Evaluation of Heavy Metal Tolerance Level of the Antarctic Bacterial Community in Biodegradation of Waste Canola Oil

Heavy metal contamination is accidentally becoming prevalent in Antarctica, one of the world’s most pristine regions. Anthropogenic as well natural causes can result heavy contamination. Each has a different toxic effect on various microorganisms and species, which interfere with other pollutant bioremediation processes. This study focused co-contaminant metals waste canola oil (WCO) biodegradation by BS14 bacterial community collected from Antarctic soil. The toxicity 1 ppm concentration to WCO-degrading bacteria was evaluated further analyzed using half maximal inhibition (IC50) effective (EC50) tests. results obtained indicated that Ag Hg significantly impeded growth degradation WCO, while interestingly, Cr, As, Pb had opposite effect. Meanwhile, Cd, Al, Zn, Ni, Co, Cu only slightly inhibited WCO biodegradation. IC50 values for were found be 0.47 0.54 ppm, respectively. well-tolerated induced degradation, resulting EC50 3.00, 23.80, 28.98 ability tolerate biodegrading low-temperature conditions successfully confirmed, crucial aspect due co-contamination occur simultaneously, at same time it applied metal-contaminated areas.
