Abstract
Herein, we reveal the alteration in phenol oxidase enzymes complex production from Azospirillum brasilense Sp245 omegon mutants with polar and lateral flagella dysfunction and from A. brasilense Sp7 phase variants with different plasmid composition. The enzymatic activities for various laccases, tyrosinases, Mnperoxidases, and lignin peroxidases as well as the isomorphic composition of intracellular laccases and tyrosinases were estimated for the studied variants and the parent strains. It was noted that various genetic events correlating with phenotypic heterogeneity in A. brasilense populations affect their phenol oxidase activity level.
