Characterization of Tn5 mutants deficient in dissimilatory nitrite reduction in Pseudomonas sp. strain G-179, which contains a copper nitrite reductase.

abstract：:Growth of Streptomyces viridochromogenes on a solid glycerol-NH4NO3 salts medium was accompanied by the formation of aerial mycelia and spores. Adding 0.5% or more casein hydrolysate to the medium stimulated growth while completely repressing the formation of aerial mycelia and spores. This repression was temporary, a...
