  Rezumat:  The genus Bacillus, belongs to phylum Firmicutes, family Bacillaceae and represents a large group of rod-shaped, aerobic or facultatively anaerobic, Gram-stain-positive and endospore-forming bacteria with low DNA G+C content (32–66 mol%) (Logan & De Vos, 2009). Fujian Province has the longest coastal length in China. The aim of this study was to understand the diversity of halotolerant and halophilic Bacillus-like species in salinity tolerance environment of Fujian Province. The Bacillus-like bacteria were isolated from soils from saline enviroment in Fujian Province by culturomics and preliminarily identified based on the 16S rRNA gene sequences. Seventy-six isolates were obtained from 43 soil samples, and identified as 12 species belonging to 4 genera. The plate counts range of Bacillus-like species was 0.50-1.26×103 cfu·g-1. Based on their occurrence frequency, the Bacillus-like species were discriminated as the high frequency species middle frequency species and low frequency species (other six species). Through the NaCl tolerance experiment, 64.4% strains were grouped into the halotolerant bacteria, and 35.6% strains were moderate halophiles. Therefore, there were many Bacillus-like species with high halotolerant ability, which provide rich resources and theoretical basis for exploring and utilization of functional strains.

Keywords：Bacillus-like species, halotolerant and halophilic, community.
