Abstract

Members belonging to the genus Brevibacillus had potentials in the bioremediation of hydrocarbon-contaminated soils. However, little is known about the fermentation medium and culture conditions of Brevibacillus panacihumi. The effect of concentrations of glucose and (NH4)2SO4, initial pH value and culture temperature on the biomass of B. panacihumi W25 was measured with single factor experiments, which was a hydrocarbon-degrading bacterium. Polynomial regression analysis showed optimal concentration of glucose and (NH4)2SO4, initial pH value and culture temperature were 45.2 g/L, 0.6 g/L, pH 7.3 and 30.3°C, respectively. The optimization of fermentation of B. panacihumi was reported for the first time.
