摘要
Abstract
The experiment was conducted to study the resistance to temperature(55 and 65 ℃ ), acid(pH value 1. O, 2.0 and 3.0), bile salt(0.1% and 0.3 % ), trace element copper(0, 10,50 and 250 mg/L) and zinc(0,120,600 and 3 000 rag/L)of several lactobacilli. The results showed that different lactobacil- lus had different resistance to stress factors: propagation, acid production and the resistance to acid and temperature(55 ℃ )of lactobacillus LGG were better than those of the other lactobacilli, but the survival rate of LGG under the temperature 65 ℃ was very low; lactobacillus ZJ614 resisted temperature(65 ℃ ) very strongly, but its propagation was negatively affected by CuE+ (50 mg/L) ; lactobacillus ZJ621 resisted acid more strongly, but resisted bile salt more weakly. Based on all-round analyses of the resistance to various stress factors of several lactobacilli, it was concluded that comprehensive resistance to stress fac- tors of lactobacilli ZJ610 and ZJ617 were more strong.关键词
