重离子诱变选育聚β-羟基丁酸酯高产菌株研究
Studies on Selecting High-yield Poly-β-hydroxybutyrate Producing Strain by Heavy-ion Irradiation
摘要
Abstract
As a new biodegradable polymer materials, Poly-|J-riydroxybutyrate ( PHB) has attracted wide attention from people day by day. This study adopts heavy-ion mutation breeding technology, using I2C ion beams to mutate the PHB producing Strain-Bacillus Z-3, then screen a PHB high yielding strain Al 1 from a mount of mutant strains. Its PHB output can reach 1.404 g/L. This is 1. 33 times as compared with the original strain. The results indicate that heavy-ion mutation breeding technology has good mutagenic effects. It is an effective method and way to microbial mutation breeding.关键词
