硝磺草酮降解菌 HZ-2制剂固定化载体材料性能的比较
Pexformance comparison of different carrier materials for immobilization of mesotrione-degrading strain HZ-2
摘要
Abstract
Objective] To evaluate the effect of modified bagasse (MSB, MSB-Mo and MSB-CI) on the immobilization of mesotrione-degrading bacteria strain HZ-2 .[Method]Three types of modified bagasse and activated carbon were selected as the carrier candidates for the bacterial immobilization , and the deg-radation abilities of immobilized composites were examined .[Result]After 48 hours culture , the high D600 nm values indicated that modified bagasse ( MSB, MSB-Mo and MSB-CI ) and activated carbon had strong abilities to immobilize bacteria .More than 85%of mesotrione in LB medium was degraded using modified bagasse as a carrier after 3 days of culture , which was higher than the results of activated car-bon .MSB-Mo composite had the best degradation performance with a degradation rate of 96.35%.More-over ,mesotrione in soil was degraded over 99%after 7 days by adding glucose as support nutrient to the modified bagasse .[Conclusion] Modified bagassse MSB-Mo is the most available carrier material , which demonstrates the highest potential of being a new biological carrier material for immobilization of mesotri -one-degrading bacteria strain .关键词
