In this study, Bacillus thuringiensis (Bt) biopesticide was produced through different fermentation processes using food waste with different water contents. The semi-solid state sample with 75% water content presented the highest δ-endotoxin efficiency of 862 μg/mL. δ-endotoxin efficiency increased by 30.2% from that of the solid-state sample (50% water content) and 73.8% from that of the submerged sample (99% water content). Results confirmed that semi-solid state fermentation presents considerable advantages compared with other fermentation types (solid-state and submerged). The timing adjustment of pH and recycling fermentation effectively counteracted the inhibition of pH and product, thereby increasing δ- endotoxin efficiency to 1,648 and 2,478 μg/mL (accumulated value of all four fermentation loops), respectively. A δ- endotoxin slow-release formulation using polylactic acid as the carrier was also developed to effectively promote the stability of Bt biopesticide.

Based on type, the global bacterial biopesticides market is segmented into bacillus thuringiensis, bacillus subtilis, pseudomonas fluorescens, and other types. Based on mode of application and crop type, the market is segmented into seed treatment, foliar spray, and other applications, and grains and cereals, pulses and oilseeds, commercial crops, fruits and vegetables, and other crop types, respectively. Furthermore, based on geography, the market studied is segmented into North America, Europe, Asia-Pacific, South America, and Africa, primarily to cover the key trends in the major countries. 2ff7e9595c
