Efficient degradation of dibutyl phthalate and utilization of Phthalic Acid Esters (PAEs) by Acinetobacter species isolated from MSW (Municipal Solid Waste) leachate


Maitra S.S. et al. View all

Solid Waste Management

Bacteria from the genus Acinetobacter are opportunistic pathogens and cause harm to humans. In this study a new bacterial strain designated as Acinetobacter sp. 33F was isolated from municipal solid waste (MSW) leachate. This bacterium is useful as it degrades and utilizes dibutyl phthalate (DBP) as...
