Summary

Researchers systematically reviewed microbial approaches to degrading low-density polyethylene (LDPE), finding that bacterial genera like Enterobacter, Pseudomonas, and Bacillus, along with certain fungi and microbial consortia, are most effective, with scanning electron microscopy, gravimetry, and FTIR identified as the most reliable techniques for measuring biodegradation.

Study Type Review

The most efficient microorganisms in LDPE degradation are Enterobacter spp., Pantoea spp., Pseudomonas spp., Escherichia coli, and Bacillus spp.; in fungi Neopestalotiopsis phangngaensis, Colletotrichum fructicola, and Thyrostroma jaczewskii; and in microbial consortia, those formed by Enterobacter spp. and Pantoea sp., and that of P. protegens, Stenotrophomonas sp., B. vallismortis and Paenibacillus sp.; and the most effective techniques used in LDPE biodegradation are SEM, gravimetry, and FTIR.
