Bisphneol A Biodegradation Costal sediments Labrenzia sp. YY-1
Bisphneol A [BPA; 2.2-bis(4-hydroxyphenyl) propane] is an endocrine-disruptor. The degradation of BPA was studied on coastal sediments, and a BPA-degrading bacterium was isolated. BPA was degraded during 1 week incubation by bacterial population in the coastal sediment. The most probable numbers (MPN) of BPA-degrading bacteria ranged from <0.3 to 2.3 cells/g wet of coastal sediments. A BPA-degrading bacterium, strain YY-1, was isolated from coastal sediments. Although the bacterium did not utilize BPA as the sole carbon source, YY-1 degraded BPA for 1 week in addition of peptone and yeast extract, or sterilized coastal sediments. The strain YY-1 was an aerobic, short rod shape, motive, Gram-negative bacterium, and the nucleotide sequence of 16S rRNA gene was close to that of Labrenzia aggregata.
