Effect of the bioaugmentation in the heavy oily sludge degradation. a Bacterial consortia, and b bacteria and fungi consortium. The degradation of TPH (%) is shown next to each treatment. Error bars represent standard deviation of six replicates. C1 soil, sawdust, and inorganic nutrients, E1 with enrichment culture, E2 with bacterial consortium from USBA collection, E3 with bacterial consortium from enrichment cultures. D1 soil, rice husks, sugarcane bagasse, and inorganic nutrients, F1 with enrichment culture, F2 with bacterial consortium, F3 with fungal consortium, F4 mix F1 and F3, F5 mix F2 and F3
