Meanwhile, a new biger genetic group containing 6 cilicate sWains was formed, and it was different from the reference strains. The phylogenic tree of the representative sWains HLJ01 (GenBank accession EF031269) and HB 16 (GenBank accession EF031270) was constructed by analysis of the 16S rDNA full sequence, the results of analysis of 16S rDNA sequence revealed that swain HLJ01, HB 16 and Bacillus mucilaginosus and Bacillus edaphicus were located in the same phylogenic branch. HLJ01 and HB16 had high homology with Bacillus mucilaginosus in the phylogenic tree, but the 16S rDNA sequence of HLJ01 only has the identity of 96.7% with Bacillus mucilaginosus, and of HB16 has the identity of 95.5% with Bacillus mucilaginosus.

根据16S rDNA-RFLP聚类结果，选取供试硅酸盐细菌菌株HLJ01和HB16作为代表测定了其16S rDNA全序列，其Genbank序列登录号分别为EF031269和EF031270.16SrDNA序列分析表明：代表菌株HLJ01与HB16虽然与胶质芽胞杆菌位于同一个系统发育分支，但相似性分别只有96.7％、95.5％；与土壤芽孢杆菌的相似性则分别为94.6％和93.3％。
