title: [Riboflavin auxotrophs of Escherichia coli].
abstract: Escherichia coli riboflavin auxotrophs having a different level of riboflavin requirement were isolated. This auxotrophic mutations are located near cysB93 and trpA62 markers. The complementary effect of Bacillus subtilis riboflavin operon linked with pPR1 hybrid plasmid with rib8-1 and rib1-1 mutations was obtained.
