Abstract:
1. A method for bioremediation of highly aromatic hydrocarbon waste, comprising: a) preparing a microbial blend capable of degrading aromatic hydrocarbons wherein microorganisms in the microbial blend are adsorbed on a biodegradable carrier; b) preparing a biopile comprising a mixture of the hydrocarbon waste, soil and a bulking agent, wherein the highly aromatic hydrocarbon waste has an aromatics content of 100% w/w; c) adding the microbial blend into the biopile followed with addition of nutrients to promote bioremediation reaction; and d) maintaining aeration and moisture of the biopile for a time sufficient to complete the bioremediation of the highly aromatic hydrocarbon waste, wherein the bacteria of the microbial blend are
