| Abstract | The contamination and distribution of phthalate esters - synthetic compounds widely used in plastic product production, including food and medical packaging - has raised safety concerns due to their endocrine-disrupting activity and mandated to be treated. Bacillus subtilis strain 3C3, isolated as an organic-solvent-tolerant bacterium, was capable of utilizing diethyl phthalate as a sole carbon source. Biodegradation of diethyl phthalate occurred constitutively without lag period, and its kinetics followed a first-order model. The biodegradability was significantly enhanced with the supplementation of yeast extract as a co-metabolic substrate. In the presence of Tween-80 as a solubilizing agent, cells rapidly degrade a range of short-chain phthalate esters at high concentrations (up to 1000 mg l super(-1 for diethyl phthalate). The biodegradation of short-chain phthalates in the binary, ternary and quaternary substrate system revealed that the coexistence of other short-chain phthalates had no significant influence on the biodegradation of diethyl phthalate, and vice versa. These results substantiated that B. subtilis strain 3C3 has potential application as a bioaugmented bacterial culture for bioremediation of phthalates.) |
