Аннотация:It has been established that strain No.6 after lyophilization and storage has been moved to the
wild type both on the level of antibiotic activity and enzymatic activity. Variants No. 12 obtained by
stepwise, double UV-rays, retained the stability of the changed properties.
Conclusion: UV-rays are leading to the induction of biochemical activity in a population of
bacteriocin-producing lactococci.
