Abstract

The paper reports that penicillin-producing strains and lovastatin-producing strains were irradiated by UV and subsequently by laser (632.8 nm), and the reparation rate reached 297% and 264%. High-yield mutant was selected with improved potency of 24.5% and 30%, respectively; Gibberellin producing strains were treated with chemical agent LiCl, and then irradiated with 632.8 nm laser. One mutant with 189.6% increased potency was obtained. The experimental results indicated that using laser irradiation after UV or chemical agent mutation was a new useful method in breeding high-yield strains.
