Microbial biodegradation of polyaromatic hydrocarbons.
Polycyclic aromatic hydrocarbons (PAHs) are widespread in various ecosystems and are pollutants of great concern due to their potential toxicity, mutagenicity and carcinogenicity. Because of their hydrophobic nature, most PAHs bind to particulates in soil and sediments, rendering them less available for biological uptake. Microbial degradation represents the major mechanism responsible for the ...
متن کامل7. Microbial biodegradation of polyurethane
Polyurethane (PU) is a general term used for a class of polymers derived from the condensation of polyisocyanate and polyol. Polyurethanes are an important and versatile class of manmade polymers used in a wide variety of products in the medical, automotive and industrial fields. Depending on the chemical structures of the polyisocyanates and polyols, PU can adopt various forms ranging from fle...
متن کاملBiodeterioration vs Biodegradation: the Role of Microorganisms in the Removal of Pollutants Deposited on Historic Buildings
This paper describes some biodegradation processes originating from the activity of microorganisms in the black crusts of historic buildings. The crusts are mainly composed of gypsum, carbonaceous particles, and polycyclic aromatic hydrocarbons. The slowly dissolving gypsum from black crusts represents a continuous source of sulphur for microbial growth. The sulphate-bonding capacity of the she...

متن کاملMicrobial Culture Adaptation to Biodegradation of Dimethylterephthalate
45 microbial cultures have been isolated from a chemically polluted region, using dimethylterephthalate (DMT) as a sole carbon and energy source. They have been subjected to adaptive selection in order to increase their biodegradative potential. The gradual increase of the xenobiotic substrate concentration from 2.5 to 25 mM induced adaptive changes in the tested strains. 20% of the studied str...
