摘要
从含酒石酸的环境中分离得到10株可降解酒石酸的菌株,通过测定各菌株对酒石酸的降解率,从中筛选得到一株降解率高达70%的菌株,命名为F1。依据微生物学分类鉴定方法,对该菌株进行形态学、生理生化特性鉴定及rDNA-ITS序列分析,鉴定该菌株为黑曲霉(Aspergillus niger)。经毒素检测和动物毒性实验未见毒性。
Ten strains which can degrade tartaric acid were isolated from tartaric acid rich environment. Strain F1 of degradation rate up to 70% was screened out. Ft was identified as AspergiUus niger based on its morphological, biochemical properties, and rDNA-ITS sequence analysis. Strain F1 did not show any toxicity in toxin determination and animal toxicity experiment.
