Abstract
A novel marine microorganism (Pseudomonas CH07) capable of degrading different congeners namely coplanar, sterically hindered and other chlorobiphenyls present in a technical grade PCBs (Clophen A-50); the aerobic bacterial strain, identified as Pseudomonas CH07 isolated from coastal zone of Arabian sea near Goa, India subjected to intense anthropogenic activity is shown to degrade PCBs of chlorine content (4-7 chlorine atoms per biphenyl).
