Biotreatment of Sludge and Reuse
Sewage sludge, a by-product of domestic wastewater treatment plant, also known as “biosolids”, is generated in millions of tons each year. While...

Modeling the biodegradation of multicomponent organic matter in an aquatic environment: 3. Analysis of lignin degradation mechanisms
Mechanisms of enzymatic degradation of a persistent organic substance are discussed in the case of lignin. The major groups of lignin-decomposing...
-
Microbial Ecology
Ecology is the science that specifically examines the relationship between microorganisms and their biotic and abiotic environment. Like plant,...
-
Nitrogen deposition effects on soil organic matter chemistry are linked to variation in enzymes, ecosystems and size fractions
Recent research has dramatically advanced our understanding of soil organic matter chemistry and the role of N in some organic matter...
-
The number of microorganisms and the microbiological activity of human-modified cryogenic pale soils of Yakutia
Specific features of the microbial population—the high number of all the groups of microorganisms (1.6 × 10 3 –3.5 × 10 7 ) similar to their abundance in...

The Impact of Urbanization on Soils
Cities are important driving forces in environmental trends as a consequence of the increase in the share of the global population that reside in...

The potential bioavailability of organic C, N, and P through enzyme hydrolysis in soils of the Mojave Desert
Increases in the growth rate of plants and microbes in the Mojave Desert in response to predicted increases in precipitation and CO 2 due to global...
-
Ecology-related Microbiological and Biochemical Parameters in Assessing Soils Exposed to Anthropogenic Pollution
Soil is the foundation of the entire biosphere, and the most important complex interface for the global transformation and interchange of matter and...
-
Effect of oil and oil products on lipase activity in gray forest soil
The effect of different rates of oil and oil products on the lipase activity in gray forest soil was studied under field and laboratory conditions....
-
Enzyme activity responses to nutrient loading in subtropical wetlands
Eutrophication caused by anthropogenic nutrient inputs is one of the greatest threats to the integrity of freshwater wetlands. The resultant changes...

Stimulation of nitrogen fixation in soddy-podzolic soils with fungi
Stimulation of nitrogen fixation in soddy-podzolic soils is related to the hydrolytic activity of fungi decomposing plant polymers. It was found that...

Detrital Controls on Soil Solution N and Dissolved Organic Matter in Soils: A Field Experiment
We established a long-term field study in an old growth coniferous forest at the H.J. Andrews Experimental Forest, OR, USA, to address how detrital...

Extracellular Enzyme Activities and Soil Organic Matter Dynamics for Northern Hardwood Forests receiving Simulated Nitrogen Deposition
Anthropogenic nitrogen enrichment alters decomposition processes that control the flux of carbon (C) and nitrogen (N) from soil organic matter (SOM)...
-
Long-term effects of elevated nitrogen on forest soil organic matter stability
Nitrogen addition may alter the decomposition rate for different organic-matter pools in contrasting ways. Using a paired-plot design, we sought to...
-
Impacts of chronic nitrogen additions vary seasonally and by microbial functional group in tundra soils
Previous studies have shown that fertilization with nitrogen depresses overall microbial biomass and activity in soil. In the present study we...

Screening of Fungal Strains for Remediation of Water and Soil Contaminated with Synthetic Dyes
Using Remazol Brilliant Blue R (RBBR), strains of terrestrial white rot (WRF) and marine fungi (MF) were screened for efficient decolorization. Dye...
-
Development of Immunomicroscopic Methods for Bioremediation
In nature, wood can be completely degraded by lignolytic fungi. Basidiomycetous white-rot fungi are particularly efficient wood degraders because of...
-
Allocation of extracellular enzymatic activity in relation to litter composition, N deposition, and mass loss
Decomposition of plant material is a complex process that requiresinteraction among a diversity of microorganisms whose presence and activity...

SOM management in the tropics: Why feeding the soil macrofauna?
This paper synthesises information on the food requirements of soil macroinvertebrates and some of their effects on soil organic matter dynamics....

Activity of ß-Glucosidase in the Presence of Copper or Zinc and Montmorillonite or Al-Montmorillonite
Various studies have shown that the activities of many enzymes in soil are inhibited by trace elements (Tyler, 1974; Haanstra and Doelman, 1991;...
