Hydroxylations of Biphenyl by Fungi [PDF]

Journal of Applied Bacteriology, 1980
Sixty‐six species of fungi were screened for their ability to hydroxylate biphenyl. Thin‐layer and gas chromatographic analyses indicated that seven organisms actively hydroxylated this substrate. Of particular interest were Cunninghamella echinulata ATCC 9244 which produced 4‐hydroxybiphenyl

Low Dose Organochlorine Pesticides and Polychlorinated Biphenyls Predict Obesity, Dyslipidemia, and Insulin Resistance among People Free of Diabetes

PLoS ONE, 2011
Background There is emerging evidence that background exposure to persistent organic pollutants (POPs) are important in the development of conditions predisposing to diabetes as well as of type 2 diabetes itself.

A practical approach to the degradation of polychlorinated biphenyls in transformer oil

, 2005
A practical and efficient disposal method for hydrodechlormation of polychlorinated biphenyls (PCBs) in transformer oil is reported. Transformer oil containing PCBs was treated by nanometric sodium hydride (nano-NaH) and transition metal catalysts.
