Study of the Population Structure of Bacillus Species Isolated from Medicinal Plant Selfheal and Its Rhizosphere Soil

Bacillus is widespread around the world and mainly found in the soil and on the surface of plants and animals.We obtained 27 Bacillus isolates from selfheal and its rhizosphere soil using dilution plating technique in Wuyi mountain and then identified these strains by 16S rDNA sequencing to know the diversity of Bacillus inside the selfheal and its rhizosphere soil and enrich Bacillus distribution.Our results showed that 27 strains were classified into 14 Bacillus species and two strains may be new Bacillus species,suggesting that there was a diversity of Bacillus species in selfheal and its rhizosphere soil,and it enriched the study of the endogenous Bacillus in the medicinal plant.
