preparation example Construction
[0057] This embodiment provides a series of preparation methods for composite immobilized bacterial agents, wherein the preparation method includes the following specific steps:
[0058] 1) Screening of high-efficiency petroleum hydrocarbon-degrading bacteria: Screen high-efficiency petroleum-degrading bacteria from aged oil sludge and oil-contaminated soil. Dissolve 10 g of oil sludge and soil in inorganic salt medium, place them in a shaker, and heat them at 30 ° C. After subculture for 7 days, take 10 mL of the enrichment solution in the inorganic salt medium, and repeat the above steps 4 times. High-efficiency petroleum hydrocarbon degrading bacteria were obtained after domestication. Take a small amount of bacterial liquid and apply it on the LB medium for streaking and purification. After obtaining pure bacteria, use 20v% glycerin aqueous solution (wherein the volume fraction is calculated based on the total volume of glycerin aqueous solution) and store at -20°C;
