A combination of semipermeable membrane-covered composting systems and greenhouses was used to investigate the effects different insulation on aerobic fermentation mixed raw materials changes in characteristics feedstock. The greenhouse increased peak temperature by 6.53 °C, average 28.2%, extended duration effective high-temperature stage (temperature ≥ 50 °C) 14 days. decomposition percentage...

1. An organism has been isolated from peat soil which decomposes the specific capsular polysaccharide of Type III Pneumococcus. 2. The isolation has been made possible by the use of a synthetic mineral medium containing the specific polysaccharide as sole source of carbon. By repeated transfers in this medium the potential capacity of the organism to decompose the specific substance has been pr...

Decomposition of natural populations of Lake Mendota phytoplankton dominated by blue-green algae (cyanobacteria) was monitored by using oxygen uptake and disappearance of chlorophyll, algal volume (fluorescence microscopy), particulate protein, particulate organic carbon, and photosynthetic ability (CO(2) up-take). In some experiments, decomposition of C-labeled axenic cultures of Anabaena sp. ...

THE bacterial decomposition of formic acid is a subject which, in spite of its apparent simplicity, still presents unsolved problems; it was in the hope of elucidating some of these that the present study was undertaken. The earliest observation on the subject was made by Hoppe-Seyler [1875]. Later Pakes and Jollyman [1901] studied the anaerobic decomposition ow formates by bacteria in a state ...

A laboratory experiment was conducted to determine the effect of temperature (2, 12, 22 °C) on the rate of aerobic decomposition of skeletal muscle tissue (Ovis aries) in a sandy loam soil incubated for a period of 42 days. Measurements of decomposition processes included skeletal muscle tissue mass loss, carbon dioxide (CO2) evolution, microbial biomass, soil pH, skeletal muscle tissue carbon ...

The nitroxyl anion (NO-) is a highly reactive molecule that may be involved in pathophysiological actions associated with increased formation of reactive nitrogen oxide species. Angeli's salt (Na2N2O3; AS) is a NO- donor that has been shown to exert marked cytotoxicity. However, its decomposition intermediates have not been well characterized. In this study, the chemical reactivity of AS was ex...

Inexpensive strategies for efficient decontamination of hazardous chemicals are required. In this study, the effect visible light (λ > 400 nm) on decomposition 2-chloroethyl ethyl sulfide (2-CEES, a sulfur mustard (HD) simulant) Au/TiO2 photocatalyst under anaerobic and aerobic conditions has been investigated in situ by diffuse reflectance infrared Fourier –transformed spectroscopy (DRIFTS)...

Composting is the process of converting organic waste into a nutrient-rich soil amendment. It an eco-friendly and sustainable way to manage it can have number benefits for environment. help reduce greenhouse gas emissions, improve quality, conserve water. also amount that goes landfills, which protect human health The inputs composting include food scraps, yard waste, other materials. These mat...

We studied the mechanism of formation of oxygen radicals during ferrous ion-induced decomposition of linoleic acid hydroperoxide using the spin trapping and chemiluminescence methods. The formation of the superoxide anion (O2*-) was verified in the present study. The hydroxyl radical is also generated through Fenton type decomposition of hydrogen peroxide produced on disproportionation of O2*-....
