Biphenyl mass
WebPolychlorinated Biphenyls. Polychlorinated biphenyls (PCBs) are man-made organic chemicals that were used in many industrial and commercial applications due to their non-flammability, chemical stability, high boiling point, and electrical insulating properties. PCBs do not readily break down once they enter our environment and can cycle between ... WebJan 1, 2024 · Further, other three enzymes involved in biphenyl degradation were identified by peptide mass fingerprinting (PMF) method. Furthermore, enzyme analysis for two enzymes, BphC and catechol 2,3-dioxygenase in SK-2 was carried out. Based on these results biphenyl degradation pathway in the strain SK-2 was validated. 2. Experimental …
