A Comparative Study of Low-density Polyethylene Shopping Carry Bag Degrading Bacteria Isolated from Marine and Garden Soil
AI summary Read the abstract
Researchers isolated bacteria from marine and garden soil and tested their ability to degrade low-density polyethylene (LDPE) plastic bags. Two species — Paenibacillus castanea and Riemerella anatipestifer — achieved up to 7.3% weight loss of LDPE after 35 days, demonstrating that soil bacteria can slowly break down this common plastic. This research is relevant to understanding natural LDPE degradation pathways and the formation of microplastics as larger plastic items fragment in soil and marine environments.
An attempt was made to investigate the extent of biodegradability of LDPE by six strains were isolated from marine and garden soil. The phenotypic fingerprint, similar to the Gen III biolog, was utilised to activate the substrate utilisation of strains, which were identified as Paenibacillus castanea and Riemerella anatipestifer. The optimal conditions for both was found to be pH of 7.1, temperature of 37oC, contact time of 72hrs, LDPE weight & inoculums volume of Paenibacillus castanea; 0.030 g & 3 % (v/v) for Riemerella anatipestifer; 0.042 g & 4% (v/v). LDPE degradation was confirmed by the weight loss which was found to be 7.30 % for Paenibacillus castanea & 5.40 % for Riemerella anatipestifer after an incubation of 35 days. The present study suggest that Paenibacillus castanea is efficient, cost effective, eco friendly and safe approach for the elimination of LDPE compared to Riemerella anatipestifer from the environment. The changes in the functional group of Paenibacillus castanea was further detected by FTIR. These results indicate that Paenibacillus castanea can prove to be a suitable candidate for LDPE treatment without causing any harm to our health or environment.

A Study on Comparison of Efficiency of Low-Density Polythene (LDPE) Degradation Under Aerobic and Anaerobic Conditions by Microorganisms Isolated from Soil
AI summary Read the abstract
Researchers compared how well soil-isolated microorganisms degrade low-density polyethylene under aerobic versus anaerobic conditions, finding that aerobic bacteria achieved greater plastic mass loss over the study period. The findings suggest aerobic microbial degradation is more effective for LDPE breakdown, informing the design of bioremediation strategies for plastic-contaminated soils.
Degradation of LDPE Using the Winogradsky Column Containing OtteriDumpsite Soil: Prediction of Mechanism and Metabolites Determination
AI summary Read the abstract
Researchers used a soil microbial community system (Winogradsky column) to degrade low-density polyethylene (LDPE) plastic, the material used in grocery bags. The bacterial community broke down the plastic and produced identifiable metabolites, suggesting that soil microbes can slowly but measurably attack LDPE. This matters for understanding how plastic waste might naturally degrade in landfills and why microplastics form and persist in the environment.
Biodegradation of LDPE plastic by local strain of Bacillus sp. isolated from dump soil of Pekanbaru, Indonesia
AI summary Read the abstract
Scientists isolated a local strain of Bacillus bacteria from landfill soil in Indonesia and tested its ability to break down low-density polyethylene (LDPE) plastic. The bacteria showed measurable ability to degrade LDPE, reducing plastic weight over time. This research supports the potential for using locally sourced soil bacteria in plastic biodegradation efforts.

AI summary Read the abstract
Researchers tested five bacterial strains for their ability to biodegrade low-density polyethylene microplastics over four months. Pseudomonas aeruginosa showed the most significant degradation with an 18.2% weight loss, followed by Bacillus subtilis at 16.1%. The study demonstrates that naturally occurring soil bacteria can break down polyethylene microplastics, suggesting a potential biological approach to addressing plastic waste pollution.
Biodegradation of Low Density Polyethylene (LDPE) using marine bacteria isolated from tropical beaches of megacity Mumbai
AI summary Read the abstract
Marine bacteria isolated from plastic debris buried in beach sediments at seven Mumbai beaches were able to colonize and partially degrade low-density polyethylene (LDPE) plastic. Identifying bacteria naturally adapted to plastic-rich marine environments is a step toward developing biological tools for plastic degradation, though the process is currently far too slow to address the scale of ocean plastic pollution without significant enhancement.
