摘要
从南京地区土壤中分离到一株产抗氧化功能胞外多糖的细菌菌株JS-1.菌株JS-1的生长范围较宽,中性至碱性环境,以及25-30℃范围内均可正常生长,可利用蔗糖、葡萄糖、乳糖、甘露醇和麦芽糖作为碳源,能很好地利用有机氮和硝态氮.部分长度的16S rDNA序列分析及系统发育分析表明,菌株JS-1与Enterobacter属同源性为99%,最终将菌株JS-1鉴定为Enterobactersp..
A strain producing antioxidative exopolysaccharide named JS-1, has been isolated from the soil in Nanjing. The strain JS-1 could grow well in pH value from 6 to 11 and temperature from 25 ℃ to 30 ℃, and it could use sucrose, glucose, lactose, mannose and maltose as carbon source, organic N and nitrate N as N source. Strain JS-1 has been identified as Enterobacter sp. based on the phylogenetic analysis of partial 16Sr DNA sequences.
