Environmental biodegradation of polyethylene

Polymer Degradation and Stability, 2003
The degradation of a commercial environmentally degradable polyethylene was investigated in two stages. Firstly by abiotic oxidation in an air oven to simulate the effect of the compost environment and secondly in the presence of selected microorganisms.

Environmental microbiology: biodegradation

Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1982
Abstract A genuinely new dimension to microbiology concerns the fate of synthetic compounds dispersed throughout the biosphere, with xenobiotic compounds representing a major challenge to the metabolic versatility of microorganisms. While microbial bio-degradation of many of these compounds proceeds by the activity of single species ...

Environmental risk, toxicity, and biodegradation of polyethylene: a review

Environmental Science and Pollution Research, 2022
Polyethylene is the second-most-commonly-used commercial polymer. It is used in various industries, including agricultural mulches, composite materials, and packaging. Since polyethylene is not biodegradable, it can persist for a long time in water and soil, strangling otherwise fruitful land.

Biodegradation of Chemicals of Environmental Concern

Science, 1981
Microorganisms in soils and waters convert many synthetic organic chemicals to inorganic products. Other compounds are transformed only by cometabolism. These microbial processes may lead to environmental detoxication, the formation of new toxicants, or the biosynthesis of persistent products.

Fabrication of Environmentally Biodegradable Lignin Nanoparticles

ChemPhysChem, 2012
AbstractWe developed a method for the fabrication of novel biodegradable nanoparticles (NPs) from lignin which are apparently non‐toxic for microalgae and yeast. We compare two alternative methods for the synthesis of lignin NPs which result in particles of very different stability upon change of pH.

Biodegradable polymers and environmental interaction

Polymer Engineering & Science, 1998
AbstractBiodegradable polymers are by definition those that degrade as a result of the action of microorganisms and/or enzymes. The rate of this biodegradation may vary from hours to years depending on the molecular architecture of the polymer in question.

Biodegradation of chemicals in a standardized test and in environmental conditions

Chemosphere, 2003
The estimation of biodegradation rates is an important source of uncertainty in chemical risk assessment. The existing OECD tests for ready biodegradability have been developed to devise screening methods to determine whether a chemical is potentially easily biodegradable, rather than to predict the actual rate, of biodegradation in the environment ...

Classification, Source, and Effect of Environmental Pollutants and Their Biodegradation

Journal of Environmental Pathology, Toxicology and Oncology, 2017
Any foreign chemical substance that is unusually present within an organism or is unexpectedly found in the environment at a higher concentration than the permissible limits can be termed a xenobiotic or a pollutant. Such substances include carcinogens, drugs, food additives, hydrocarbons, dioxins, polychlorinated biphenyls, pesticides or even some ...

Phenylmercuric acetate biodegradation by environmental strains of pseudomonas species

Research in Microbiology, 1989
Organomercurial pollution occurring in the Rhine river in 1986 led us to study the possibility of depollution by mercury-resistant environmental aquatic strains. Four species of Pseudomonas were investigated for their ability to biotransform phenylmercuric acetate (PMA). Such biological depollution was demonstrated to be due to an enzymatic activity in

Biodegradability of polymers in environmental

2016
With increasing global consumption and their natural resistance to degradation, plastic materials and their accumulation in the environment is of increasing concern. Approximately 140 million tonnes of synthetic polymers are produced worldwide each year.
