贵州侗族酸肉中一株抗氧化弯曲乳杆菌LAB26的鉴定及特性

摘要

A strain of lactic acid bacteria was selected from sour meat of the Dong ethnic minority in Guizhou, China. Its DPPH and hydroxyl radical scavenging activities, reducing power and anti-lipid peroxidation activity were (59.67 ± 6.68)%, (153.17 ± 5.50)%, (47.31 ± 4.62)%and (55.00 ± 5.19)%, respectively. Moreover, the strain had good tolerance to NaCl and NaNO2.%从贵州侗族酸肉中筛选出一株乳酸菌，其DPPH自由基清除率、羟自由基清除率、还原能力、抗脂质过氧化能力分别为（59.67±6.68）%、（153.17±5.50）%、（47.31±4.62）%、（55.00±5.19）%，并且菌株有良好耐受NaCl和NaNO2的性能。
