【摘要】 [目的]筛选出高效除臭菌株,为生活垃圾生物除臭提供菌种资源。[方法]采用初筛与复筛相结合的方法,分离高效除臭乳酸菌,并对其进行菌落及菌体形态学观察、生理生化特征及16S rDNA序列分析。[结果]从生活垃圾中分离获得一株高效除臭乳酸菌LDJ,经鉴定为干酪乳杆菌。[结论]该乳酸菌在实验室条件下24 h内对氨的去除率为90%,48 h内对硫化氢的去除率为46.8%,可较好地去除垃圾恶臭味。更多还原

【Abstract】 [Objective] In order to offer strain resources for biological deodorization of garbage,highly deodorant strains were screened.[Method] The highly efficient deodorant lactic acid bacterium was separated with screening and rescreening method.Its morphology,physiology,bio-chemical and molecular characteristics were studied.[Result] A special strain LDJ was screened from domestic refuse which was identified as Lactobacillus casei.[Conclusion] LDJ can decrease 90% of NH3 emission from garbage in 24 h and decrease 46.8% of H2S in 48 h,which has an obvious deodorant effect.更多还原
