Abstract

The diversity of bacteria was explored in two different environments in Brazzaville: soil and fermented peppers. The count showed that the total flora is greater in the fermented pepper (9.4. 104 CFU/g) than in the soil of 3.7. CFU/g, bacteria of the Bacillus genus are numerically more important in soil (9.3.104 CFU/g) than in fermented pepper (7.7.104 CFU/g). The morphotypes of all isolates presented small, medium and pink and whitish colored colonies, are catalases positive, protease producers, Gram positive, and spore forming, including one Gram negative isolate. 16S rDNA PCR of the isolates, Agarose Gel electrophoresis, sequencing and in silico analysis of the sequences were performed. The amplicons showed sizes closed to 1500bp, BLASTn analysis of the sequences made it possible to identify Twenty (20) strains, with a predominance Bacillus cereus sensu stricto strains (40%). Taking by environment, six (6) in the soil, namely Bacillus cereus sensu stricto (16.66%), Bacillus thuringiensis (16.66%), Bacillus anthracis (16.66%), Bacillus welmani (16.66%) and a Bacillus albus (16.66%), fourteen (14) strains in fermented peppers namely: Bacillus cereus sensu stricto (21.42%), Bacillus thuringiensis (7.14%), two Pseudomonas sp, Bacillus thuringiensis (3.57%), Bacillus sp (3.57%), Bacillus albus (1), Lysinibacillus sp (3.57%), uncultured (3.57%). All strains produce the proteolytic enzyme with diameters ranging of more than two cm. The phylogenetic inference using 16S rDNA analysis shows that these bacteria are very closed, excepted the Pseudomonas sp and uncultured bacteria, all belong to Bacillus cereus group, forming a coherent taxonomic group.
