摘　　要：从冬尖腌制品中分离到一株厌氧嗜盐菌（SEM），该菌为革兰氏阴性杆菌，大小为0．5×6.0μm，专性厌氧，不运动，不形成芽孢，生长需要8％～25％NaC1，最适生长盐浓度为12．50～17．50，能利用多种糖和醇，发酵葡萄糖产生丙酸和已酸。它应归属于严格厌氧嗜盐菌Haloanaerobe，但与已报道的几个种有较大差异，是否为新种，还有待于进一步研究。The strain SEM was isolated from Salted Dongjian, SEM is Gram-negative, obligate anaerobic and halophilic, rod, with the size of single cell of 0.5×6.0μm, and non-motil,non-sporeforming. Growth required 8%~25% NaCl with an optimum at 12.5%~17.5% NaCl,sugers and alcohols were utilized, the main products of glucose fermentation were propionate and caproic acid. SEM belong to haloanaerobe. SEM differs from several known species of haloanaerobe. It is probably a new species.
