The Role of Biodegrading-bacteria to Remove Bisphenol-A from Polluted Soils

Background: Bisphenol A (BPA), is an organic component, functions as an endocrine disruptor (EDC). It ubiquitously exists in both, the environment and the food sources, leading to continuous and unintentional exposure among populations of human and animal.

Aim of the Study: Investigate biodegradation activity of BPA by bacteria isolated from polluted soil with plastic wastes.

Materials and Methods: 50 samples were taken from polluted soil with plastic wastes of different sites in Kerbala province; minimal salt media (MSM) were used to identify the capability of the isolates to bioremediate 200 mg/L, as a final concentration of BPA by using HPLC analysis.

Results: the bacterial isolates could degrade the BPA in different ranges started from 18.7% to 99.9%. the recent study found that, Serratia plymuthica, Pantoea spp, Shingomonas paucimobilis, Pseudomonas aeruginosa and Bacillus spp. were more efficient in BPA biodegradation than Acinetobacter haemolyticus, Acinetobacter lwoffii, Escherichia coli and Proteus spp.

Conclusion: Many types of bacterial isolates could convert the toxic organic compound Bisphenol A to another metabolites and according to recent study we could employee these activity to eliminate these materials safely from the polluted soils and water efficiently than using chemicals that might be toxic to environment, human being and animals.
