Plastic is a broad name given to different polymers having high molecular weight
and that can be degraded by various processes. However, degradation by physical
and chemical means leads to innumerable environmental hazards. On the other
hand, degradation of plastics by microorganisms seems to be more effective,
considering their abundance in the environment, their specificity in attacking
plastics and has very less environmental hazards. This study introspected the
comparative extent of plastic biodegradation by employing one fungal species
(Aspergillus niger) and three bacterial species (Bacillus weihenstephanensis,
Burkholderia cepacia & Escherichia coli) which were isolated from hydrocarbon
enriched soil from Purba Medinipur, West Bengal. Amongst the isolates Bacillus
weihenstephanensis has been found to be a novel candidate having sound biodegradation potential.
