Biodegradation of Soil Contaminants
Many industrial and other human activities resulted in a widespread contamination of soils with various contaminants. Most of these contaminants are toxic to humans and animals . They reach humans and animals through migration into the atmosphere, groundwater and crops I. The pollution became especially disturbing in the past few decades, when the awareness of thi s problem resulted in the enor...
متن کاملDiffusion Limitation for Atrazine Biodegradation in Soil
Effects of sub-millimeter scale heterogeneity in chemical and microbial distributions on atrazine degradation were examined using Pseudomonas sp. strain ADP introduced into soil at a population mimicking atrazine-adapted soils (~2000 cells/g), and employing a range of soil water pressures (−100, −300, −500 kPa). Heterogeneous cell distribution was employed in all treatments whereas uniformity o...
متن کاملBiodegradation of nonylphenol in soil.
We investigated the effects of various factors (brij 30, brij 35, yeast extract, hydrogen peroxide and compost) on the aerobic degradation of nonylphenol (NP) in soil and characterized the structure of the microbial community in that soil. Residues of NP were measured using gas chromatography-mass spectrometry (GC-MS) and a change of microbial communities was demonstrated using denaturing gradi...
متن کاملBiodegradation of Three Cellulosic Fabrics in Soil
The cellulosic fabrics cotton, rayon, and Tencel® are commonly used in the textile industry (Kroschwitz, 1990). The chemical composition of the fabrics is similar, but they differ in the arrangement of the cellulose polymers in the fabrics (Collier and Tortora, 2001). The basic polymer for all cellulosic fibers consists of repeating glucose units. For the cotton fabric, the cellulosic polymers ...
متن کاملBiodegradation of sorbed chemicals in soil.
Rates of biodegradation of sorbed chemicals are usually lower in soil than in aqueous systems, in part because sorption reduces the availability of the chemical to microorganisms. Biodegradation, sorption, and diffusion occur simultaneously and are tightly coupled. In soil, the rate of biodegradation is a function of a chemical's diffusion coefficient, sorption partition coefficient, the distan...
