Preparation of a gel-type microbial-missile for biodegradation of oil pollution

Abstract

Abstract The removal of oil spill pollution is a global problem. In order to solve the problem of low biodegradation efficiency, a series of microbial-missile materials with high floatability, hydrophobicity and biological affinity were prepared to enhance the degradation of oil spill. Hydrophobic macroporous materials with polar groups inside and hydrophobic aliphatic polyester outside were prepared by physical and chemical methods using SA/PVA as substrate for gel-type microbial-missile. The experimental results show that the saturated adsorption rate of macroporous gel-type microbial-missile to oil particles is as high as 18.17 g/g, the contact angle is 149.300°, the average density is 0.5883 g/cm3, the average mechanical strength is 2.52 mN, the penetration rate of 40 s is 82.72%, and the degradation rate of crude oil in 7 days is 88.95%.
