Bioremediation of soil polluted with oil

Abstract

Microplastics have reached all corners of our planet, including soil and water. Plastic-degrading bacteria are seen as a promising, environmentally friendly tool for the bioremediation of soil polluted with microplastics. The petroleum origin of plastics makes them candidates for bioremediation analogous to the bioremediation of soil polluted with oil and its derivatives. A mud pit, located near the village of Turija, used for mud formation for the lubrication of drill pipes for drilling rigs, ended up polluted with oil and its derivatives. It was bioremediated using the in situ procedure. The content of n-hexane extractable substance, total petroleum hydrocarbon, dry substance, and loss on ignition were analyzed.
