Review summarizes bioremediation strategies using biochar for soil cleanup, highlighting strengths and challenges.
This review summarizes current data on the use of biochar for the reclamation of soils contaminated with petroleum hydrocarbons. The main focus is on the role of biochar in implementing two bioremediation strategies: bioaugmentation involving the introduction of specialized hydrocarbon-degrading microorganisms, and biostimulation aimed at activating indigenous microflora. Special attention is given to the promising technology of using biochar as a carrier for immobilizing specialized hydrocarbon-oxidizing microorganisms, which enhances the efficiency of petroleum hydrocarbon cleanup. Along with the advantages, the review discusses limitations that restrict the widespread practical application of biochar in oil-contaminated soils.
