Identification and primary application of TSNA degrading bacterial strain AS97 isolated from aging tobacco leaves
一株源于醇化烟叶表面高效降解TSNA 菌株AS97 的分离筛选、鉴定及应用

Objective] The purpose of this work was to screen strains having tobacco-specific nitrosamines(TSNA) deteriorating activity,isolated from the inner and superficial of tobacco plants.Then strain AS97 was isolated and identified for further application.Methods] Strain AS97,with the highest conversion ability against both nitrate and nitrite,was screened by enrichment and selective medium.The strain was identified by morphological,physio-biochemical characteristics and 16S rRNA gene sequence analysis.The con...
