Biodegradation of Chemicals of Environmental Concern
Science, 1981Microorganisms 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, 2012AbstractWe 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, 1998AbstractBiodegradable 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, 2003The 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, 2017Any 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, 1989Organomercurial 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
2016With 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.

Directions for environmentally biodegradable polymer research
Accounts of Chemical Research, 1993A major factor promoting interest in biodegradable polymers is the growing concern raised by the recalcitrance and unknown environmental fate of many of the currently used synthetic polymers. These polymers include both water-soluble and water-insoluble types.
