Growth and acid-production ability of lactic acid bacteria from traditional sausages in Inner Mongolia

Growth ability in different temperature,different pH and acid-production ability in different culture medium of 8 lactic acid bacteria strains,which were isolated from traditional sausages in Inner Mongolia,were studied.The results indicated that 8 lactic acid bacteria stains could grow in different temperature and different pH condition,especially in 30℃ and pH 6.5.8 lactic acid bacteria strains almost had the same acid-production ability in different culture medium from 1d to 13d,the pH were all below 4.2 after 24h and kept stable.
