Breeding of L-glutamate Oxidase Producing Strains with Mutagenesis and a Rapid Screening Method

When two pieces of white tissue moistened with L-glutamate oxidase(GO) assayed solution were placed on the mature colonies, red spots developed. The speed and the extent of color development could be used to estimate the productivity of the strain tested. By using curent screening method along with HNO_2 mutagenesis, the productivity of GO producing strain P-26 is increased about 25 times within three manthes.
