Co-digestion, pretreatment and digester design for enhanced methanogenesis
Renewable and Sustainable Energy Reviews, 2015Abstract Co-digestion, pretreatment and digester design are the key techniques for enhanced biogas optimization. Co-digestion dilutes the inhibitory effects of substrates, balance the micro and macronutrients, increase the organic loading with consequent higher methane yields per unit of digester volume; lastly diversify and synergize the microbial ...

Deacetylation and enhancement of digestibility
Agriculture and Environment, 1981Abstract The nylon bag technique has been used to study the effects of various reagents on the digestion of grass cell walls and straws in the sheep rumen. A large proportion of the acetyl groups were removed by sodium alkoxides in alcoholic solution with appreciable improvement in digestibility.

Performance enhancement of batch aerobic digesters via addition of digested sludge
Journal of Hazardous Materials, 2000The impact of the feed sludge (FS) concentration and addition of digested sludge (DS) to an aerobic digester was evaluated with respect to its capability for removal of the total suspended solids (TSS) and volatile suspended solids (VSS). The aerobic digesters, which operated in a batch mode at constant temperature and mixing rate, were initially ...

Contrast-enhanced endoscopic ultrasonography in digestive diseases
Journal of Gastroenterology, 2012Contrast-enhanced endoscopic ultrasonography (CE-EUS) was introduced in the early 1990s. The concept of the injection of carbon dioxide microbubbles into the hepatic artery as a contrast material (enhanced ultrasonography) led to "endoscopic ultrasonographic angiography". After the arrival of the first-generation contrast agent, high-frequency (12 MHz)

Functional foods with digestion-enhancing properties
International Journal of Food Sciences and Nutrition, 2011On analyzing the traditional societies' plant lore by treatment and plant categories, one cannot but notice the greater weight given to treatment of digestive disturbances and ailments compared to modern Western pharmacopoeias, and the blurred boundaries between medicines and foods, in contrast to the clear-cut distinction made in contemporary ...

The effects of digestive enhancer supplements on digestibility in leisure horses
Proceedings of the British Society of Animal Science, 2009Certain commercial horse feed supplements based on active yeast and its derivatives, and have been shown to improve digestion of feed (Medina et al, 2002), although this data is very limited and is mostly derived from studies in other species, such as pigs or cattle.

Illumination enhances methane production from thermophilic anaerobic digestion
Applied Microbiology and Biotechnology, 2006Incandescent lamp illumination enhanced methane production from a thermophilic anaerobic digestion reactor (55 degrees C) supplied with glucose. After 10 days of operation, the volume of methane produced from light reactors was approximately 2.5 times higher than that from dark reactors.

Pretreatments to enhance the digestibility of lignocellulosic biomass
Bioresource Technology, 2009Lignocellulosic biomass represents a rather unused source for biogas and ethanol production. Many factors, like lignin content, crystallinity of cellulose, and particle size, limit the digestibility of the hemicellulose and cellulose present in the lignocellulosic biomass. Pretreatments have as a goal to improve the digestibility of the lignocellulosic
