Study on the Building Mechanism of Straw Immobilized Microorganisms

Abstract

Abstract-Using the single hydrocarbon degrading bacteria, two kinds of straw materials called MG and SY as the carrier, and then preparing two kinds of immobilized microbs by adsorption, examining their strain absorption rate and petroleum hydrocarbon degradation rate after 7 days. Characterizing the morphology of straw carrier material and immobilized microbs before and after the degradation of oil by SEM and BET. The results showed that ： strain absorption rate of immobilized bacterial immobilized by SY and the petroleum hydrocarbon degradation rate after 7 days is higher than MG. Straw SY is a desired carrier material, because of its high surface roughness, specific surface area, mechanical strength and stable structure is better.
