“…Because it possessed the decolorization and degradation qualities required for the biotransformation of the MO dye, this strain was selected for the degradation experiments. A study done by Pathak and Kumar [ 29 ] also isolated four bacteria, Bacillus sp., Paracoccus sp., Pseudomonas sp., and Acinetobacter sp., from waste disposal sites showed positive results of polymer-degrading microorganisms [ 62 ]. studied the degradation of malachite green dye by a single isolated bacterium, Pseudomonas sp.…”

“…Tests for catalase, oxidase, protease, and indole synthesis were part of the biochemical analysis [ 28 ]. The biochemical analysis was done using biochemical HiCarboTM testing kits (KB009 and KB003) and culture characterized according to Bergey's manual [ 29 ]. A qualitative laccase activity test was performed on bacterial stain ED1 by inoculating bacteria on a CDA plate enriched with 3 mM ABTS dye at 27 °C for 48 h. The appearance of the green colored zone around the bacterial colony indicates the presence of laccase activity in bacteria [ 30 ].…”

Plastics are synthetic polymers, which are frequently used in daily life for a wide range of purposes. These plastic wastes are accumulated and generate plastic pollution in the environment. It needs many years for complete deterioration in the environmental conditions. Biodegradation is the most promising method to treat plastic pollution, as the microorganisms utilize the low-density polyethylene (LDPE) as a sole source of carbon, and this indicates an innovative approach to manage the problem of plastic waste. The isolate SARR1 was identified as Bacillus licheniformis using the National Center for Biotechnology Information (NCBI) database. The isolate SARR1 showed an LDPE removal rate (K) of 0.069 g day −1 with a half-life of approximately 335.32 days to degrade LDPE strips. The biomass production was 0.98 ± 0.006 gl −1 (X m ) during the incubation of 30 days, and the percentage of crystallinity was significantly decreased from 71.69% to 50.78% due to biodegradation. The esterase and lipase activity of isolate SARR1 was studied using UV visible spectroscopy. The gas chromatography-mass spectrometry analysis confirmed the synthesis of acetone, diazene dimethyl, and carbamimidothioic acid, 1-methylethyl ester with different peak area percentages of 23.38%, 65.58%, and 11.04%, respectively. Seed germination study showed that the compounds formed after biodegradation of LDPE by bacterial strain SARR1 were eco-friendly.

“…Engineered nanomaterials are becoming more The potential of nanomaterials to improve the effectiveness of currently employed microplastic removal methods and provide creative answers to problems that arise. 33 Conventional biological methods, such as the enzymatic process of plastic degradation, are inefficient because of environmental limits. Frequent landfilling and burning of plastic waste diminish the soil's ability to absorb water, leading to soil sterility.…”

Plastics pose a huge threat to the environment. Plastic accumulation in the land and the seas is now the world’s most terrorising problem, mainly because of its non-degrading character. Plastic degradation has always been a next to impossible concept in the field of science, but nanotechnology provides a revolutionary and modern way to solve the problem of plastic accumulation in the environment. One of the great advantages of nanoparticles is that we can increase and decrease the rate of biodegradation depending on our needs. Nanoparticles enhance the polythene degradation capacity of the microorganisms by altering their metabolic cycles. Numerous studies showed conclusively that the incorporation of nanotechnology enhances the ability of microorganisms to degrade polythene materials. Even though bio degradable plastics are nowadays produced in large quantities to substitute polythene materials, they fail to match the brittleness of plastics. Biodegradable plastics have poor thermal, mechanical and low gas barrier qualities, which are their main drawbacks. To overcome this, nanoparticles are incorporated into the biopolymers. If an appropriate balance between nanotechnology, microbiology and biotechnology is found, plastic degradation can be done economically and feasibly in all the areas.
