中文摘要: 利用碳酸钙平板法从藏灵菇菌块为发酵剂制备的发酵酸乳中分离到 2 株产酸细菌， 对其进行形态、 生理生 化测定及 16S rRNA 序列分析。结果表明，发酵凝乳中的这两株优势乳酸菌是乳酸乳球菌乳酸亚种。本研究结果为开 发稳定的优良发酵剂提供菌种资源，并为进一步研究藏灵菇酸奶的保健功能奠定基础。
Abstract:Two acid-producing bacteria were isolated from the yogurt prepared by fermentation agents of Ti－ betan kefir using calcium carbonate plate method. These two isolates were identified as Lactococcus lactis subsp. lactis based on the characterization of morphology， physiology and biochemistry， and 16S rRNA sequence analysis. The present research provide strain resources for fermentation agents， and also lay a foundation for fur－ ther studying on health function of Tibetan kefir yogurt.
