Use of bacteria for the remediation of sites contaminated by petroleum hydrocarbons
Environmental problem
habitat alteration
physical and chemical modification of the environment
danger due to toxicity levels
Methodology used
inoculation of bacterial consortia
different genera of bacteria
P. Aeruginosa
Bacillus
Mojavensis
Sphingomonas
Aeribacillus
quantification of microbial parameters
formation of the degradation halo
colony growth
additional methods
Fluidized-bed bioreactor
Biosurfactants
Effective Adsorbents
Biostimulation
bioaugmentation
Phytoremediation
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
