Abstract
L-Histidine producing microorganisms which have been constructed by introducing a recombinant plasmid DNA inserted on a chromosomal DNA fragment into a recipient strain of the genus Bacillus. These microorganisms are employed to produce L-histidine in higher than normal yields. The recombinant plasmid DNA inserted is obtained from a donor mutant strain of Bacillus subtilis which is resistant to certain L-histidine antagonists. The resistant plasmid confers the properties of the mutant strain upon the recipient Bacillus subtilis to make its high yield of product even higher.
