Studies on the organization of genes controlling lysine biosynthesis in neurospors crassa IV. Segregation patterns, maturity and viability of ascospora and conidiation of some lys05 mutants .
Studies on 39 U.V. induced lys-5 mutants have shpwn that a mutation at this locus not only results in a requirement for lysine but also retards the maturation of spores. The mutant spores lack pigment...

Effect of different oxygen pressures and of age on changes in catalase and peroxidase activities of rhizopus oryzae under high pressures of oxygen.
Changes in catalase activity of rhizopus oryzae on ethanol medium under high pressures of oxygen varied with varying pressure. The optimum pressure for induced increase of catalase was found to be 4 a...
