Use of coimmobilized biological systems to degrade toxic organic compounds.
The concept of coimmobilizing cell mass (and/or enzyme) and adsorbent in a hydrogel matrix for biodegradation of toxic organic chemicals was introduced. Under defined experimental conditions, the coimmobilized system using activated carbon and Phanerochaete chrysosporium was compared with nonimmobilized systems for the degradation of pentachlorophenol (PCP). It was demonstrated that the coimmob...
متن کاملEffect of adsorbents on degradation of toxic organic compounds by coimmobilized systems.
The use of coimmobilized systems for treatment of toxic organic compounds has been proposed. The proposed approach combines the use of adsorbents and laboratory identified microorganisms immobilized in a protective permeable barrier to achieve a greater degree of control over the remediation process. This study was launched to understand the effect of adsorbents and changes in adsorption on the...
متن کاملSource apportionment of exposure to toxic volatile organic compounds using positive matrix factorizationSource apportionment of exposure to toxic volatile organic compounds using positive matrix factorization
Data from the Total Exposure Assessment Methodology studies, conducted from 1980 to 1987 in New Jersey (NJ ) and California (CA) , and the 1990 California Indoor Exposure study were analyzed using positive matrix factorization, a receptor -oriented source apportionment model. Personal exposure and outdoor concentrations of 14 and 17 toxic volatile organic compounds (VOCs) were studied from the ...
متن کاملRapid screening for bacteria capable of degrading toxic organic compounds
Routine procedures for isolating and characterizing microorganisms capable of degrading toxic chemicals are time consuming and labor intensive. The objective of this paper is to describe a new method for screening aerobic bacterial isolates and consortia that will rapidly determine metabolic capacity for various toxic chemicals and access the use of various substrates as inducers in the degrada...
متن کاملPlant-Associated Bacterial Degradation of Toxic Organic Compounds in Soil
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 cancer. Plant-associated bacteria, such as endophytic bacteria (non-pathogenic bacteria that occur natura...
