In contrast to the current view that psychrophily combined with an absolute requirement for NaCl is connected with the Gram-negative cell wall type, psychrophilic and psychrotolerant, NaCl-requiring, Gram-positive bacteria have been isolated from tropical Atlantic, Arctic and Antarctic deep-sea sediments. Some of the isolates are even extremely psychrophilic, having maximum growth temperatures of 4 degrees C. On the basis of phenotypic characteristics, DNA base analyses, DNA-DNA hybridizations and partial and complete 16S rRNA gene sequence analyses, the strains from the three distinct geographical regions have been allocated to the obligately marine species Bacillus marinus. The distribution and origin of B. marinus are discussed and an emended description of the species is presented.
与当前认为嗜冷性与对氯化钠的绝对需求相结合与革兰氏阴性细胞壁类型相关的观点相反,已从热带大西洋、北极和南极深海沉积物中分离出嗜冷和耐冷、需要氯化钠的革兰氏阳性细菌。其中一些分离株甚至是极端嗜冷菌,最高生长温度为4摄氏度。根据表型特征、DNA碱基分析、DNA-DNA杂交以及部分和完整的16S rRNA基因序列分析,来自三个不同地理区域的菌株已被归类为专性海洋物种海芽孢杆菌。讨论了海芽孢杆菌的分布和起源,并给出了该物种的修订描述。
