A primary concern with composting is the lack of knowledge about the fate of widely used pesticides. Also, there is increasing interest in the use of composting as a bioremediation method for soils contaminated with xenobiotics such as TNT, PCBs, chlorophenols and PAHs. We used a laboratory scale composting system to determine the extent of mineralization, incorporation into humic matter, and v...

BACKGROUND Animal manure is a reservoir of antibiotic resistance genes (ARGs) that pose a potential health risk globally, especially for resistance to the antibiotics commonly used in livestock production (such as tetracycline, sulfonamide, and fluoroquinolone). Currently, the effects of biological treatment (composting) on the transcriptional response of manure ARGs and their microbial hosts a...

Abstract Background Livestock manure is an important reservoir of antibiotic-resistant bacteria (ARB) and antibiotic-resistance genes (ARGs). The bacterial community structure diversity are usually studied using high-throughput sequencing that cannot provide direct evidence for ARB changes. Thus, little known about the distribution ARB, especially in presence different antibiotics composting pr...

Actinomycetes are known to produce an extensive range of bioactive compounds as well as variety of enzymes having multiple biotechnological applications. They are an important source of lignocellulose hydrolyzing enzymes and constitute considerable proportion of the soil or aquatic micro-flora responsible for degradation of biomass in natural environment. Presently, most of the commercially exp...

Raw mushroom waste has been an enormous solid waste, not only causing a huge cut on profit margin of industries but also leading to environmental pollution. Unfortunately, the current utilization methods, such as pharmaceutical extractions, are unable keep up with generation rate due large-scale production. Yet, raw produce biomass pellets for energetic purposes and role electric composter shor...

Composting is an alternative method of carcass disposal in those situations when conventional methods are inadequate. With proper maintenance and monitoring, carcass composting systems can be safe and efficient with minimal environmental impacts. Importantly, proper composting eliminates many pathogens and may reduce levels of carcass contamination with spore-forming bacteria, prions, and other...

UNLABELLED Ammonia emissions were quantified for the laboratory-scale composting of three typical organic wastes with medium nitrogen content: organic fraction of municipal solid wastes, raw sludge and anaerobically digested sludge; and the composting of two wastes with high nitrogen content: animal by-products from slaughterhouses and partially hydrolysed hair from the leather industry. All th...
