The taxonomy identification of the screened biocontrol bacteria
has increasingly come to rely on molecular biological methods. 16S
rRNA sequencing is used widely as an alternative method to identify
microbial organism, but it is not applicable for some Bacillus species
with high pairwise 16S rRNA similarity values. Some genes like
gyrA, gyrB, polC and rpoB have been proposed to provide conclusive
evidence on the evolutionary relationships of B. subtilis and related
taxa
