In an attempt to isolate indigenous marine myxobacteria from coastal samples, we obtained two swarm forming bacteria. Both isolates formed cell aggregates which, at least in one isolate, developed to fruiting body-like structures consisting of a mass of myxospore-like cells. The optimum NaCl concentrations for their growth were between 2 and 3%, comparable to the NaCl concentration of seawater. This growth characteristic strongly suggests that the two isolates are specific marine bacteria. The 16S rDNA sequence studies indicated that the two isolates were related to the genus Nannocystis. Based on the phylogenetic distances between branches, we concluded that the isolates should be assigned to two new myxobacterial genera.
为了从沿海样本中分离本土海洋粘细菌，我们获得了两种能形成菌落的细菌。两种分离株均形成细胞聚集体，至少在其中一种分离株中，这些聚集体发育成类似子实体的结构，由大量类似粘孢子的细胞组成。它们生长的最佳NaCl浓度在2%至3%之间，与海水的NaCl浓度相当。这种生长特性强烈表明这两种分离株是特定的海洋细菌。16S rDNA序列研究表明，这两种分离株与囊球菌属有关。根据分支之间的系统发育距离，我们得出结论，这些分离株应归为两个新的粘细菌属。
