Plastic waste has become a significant global ecological concern due to its substantial harmful impacts. They are eventually colonized and transformed by diverse microbial communities known as the ‘‘plastisphere”. Only a limited group of microbes have been identified so far due to the prevalence of non-culturable strains that inhabit polymer substrates. We investigated the community diversity and predictive functionality of the plastisphere microbiota using a high-throughput next-generation sequencing (NGS) approach to unveil their plastic degrading potential. Samples were collected from four different plastic-enriched disposal sites adjacent to Kolkata, West Bengal, India, followed by processing, gDNA extraction, library preparation, and sequencing. The most prevalent phyla were Proteobacteria, followed by Bacteroidetes, Actinobacteria, Cyanobacteria, Firmicutes, and Verrucomicrobia. The functional profiling revealed that genes associated with metabolism, cellular processes, and signalling were most prevalent, followed by poorly characterized information storage and processing. In this study, we predicted the existence of a beneficial microbiome associated with bioremediation and plastic degradation, which suggests the potential utilization of plastics as primary carbon sources. Our findings also highlighted the existence of promising microbial enzymes associated with the biodegradation of several plastic substrates.Furthermore, our research unveiled the enriched distribution of beneficial microbiome in the studied metagenome, which offers a diverse prospect. This investigation establishes a connection between the structure of microbial communities and diverse genes actively engaged in the biodegradation of plastic waste within plastic disposal sites. These beneficial degraders can be investigated further for broad-spectrum applications in plastic bioremediation. Subsequent explorations of their plastic degrading enzymes will provide profound contributions to plastic pollution mitigation. |
