CHARACTERIZATION OF PRODUCING-BIOACTIVES COMPOUNDS BACTERIAL ISOLATES COLLECTED FROM SOIL AT BRAZZAVILLE

In the objective of understanding the microbial diversity of soil and the production of related bioactives compounds, an exploration of samples soil have been hold in Brazzaville, Republic of Congo. Four soil samples were collected in fours sites of Brazzaville has listed : at Faculty of Science of Marien NGOUABI University two sites 300m away (plantation soil and ordinary sol), at Massamba Debat stadium (landfill, soil) and at Bacongo district (garage soil). Temperature were ranged from 33 to 41and the pH of soils from 4,7 to 7.Enumeration of microrganismes vary from a group to another and from a category of soil for each site as followed the most important were groups Staphylococci, Bacillus, enterobacteria, pseudomonas, streptomyces, yeast, The quantity of microorganisms varies according to group or genus.
