摘　　要：从青岛东风盐场分离到3株嗜盐古细菌（编号：ZDA－1，ZDA－2和ZDA－5），细胞为多形态杆状（0．7～15μm×2．0～50μm），最适生长NaCl浓度为3．4mol／L，含有甘油二醚脂，类胡萝卜素色素和极性脂TGD－2（三糖基二醚脂），x（C＋C）分别为63．7％，62．7％，和64．3％，据此，这3株菌可归入嗜盐小盒苗属（Hchoarcula）；但它们不水解淀粉，明胶不液化，不水解酪蛋白等生理生化特性不同于该属中现已正式承认的两个种，因此，本工作分离的3株菌可能是嗜盐小盒菌属一个新种.The Strains of extremely halophilic bacteria (No. ZDA-1, ZDA-2 and ZDA-5) were isolated fromDongfeng Solar Salt field of Qingdao. These isolates are pleomorphic rod shaped (0. 7 ~ 1. 5 μm × 2. 0 ~ 5. 0μm). Their optimal growth occurs in the presence of 3 .4 mol/L concentration of NaCl. Diglycosyl diether andC50 carotenoids are present in the cell. The POlar lipid composition TGD contained in the organisms is characterized by representives of the genus Haloarcula . x (G + C) contents of DNA are 63 .7%, 62 .7% and 64 .3 %,respectively. The strains belong to Halearcula and differ from the previously described species in physiologicaland biochemical features. These strains probably represent a new species.
