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

Samples

amounts of soil with concentrated hydrocarbons

bacteria isolated from contaminated soils

Gram -

Gram +

variety of aromatic hydrocarbons in bacterial communities

Results

viability

effective metabolic diversity

low cost

attenuation of the pollutant in a certain period of time

degradation of the pollutant

alkanes

heavy metals

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.

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

Methodology used

additional methods

Effective Adsorbents

Biosurfactants

Fluidized-bed bioreactor

inoculation of bacterial consortia

quantification of microbial parameters

colony growth

formation of the degradation halo

different genera of bacteria

Environmental problem

danger due to toxicity levels

physical and chemical modification of the environment

habitat alteration
