Abstract:
It is well known that large quantities of non-recyclable plastic, namely low-density polyethylene (LDPE), represent a major pollution problem in the environment, thus a solution would be its degradation through the adhesion and accumulation of microorganisms’ consortia on the polyethylene surface. The microbial complexes that are involved in the decomposition of non-recyclable plastic were created in the polluted soil collected from the landfill situated near Slobozia-Dusca village. Analyzing the consortia of microorganisms obtained, which includes mycelial fungi and bacteria, we observed that the fungi are predominant, for the most part representatives of the Trichoderma spp., Penicillium spp., and Fusarium spp., while for bacteria only the genus Pseudomonas spp. was identified (fig. 1.). The results demonstrate that after 100 days of cultivation, the microorganisms in the consortia retain their viability, the titer being from 7.00 Ч 106 CFU/mL to 26.00 Ч 106 UFC/mL.
