【摘要】 从几种泡菜中分离出86株菌,对其在适温和低温下产酸速率及硝酸盐降解能力进行测定,筛选出5株产酸速率快、硝酸盐降解能力强的菌株。经形态学鉴定及生理生化反应试验,初步鉴定为:植物乳杆菌2株,短乳杆菌1株,戊糖乳杆菌1株,肠膜明串珠菌葡聚糖亚种1株,并对5株菌的发酵性能进行了测定。更多还原

【Abstract】 Eighty-six strains of lactic acid producing bacteria were isolated and identified from many sorts of pickling vegetables.Five strains with excellent characteristics in acid production and the ability for the nitrate degradation were selected.By morphology appraisement and the test for physiology and biochemical event,there are two Lactobacillus plantarum,one Lactobacillus brevis,one Lactobacillus pentosus,one Leuconostoc mesenteroides subsp.dextrainicum.The fermentation characteristics of these five strains were also studied.更多还原
