The significative 2 strains were classified according toculture characteristics, modality characteristics, characteristic reaction, and comparing16S rRNA gene sequence with other 5 strians.

The 16S rRNA gene sequence of the two isolates were amplified and compared with those of other Streptococcus retrieved from GenBank.

Method: Based on Physiological and biochemical experiments and the analysis of 16S rRNA sequence.

Application of identification of atypical strains with 16S rRNA gene sequence analysis;

Evaluation of 16S rRNA gene clone library in analyzing bacterial flora by mixed bacterial suspension;

16S rRNA gene clone library technique for analysis of flora distribution in fecal samples from diarrhea patients;

Cloning and phylogenetic analysis of 16S rRNA gene of E. wenyoni in cow

But there is little literature on gene sequencing,especially on 16S rRNA gene and cpcHID operon sequences analysis about genetic relationship of 5 samples of Arthrospira.

5 kb fragment of 16S rRNA gene, a 800bp fragment of elongation factor gene and a 1.

SBR was used to strengthen the domestication of activated sludge bacteria which has a certain function in the degradation of marine water-based drilling fluid,and 16S rRNA gene library analysis method was used to analyze the bacterial community structure.
