Abstract
Taking the naturally fermented pickled jerusalem artichoke in Meishan area and Guang'an area as the objects,the strains in the fermented pickled jerusalem artichoke were screened,identified and evaluated.A total of 87 strains of bacteria were isolated from the fermented pickled jerusalem artichoke in the two regions.Following preliminary screening using simulated gastric juice,8 strains of bacteria with good tolerance to gastric conditions were identified,consisting of 2 strains of Lactobacillus paracasei,4 strains of Lactobacillus plantarum,and 2 strains of Lactobacillus brevis,respectively,and none of them had hemolytic activity.These 8 strains demonstrated good growth performance between 25-35℃,in which strain M24(Lactobacillus plantarum)exhibited good salt tolerance,hydrophobicity and self-aggregation ability,strain M20(Lactobacillus plantarum)showed excellent nitrite resistance and acid resistance,strain M2(Lactobacillus brevis)showed good acid production capacity,and strain G34(Lactobacillus paracasei)had notable hydrophobicity.关键词
