Comparative Analysis for Bioremediation of Plastic and Dye Degradation

Abstract

The leading environmental risk factor for disease and premature death is pollution, with plastic and dye pollutants being the most common in developing countries. The global textile industry contributes to pollution by releasing contaminated wastewater into water bodies, leading to a decline in water quality. Plastic pollution is a widespread issue affecting various environments, emphasizing the urgent need for a global response to combat the adverse effects of pollution on human health and the environment. Anoxybacillus sp. PDR2 is a soil bacterium possessing natural competence. By nature, it is a thermophile, capable of biodegrading industrial dyes. Pseudomonas sp. B10, Gram-negative bacteria, is a strain capable of degrading Polyethylene Terephthalate (PET) plastic. To detect the genome-level mutations, comparative genomic analysis was performed using a free and open source software, Galaxy. Using five different variant callers (Samtools, Varscan, Freebayes, Sniffles, Ivar), mutations were detected at various loci resulting in the modifications of the genes. The primary goal of this investigation was to perform a comparative analysis of the whole genome sequencing of two bacterial species, along with their reference strains. The purpose was to identify potential solutions for the degradation of plastics and industrial dyes. By examining the genetic composition of these bacteria, this analysis had provided valuable insights into the genetic makeup of these bacteria and their ability to break down PETs and dyes.
