Evaluation of the Bioremediation Potential and Antimicrobial Activity of <i>Pseudomonas</i> and Bacillus Bacteria Isolated from Landfills in Brazzaville, Congo

The pollution of ecosystems as a result urbanization, industrialization and poor agricultural practices is becoming increasingly alarming. This has major impact on health the economy. causes illness in humans animals, even at low levels exposure, leading to endocrine disorders, congenital malformations, cardiovascular disease, nervous system damage cancer. They are brake redevelopment because threats they pose, generally causing an anaerobic environment by blocking diffusion air into soil pores, thus affecting microbial communities living there preventing infiltration water necessary for plant growth. In ecosystem subjected various disturbances, changes can be observed structure function, including loss aesthetic values, biomass or productivity, species composition. These include altered composition, habitat loss, disruption food webs variations macro- micro-climatic environmental conditions. Respect concern today’s society. To remedy this, concept biological control was used alternative, with selection microorganisms bioremediator interest. Twenty (20) isolates, 10 (50%) from Pseudomonas genus Bacillus genus, were isolated landfills, identified tested assess their biofertilization (phosphate solubilization) depollution (hydrocarbon degradation) potential, inhibit growth certain microorganisms. results showed that all isolates solubilized inorganic phosphate, although this activity higher Bacillus. All inhibited pathogens included study, while only E. coli. With regard ability degrade hydrocarbons, these bacteria exponential kinetics presence gasoline. evolved function number days. obtained work leave no doubt capacity large scale biofertilizers restore integrity promote sustainable agriculture, but also biodepollutants purify ecosystems.
