LARGE-SCALE MICROBIAL DEGRADATION OF REFRACTORY ORGANIC COMPOUNDS Ralph R. Wilkinson and Fred C. Hopkins Midwest Research Institute, Kansas City, Missouri , USA George D. Ward Br Associates Inc., Portland, Oregon , USA Abstract - Landfarming is a technique which utilizes microorganisms in soils to biodegrade municipal and Cited by: 1.   A number of toxic synthetic organic compounds can contaminate environmental soil through either local (e.g., industrial) or diffuse (e.g., agricultural) contamination. Increased levels of these toxic organic compounds in the environment have been associated with human health risks including by: Decomposition of organic matter is the most essential microbial process occurring in soil. From: Reference Module in Earth Systems and Environmental Sciences, Decomposition of organic matter involves four component processes: photo-oxidation, leaching, comminution, and mineralization. Arthropods are key factors influencing comminution and.   The course of the CO 2 evolution rates of soil samples has been followed continuously in the absence and in the presence of various organic compounds. After an incubation period of hours at 13 and 20°C the CO 2 evolution from pasture soil (containing % soil organic carbon) amounted to and μg CO 2 −C.g soil −1.h −1, Cited by:

Volatile organic compound analysis may represent a new emerging field, soil volatilomics. In soils, VOCs are mainly produced by plants (Stotzky and Schenck ; Kesselmeier and Staudt ) and microorganisms (Stahl and Parkin ; Leff and Fierer ). Volatile organic compounds emitted by plant rootsCited by: Humid tropical forests have the fastest rates of organic matter decomposition globally, which often coincide with fluctuating oxygen (O 2) availability in surface ial iron (Fe) reduction generates reduced iron [Fe(II)] under anaerobic conditions, which oxidizes to Fe(III) under subsequent aerobic conditions. A number of toxic synthetic organic compounds can contaminate environmental soil through either local (e.g., industrial) or diffuse (e.g., agricultural) contamination.

The decomposition of organic matter in soils Fred G. Merkle University of Massachusetts Amherst Follow this and additional works at: This thesis is brought to you for free and open access by [email protected] Amherst. It has been accepted for inclusion in Masters Theses -Cited by: TP Hydrogen peroxide has been used to destroy a variety of organic contaminants in soil including creosote2, coal d, pentachlorophenol (PCP)'$4*5*6, TCE4p7*', trifluralin', hexadme', dieldrin', and PCE9. Several of these authors treated contaminated soils with H alone7** while others supplemented their treatment systems with iron4*6i9 or combined chemical oxidation Cited by: 9. Decomposition of Organic chlorine Compounds by Fluorescent Pseudomonas and Bacillus Fluorescent Pseudomonas and Bacillus that separated from the sample model were cultivated at 37 degrees C. on YG medium for 24 hours. Then, it is decomposed into farmate, glyoxylic acid, and dichloroacetic acid, and, finally is decomposed into carbon dioxide. Toxic Elements in Soils Firman E. Bear We got the word ^'toxin^' from the Greek word for huntsman's bow. ^Toxic" came to refer to the effects of the poisons that man appHed to the tips of arrows he used for hunting. A toxic element is one that brings in- jury and sometimes death to the living organism that absorbs it.
