Abstract


Plastic is a significant reason for Environmental Pollution. Major earth surfaces, sea waters are getting polluted day by day with accumulation of plastic as waste material from different sources which is a serious concern for human beings and different marine animals living in this world. A few stages happen in the plastic biodegradation process and could be distinguished by explicit phras-ing. Bio-weakening characterizes the activity of microbial networks and other decomposer life forms answerable for the physical and synthetic decay that brought about a shallow debasement that changes the mechanical, physical and substance properties of the plas-tic. Bio-discontinuity alludes to the reactant activities that separate polymeric plastics into oligomers, dimers or monomers by ecto-compounds or free-radicals discharged by microorganisms. Osmosis portrays to the incorporation of particles moved in the cytoplasm in the microbial digestion. Mineralisation alludes to the total corruption of atoms that brought about the discharge of totally oxidized metabolites (CO2, N2, CH4, H2O). The microbial species discovered related with the debasing materials were recognized as two Gram positive and five Gram negative microscopic organisms. The microbial species related with the polythene materials were recognized as Bacillus subtilis, Bacillus amylolyticus, Bacillus cereus, Pseudomonas species etc. of which Bacillus amylolyticus causes 30% degradation and Bacillus subtilis causes 20% average degradation in a month. In this review article different isolation and identification processes followed so far for these important categories of microbes have been discussed for general awareness of research in this field
