PROCESS FOR CULTIVATING BACILLUS THURINGIENSIS BIOPESTICIDES IN WASTEWATER TREATMENT SLUDGES
摘要
Disclosed herein is a process for preparing a Bacillus thuringiensis bio-insecticide, the process comprising the steps of: (a) inoculating wastewater treatment plant sludge(s) with Bacillus thuringiensis bacteria; (b) aerobically cultivating the bacteria in the sludge(s) for a period of time sufficient for producing the bio-insecticide resulting from the sporulation of the bacteria through synthesis of insecticidal delta -endotoxin proteins in the form of parasporal crystals; (c) recovering the sludge(s) containing the resulting bio-insecticide.
