Optimization of Solid Fermentation Process of Bacillus megaterium and Its Application in Crop Growth

摘要

In this study, the cassava residue was identified as the solid fermentation medium of B. megaterium by the culture medium optimization experiment. Determined cassava residue as substrate, 5% glucose, 10% com syrup, initial pH 6.5-7.0, 40% initial moisture, 37 °C was the finally optimum condition of solid fermentation of B. megaterium through single factor experiment and orthogonal experiment. The pepper field experiment shows that the bacterial fertilizer improved pepper yield per plant, fruit weight, flesh thickness, fruit length, fruit width by 14.71, 9.47, 13.22, 3.40, 25.91% respectively and has a good application value.
