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
