Environmental aspects of PAH biodegradation

Applied Biochemistry and Biotechnology, 1995
Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous pollutants, some of which are on the US Environmental Protection Agency priority pollutant list. Consequently, timely clean-up of contaminated sites is important. The lower-mol-wt PAHs are amenable to bioremediation; however, higher-mol-wt PAHs seem to be recalcitrant to microbial degradation.

Biodegradation of toxic and environmental pollutants

Current Opinion in Biotechnology, 1991
Organic chemicals that are toxic to humans and to the environment can be transformed and metabolized by a variety of microorganisms. Such chemicals include trichloroethylene, chloroform, carbon tetrachloride, toluene, phenols, chlorinated phenols, polychlorinated biphenyls and polyaromatic hydrocarbons. This review focuses on some of the most important

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.
