| Abstract: | Sewage from different brewery working procedure was provided as media to cultivate Bacillus thuringiensis(Bt).The chemical oxygen demand(COD),pH,parameters of fermentation,and toxicity of sewage from urban sewage-digestive plant and brewery wastewater-digestive plant were investigated.It was showed that brewery wastewater/acidified wastewater+sludge was suitable media,which could produce 109 cfu·mL-1 spores.Compared to urban wastewater+sludge materials(D595 nm=0.202),it had higher crystal compound(D595 nm=0.209) and shorter fermentation cycle with 18-22.5 h.It would be good material for Bt biopesticide production. |
