【 摘 要 】

With the improvement of people's living standards, the pollution caused by oil-rich kitchen wastewater has attracted people's attention. In order to screen efficient soybean oil-degrading bacteria, six strains that could degrade soybean oil were isolated from the soil with soybean oil as the sole substrate. Among them, the strain CR5 and CR6 had strong ability to degrade soybean oil. After 10 days of culture, the degradation rates of strain CR5 (pH 2.42) and CR6 (pH 3.84) on soybean oil were 65.25%, 66.04% respectively. In order to study the salt tolerance of the strains, the degradation rates of soybean oil by CR5 were 16.36%, 3.85% and 7.36% after 5 days of cultivation at different salt concentrations (1.0%, 1.5%, 3.5%) and those of CR6 were 5.52%, 8.45%, 16.98%.
