Pretreatment of sugar cane bagasse for enhanced ruminal digestion
Applied Biochemistry and Biotechnology, 1996Crop residues, such as sugar cane bagasse (SCB), have been largely used for cattle feeding. However, the close association that exists among the three major plant cell-wall components, cellulose, hemicellulose, and lignin, limits the efficiency by which ruminants can degrade these materials.

Enhancement of anaerobic digestion by adding elemental sulfur
Bioresource TechnologyIn this study, a new approach to enhance methane (CH4) production from organic substrates in anaerobic digestion (AD) has been discovered. That is, the addition of elemental sulfur (S0) particles into the AD system promotes the synergistic growth of elemental sulfur disproportionation bacteria, acidogenic bacteria and methanogenic archaea, thus ...

Perspective on enhancing the anaerobic digestion of waste activated sludge
Journal of Hazardous Materials, 2020Anaerobic digestion (AD) of waste activated sludge (WAS) is an important bio-energy strategy that has been hindered by low conversion efficiency. This paper presents a comprehensive review of research on the sludge's property and enhancing AD of WAS, and proposes two perspectives of material structure and microbial activity on improving AD efficiency ...

Enhanced anaerobic digestion of waste activated sludge digestion by the addition of zero valent iron
Water Research, 2014Anaerobic digestion is promising technology to recover energy from waste activated sludge. However, the sludge digestion is limited by its low efficiency of hydrolysis-acidification. Zero valent iron (ZVI) as a reducing material is expected to enhance anaerobic process including the hydrolysis-acidification process. Considering that, ZVI was added into

This paper describes an in vitro study that tests the proposition that actinidin from green kiwifruit influences the digestion of proteins in the small intestine. Different food proteins, from sources including soy, meat, milk, and cereals, were incubated in the presence or absence of green kiwifruit extract (containing actinidin) using a two-stage in ...

Enhanced Anaerobic Digestion by Inoculation With Compost
2017108The increased use of the activated sludge system to treat municipal and industrial wastewater has led to a considerable production of sludge, which is potentially harmful to both the environment and human beings. Anaerobic digestion (AD) of waste-activated sludge (WAS) is a widely accepted method for sludge stabilization and biogas production.

Bioresource Technology, 2014
Anaerobic co-digestion of shredded grass with sewage sludge was investigated under various temperature conditions. The conversion of grass to methane was difficult to achieve under mesophilic conditions, while its methane yield was 0.19 NL/g VS-grass under thermophilic conditions. The mixture ratio of grass to sludge affected the methane yield, and the

Actinidin Enhances Gastric Protein Digestion As Assessed Using an in Vitro Gastric Digestion Model
Journal of Agricultural and Food Chemistry, 2010Consumption of kiwifruit has long been claimed anecdotally to assist in gastric digestion. This has generally been assumed to be due to the presence of the proteolytic enzyme actinidin; however, there is little published evidence supporting this assumption.

Struvite formation for enhanced dewaterability of digested wastewater sludge
Environmental Technology, 2013One of the main advantages of controlled struvite formation in digested sludge is an improvement in dewaterability of the digested sludge, which eventually leads to lower volumes of dewatered sludge that need to be transported. The effects of the control parameters for struvite formation, magnesium concentration and pH, on digested sludge ...

Insights into the enhancement of the ASB benthal solids digestion rate
Water Research, 2008Aerated stabilization basins (ASB) accumulate benthal solids as they provide biotreatment to wastewaters. The accumulated solids must digest at a rate that matches the rate of settling of fresh solids in order to maintain the water column depth at the design value.
