Isolation and Characterization of Bacillus thuringiensis from Fresh Water
Five Bacillus thuringiensis isolates were recovered from 30 samples of fresh water collected from Wuyi Mountain and the Forest Park of Fuzhou.To learn more about the characteristics of these novel isolates,phase-contrast microscopy,physiology and biochemistry,protein,bioassay for Aedes albopictus and Helicoverpa armigera were performed.LLW1 was found to be toxic against the A.albopictus,with the correction mortality of 95.5%.And cyt2 was detected in the novel strain.However,no strain toxic against H.armigera was found in this study.
