“…Immobilized microorganism technique to spilled-oil treatment has many advantages while compared to conventional suspension biological treatment technique. This technique have high treatment efficiency, stable , easy for operation, large biomass, low production of sludge, good solid-liquid separation effect, and also can be purified and maintained dominant bacteria of high efficiency [3,4]. Therefore, immobilization technology was widely used in spilled-oil treatment, especially in specific spilled-oil treatment [5].…”

Abstract. This paper focused on research the dynamic adsorption capacity of immobilized microorganisms on diatomite-based carrier material. Several important parameters were studied, including different immobilization methods, pH value of cross linking agent, the influence on the physical properties and degradation effect of immobilized microspheres with various immobilization bacteria amount. The experimental results showed that direct immobilization method was better that of the other methods. After crosslinking at the temperature of 25 ˚C for 24 h, the best immobilization conditions were at pH 5-6 in the cross-linking agent solution. The volume ratio of immobilization bacteria liquid and gel solution was 1:5. The immobilization of inorganic salts could accelerate the recovery of the activity of immobilized microorganisms, and the surface structure of the microspheres was observed before and after degradation by SEM. The highest degradation rate could reach 40% for free M4, while 70% for immobilized M4, which increased oil degradation rate over 30%.
