| 摘 要： | 对从青岛附近海产品盐渍中分离得到的两个菌株——CM1和CM4进行了分析．结果表明CMl和CM4符合盐单胞菌属(Halomonas)的特征，但与几个典型的盐单胞菌属菌种有显著的差异，因而可能是该属的新种．通过对其表型和生长特征的分析发现，这两个菌株可能采用了不同的进化稳定对策以适应特殊的高盐环境，即CMl采用了K-对策；而CM4采用的是r-对策，从而将进化稳定对策拓展到了无性繁殖的微生物领域。

| Abstract: | Physiological and biochemical analysis of two Halomonas species CM1 and CM4,which were isolated from the salt of some sea products from Qingdao,was carried out and the results showed that the two strains possessed the features of the genus Halomonas, but some of them were not identical to those of the classical species of this genus,suggesting that they may be new species of this genus.Further comparison of the two strains showed that the two strains may use different evolution stability strategy(ESS) to adapt to their specially high NaCl concentration environment.That is to say,CM1 used K strategy while CM4 used r strategy and ESS was expanded to the asexual bacteria. |
