Biodegradation 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...
متن کاملBiodegradation of carbaryl and phthalate isomers by soil microorganisms
Pseudomonas sp. strain PP4 and C5 utilize phthalate isomers (o-, mand p-) and carbaryl as carbon source, respectively. Degradative pathways were elucidated by isolating and characterizing metabolites, whole-cell O2 uptake and enzyme activity studies. Metabolic studies suggest that phthalate isomer degrading pathways converge at 3,4-dihydroxybenzoic acid. Phthalate dioxygenases responsible for t...
متن کاملethylene oligomer biodegradation by microorganisms isolated from landfill soils
such petroleum hydrocarbons as ethylene oligomer are among soil and water pollutants. physical and chemical methods employed in elimination of these pollutants, in addition to being inefficient, are damaging to the environment too. throughout the present research, powerful decomposer isolates, namely: lysinibacillus xylanilyticus (a bacterium isolate), and aspergillus niger (a fungal isolate) w...

ویژگی های زمین شیمیایی، کانی شناسی، و میکرومورفولوژیکی خاک ها و سنگ مادر مربوطه در منطقه بین بخش های جنوبی زاگرس و خلیج فارس تا دریای عمان(استان هرمزگان، ایران) مورد بررسی قرار گرفت. هدف های این مطالعه شناسایی تغییرات در خصوصیات فیزیکی، شیمیایی، و ترکیب کانی شناسی خاک، مطالعه میکرومورفولوژی و تکامل خاک، و بررسی توزیع عنصر خاک بر اساس هوازدگی، پروسه های خاک و زمین شناسی جهت توصیف اثرات مواد مادر...
15 صفحه اولEfficiency of indigenous and inoculated cold-adapted soil microorganisms for biodegradation of diesel oil in alpine soils.
Biodegradation of diesel oil (5 g(middot)kg [soil dry weight](sup-1)) was investigated in five alpine subsoils, differing in soil type and bedrock, in laboratory experiments during 20 days at 10(deg)C. The biodegradation activities of the indigenous soil microorganisms and of a psychrotrophic diesel oil-degrading inoculum and the effect of biostimulation by inorganic fertilization (C/N/P ratio ...
