Efforts on isolation of native plastic adoring beneficial microorganism from landfills of three different geographical niches were carried out following testing of their ability to degrade biodegradable polyethylene in laboratory appraisal of identified native microorganisms; Aspergillus terreus Gr., Aspergillus wentii Gr., Emericella nidulans (Eidam), Pseudomonas sp. and Streptomyces sp., on different biodegradable polyethylene showed biodegradability in terms of weight loss of plastic in liquid with biofilm formation on plastic strips and it was also noticed that bacteria remained more active compared to fungi in biodegradation process. Amylase production by proven microorganisms showed that A. terreus produced maximum amylase followed by E. nidulans, A. wentii, Pseudomonas sp. and Streptomyces sp. Bio-efficacy of microorganisms against different BD PE in pots indicated that colonization of plastic was not found up to 3 month interval by all of them but E. nidulans found to colonizing IPCL plastic and A. wentii colonizing Israel plastic at 6 month interval.
