Use of bacteria for the remediation of sites contaminated by petroleum hydrocarbons

Environmental problem

Environmental problem

habitat alteration

physical and chemical modification of the environment

danger due to toxicity levels

Methodology used

inoculation of bacterial consortia

inoculation of bacterial consortia

different genera of bacteria

quantification of microbial parameters

formation of the degradation halo

colony growth

additional methods

Fluidized-bed bioreactor

Biosurfactants

Effective Adsorbents

There are bacteria that use oil as food and convert it into carbon dioxide and water, significantly reducing pollution in water sources and soils

the inoculation of bacteria had optimal growth and development under different conditions, showing that the degradability of toxic compounds is a fact in favor of this treatment.

Results

degradation of the pollutant

heavy metals

alkanes

attenuation of the pollutant in a certain period of time

viability

low cost

effective metabolic diversity
