摘　　要：从酸败的马鹿初乳中分离得到49株菌株,经革兰氏染色和接触酶试验及生理生化试验共计鉴定出12种乳酸菌,这些乳酸菌以中温型乳酸菌为优势菌。为鉴定马鹿初乳中乳酸菌对机体的适应能力,对这12种乳酸菌进行耐性试验,主要验证其对人工胃液、人工肠液的耐受性,结果表明其中的4株乳酸菌耐酸性较强,以13号菌耐酸性最强,这将为未来开发鹿乳酸奶提供可靠地理论依据。49 bacterial strain was obtained from the lactic acid bacteria of rancid colostrum from Cervus elaphus and 12 of them was identified as lactobacillus by means of gram staining and enzyme contact test and the type of which is intermediate temperature. The tolerance experiment of the 12 strains of lactic acid bacteria was carried out to identify the adaptive capacity to the organism including the tolerance to the simulatedgastricfluid and the simulatedintestinalfluid. The resistance of 4 lactic acid bacteria of them to acid are stronger than the others and the No. 13 is the strongest based on the results. These results will offer a reliable theoretical basis for the development of the Cervus elaphus yoghourt.
