C-content and codon usage in genes of human, mus, rat, bovine and chicken nuclear genomes was investigated. Correlation and lineal regression analyses were carried out on plots that related the ...

Intergeneric hybrids of Saccharomyces cerevisiae and Zygosaccharomyces fermentati obtained by protoplast fusion
(American Society for Microbiology, 1986)
To obtain strains that are able to efficiently produce ethanol from different carbohydrates, mainly cellulose hydrolysates, several species of the genus Candida and a Zygosaccharomyces fermentati ...
