biological degradation

This biological degradation is a process known as bioremediation.

Co-metabolism is thus used as an approach to biological degradation of hazardous solvents.

Science tells a different story, a story of overfishing, pollution and biological degradation.

Under normal oxygen conditions, fungi, bacteria, and insects would have caused a biological degradation of the wood in short time.

The organism's ability to self-organize maximizes biological degradation of contaminants.

Microorganisms grow on the surface of the discs where biological degradation of the wastewater pollutants takes place.

MHT does not however include a stage of biological degradation (anaerobic digestion or composting).

The presence of mud and silt caused the ship to be preserved against corrosion and biological degradation.

Moreover, dampness initiates chemical and/or biological degradation of materials, which also causes pollution of the indoor air.

These titers decrease progressively with time by dilution as pigs grow as well as by biological degradation.

Plant litter and other biomass accumulates as organic matter in soils, and is degraded by chemical weathering and biological degradation.

Some materials such as some detergents may be capable of biological degradation and in such cases, a modified form of wastewater treatment can be used.

The biological processes in the term "bioslurping" refer to aerobic biological degradation of the hydrocarbons when air is introduced into the unsaturated zone.

Simple honesty would compel acknowledgement that no technology - not incineration, burial, recycling or accelerated biological degradation - is remotely adequate to handle our commercial waste.

Consequently, the larger, more complex chemical compounds may be slow to degrade or may even be recalcitrant to biological degradation (e.g., asphaltenes in No. 6 fuel oil).

Additionally, once the cells are disrupted, it is often essential to protect the desired product from biological degradation processes (e.g., proteases), from oxidation or other chemical events and from putrification.

"Biological degradation of the retinal environment is the heart of the problem," he said, "so even if you put in new cells with long telomeres, as far as I know the cells would die."
