Microbial degradation of Abamectin in soil

Abstract

Abstract: Incubation test on the degradation dynamics of Abamectin in soil showed that the half-life of its non-biodegradation plus microbial biodegradation,non-biodegradation,and microbial biodegradation was 34.8,277.3 and 49.9 d,respectively,and its degradation in soil was mostly by microbes.A dominant bacterium which could effectively degrade Abamectin was isolated from test soil,and identified as Stenotrophomonas maltrophilia by 16S rDNA.The crude enzyme extracted from the dominant bacteria had a Michaelis-Mentn's constant 6.78 nmol穖l^-1 and a maximum rate 81.5 nmol穖in -1穖g^-1.

Key words: Abamectin, Soil, Microbial degradation, Dominant bacteria, Crude enzyme
