ABSTRACT Synthetic microfibers are emerging environmental microplastic pollutants released from different industrial and domestic sources. The present investigation describes the isolation of potential bacterial strains microplastic‐contaminated sites Bhubaneswar city Odisha, India. Four morphologically distinct were isolated using 2% polyethylene glycol (PEG) supplemented nutrient agar (NA) medium screened for their polymer tolerance ability by growing them on 2%–8% PEG. A single microorganism capable 8% PEG was selected biodegradation experiment. Through 16S rRNA sequencing, strain identified as Exiguobacterium sp. with gene bank accession number ON318396. microbial strain's microfiber assessed in a laboratory setting over period 28 ± 2 days, utilizing optimized conditions an initial pH 7, mL inoculum volume, incubation temperature 30°C 2°C, 150 rpm, g polyester microfiber. In optimum conditions, weight loss treated sample 19.2%. degradation confirmed through scanning electron microscopic images viewing surfaces. Variation functional groups Fourier transform infrared spectrophotometry. Detection carbonyl (C═O) group stretching band at 1711 cm −1 ATR‐FTIR analysis biodegradation. isolate can efficiently degrade and, future, be employed promising solution sustainable treatment synthetic pollution.

Ecotoxicological Impact of Bioplastics Biodegradation: A Comprehensive Review

Processes, Год журнала: 2023, Номер 11(12), С. 3445 - 3445

Опубликована: Дек. 17, 2023

The emergence of bioplastics presents a promising solution to the environmental impact plastics industry. Bioplastics are engineered degrade in aquatic or soil environments. However, not all completely biodegradable, and some, like petrochemical-based plastics, may contribute plastic pollution. biodegradability is significantly different conditions such as soil, marine, composting At same time, produced from natural resources contain mixture known unknown materials show 32% cytotoxicity, 42% oxidative stress, 67% baseline toxicity, 23% antiandrogenicity bioassays. extensive biodegradation can also change nutrients, leading eutrophication stunted plant growth. many concerns have arisen, according which be an alternative option for global pollution long run, limited studies focus on this scenario. This review aims provide comprehensive overview by microorganisms their ecotoxicological impacts marine health. In conclusion, while potential sustainable conventional it essential address regarding complete toxicity. Therefore, methods must used production ensure positive environment.

Evaluation of azo dyes degradation potential of fungal strains and their role in wastewater treatment

Saudi Journal of Biological Sciences, Год журнала: 2023, Номер 30(8), С. 103734 - 103734

In the present investigation, two fungal strains were exploited to evaluate their degradation capability on Synozol Red, Yellow, and Navy-Blue dyes which gave utmost decolorization such as 40%, 70%, 90% by Aspergillus niger, 36%, 73%, 87% Trichoderma viride, respectively for 60 days. The Gas Chromatography-Mass Spectrometry (GC-MS) analysis of decolorized suggested that various compounds Caprolactam, Furazan-3-carboxamide, oxime, 4-amino-N, N-dimethyl, 6H-Pyrazolo[1,2-a] [1,2,4,5]tetrazine, Hexahydro-2,3-dimethyl, Benzene, 1-propenyl, Dihydroxymaleic acid, Arsenous tris(trimethylsilyl) ester produced fungi helped in removal from wastewater. laccase activity degraded was proof both positively enzyme biodegradation carcinogenic into less harmful products. A. niger extracted relative 262%, 265%, 145.7% Navy Blue, respectively. Similarly, laccase, obtained T. showed 187.5% against 215% 202% Blue. Furthermore, supernatant fungi-decolorized wastewater used check phytotoxicity Vigna radiata, excellent results. Both strains, basis dye potential, can be ameliorate contaminated with azo dyes.
