Plastic-eating Bacteria as a Remedy for Plastic Pollution

-

 


Plastic pollution can have negative effects on human health as well as serious effects on marine ecosystems. The widespread production of polyethylene terephthalate (PET) single-use plastics poses a significant threat to aquatic and terrestrial ecosystems in terms of plastic waste. PET is a strong, clear and light plastic that is typically used for food and beverage packaging, as well as for other single-use applications. As a result, removing plastic from the environment is not only difficult but also ineffective financially. Numerous strains of bacteria are capable of biodegrading a variety of plastics. Utilizing beneficial micro-organisms that are capable of breaking down plastic could be an effective and long-term solution to all of the problems. Ideonella sakaeinsis 201-F6 is the most well-known heterotrophic bacteria that can use PET as its primary source of energy and carbon to degrade plastic in the environment. It has a place with the sort of Ideonella and the family Comamonadaceae. With the assistance of specific enzymes like PETase and MHETase, it can ultimately degrade plastic, potentially reducing the problem of plastic waste. Polyethylene terephthalate (PET) is first transformed by the PETase into mono-(2-hydroxyethyl) terephthalate (MHET), after which MHET is hydrolyzed to produce ethylene glycol (EG) and terephthalic acid (TPA). I. sakaiensis offers a novel strategy for recycling PET because it can mediate the direct transformation of non-biodegradable PET into plastic that is better for the environment.

A Study on Microbial Carriage on Door Handles Odo JI et al., 2024 As people come in contact with surfaces like keyboards, office furniture, toilet doors, buses and keke door handles, there is a probability of picking up microbes deposited on them. This study is aimed at evaluating the antibiogram and microbial carriage of campus buses and keke napep door handles. Thirty swab samples were obtained from buses and keke napep door handles. The samples were taken to the laboratory where they were serially diluted and inoculated. Identification, characterization and biochemical analysis were done using standard microbiological methods. Fungal colonies were macroscopically and microscopically examined for morphology and appearance. Bacterial isolated were identified to be Staphylococcus spp., Proteus spp., Escherichia coli and Shigella spp. Fungi isolated were identified to be Aspergillus niger, Mucor spp., Aspergillus fumigates, Rhizopus spp. and Yeast spp. This study has shown that for both...

Determination of Permethrin Samples using Leuco Crystal Violet Reagent

  Determination of Permethrin Samples using Leuco Crystal Violet Reagent A new sensitive spectrophotometric method for the determination of permethrin insecticide in environmental and agricultural samples has been developed. The reaction mechanism is based on complexation followed by coupling of permethrin with leuco crystal violet (LCV). This method is based on the measurement of red shift of absorbance band of LCV in the UV-Visible region of 200-800 nm. The resulting complex absorption spectra was observed at λmax = 580 nm. The color of permethrin was changed from colorless to violet by the addition of LCV. The effects of various pesticides and metal ions on the selective determination of permethrin were also studied. The analytical parameters were improved and effectively employed for permethrin assessment in a variety of environmental samples including water, soil and vegetables. The purpose of the present research was to design a method for the color complexation determination...
