Microbial approach to improving aerobic stability of silage

Nigerian Journal of Animal Science, 2022
Aerobic deterioration of silage is a major challenge in the feed value chain. This review discusses microbial mitigations to improving aerobic stability of silages. Early detection of silage deterioration at the face of the silo is important to reduce further ingress of spoilage organisms into deeper layers of the silage.

Stabilization of mechanically biologically treated waste in anaerobic, aerobic and semi-aerobic bioreactors

Waste Management & Research: The Journal for a Sustainable Circular Economy, 2021
The study aims to investigate the application of anaerobic (AN), aerobic (AER) and semi-aerobic (SA) laboratory scale landfill bioreactors for stabilization of mechanically and biologically treated (MBT) waste of Bangalore city. All major parameters pertaining to the waste, leachate and biogas are continuously monitored during the experiment. Carbon (C)

Decolourization of azo, anthraquinone and triphenylmethane dyes using aerobic granules: Acclimatization and long-term stability

Chemosphere, 2021
The long-term stability of aerobic granules is critical for decolourization of different dyes in textile wastewater. Here, we investigated dye decolourization and the stability of acetate-cultivated granules after exposure to dyes.

Effect of Rotifers on the Stability of Aerobic Granules

Environmental Technology, 2007
The current study evaluated the effect of rotifers on the stability of aerobic granules. Two sequence batch reactors (SBRs) with airflow rates of 4 (R1) and 6 (R2) 1 min(-1), respectively, were used to develop aerobic granules. Granules were well developed with excellent settleability in terms of SVI30 (sludge volume index,) of about 50 ml g(-1) in ...

Kinetics of aerobic sludge stabilization

Water Research, 1972
Abstract The aerobic decomposition of organic sludge solids, measured in volatile solids and bacterial mass (respiration rate, acetate decomposition activity) has been determined at different temperatures ( Tables 1 and 2). Based on the rates of respiration (which is directly proportional to the reaction constant of decomposition) the ...

Methods for measuring the degree of stability of aerobic stabilized sludges

Water Research, 1977
Abstract This study was conducted to find one or several parameters that can be used as a measure of the degree of stability of wastewater sludges and to define in terms of the measured parameters what is meant by a fully stabilized sludge. Based on the data from this study, the following requirements regarding odour should be met before an ...

Studies on the aerobic stability of commercial silages

Journal of the Science of Food and Agriculture, 1979
AbstractEighteen commercial silages from ten different farms located in south‐east Scotland were exposed to air in polystyrene containers over a 9‐day period. The silages were subjected to detailed biochemical and microbiological analyses prior to aeration.

Aerobic and Anaerobic Landfill Stabilization Process

Journal of the Sanitary Engineering Division, 1970
A series of laboratory investigations was performed to replicate the aerobic and anaerobic sanitary landfill environment. The oxygen demand of solid waste was found to be directly proportional to the amount of easily utilizable organics present in the test material.

Respirometric assessment of aerobic sludge stabilization

Bioresource Technology, 2010
Aerobic sludge stabilization was assessed respirometrically with the sludge taken from the secondary settling tank of a domestic wastewater treatment facility in Istanbul, Turkey. Zero-order removal rates of 178, 127 and 44 mg/L day were found for Suspended Solids (SS), Volatile Suspended Solids (VSS) and Total Organic Carbon (TOC) at the end of 18 ...

Localization and stability of hydrogenases from aerobic hydrogen bacteria

Archives of Microbiology, 1977
Alcaligenes eutrophus strains H 16, B 19, G 27 and N9A contained two different hydrogenases. One enzyme catalyzed the reduction of NAD by hydrogen and was strictly localized in the soluble cell fraction. While the second enzyme was found to be particulate and unable to react with NAD.
