Co-digestion, pretreatment and digester design for enhanced methanogenesis

Renewable and Sustainable Energy Reviews, 2015
Abstract 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 ...

Performance enhancement of batch aerobic digesters via addition of digested sludge

Journal of Hazardous Materials, 2000
The 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 ...

Enhanced on-plate digestion of proteins using a MALDI-digestion chamber

International Journal of Mass Spectrometry, 2017
Abstract A commercially available digestion chamber (SunDigest, SunChrom) is used for on-target digestion of proteins for subsequent direct MALDI-MS analysis. Temperature and humidity in the chamber can be controlled and kept constant during the reactions.

Contrast-enhanced endoscopic ultrasonography in digestive diseases

Journal of Gastroenterology, 2012
Contrast-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, 2011
On 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 ...

Enhanced resistance of DNA nanostructures to enzymatic digestion

Chemical Communications, 2009
The ability of nucleases to perform their catalytic functions depends on the sequence and structural features of target DNA substrates. Due to their size and shape, several DNA tetrahedra are resistant to the action of specific and non-specific nucleases.

Caffeine enhancement of digestion of DNA by nuclease S1

Mutation Research, 1976
The activity of Aspergillus orzae nuclease S1 on DNA has been investigated under varying pH and metal ion conditions. Nuclease S1 was found to preferentially digest denatured DNA. With native DNA as substrate the enzyme could only digest the DNA when caffeine was added to the reaction mixture. The enzyme was more active in sodium acetate buffer (pH 4.5)

Analysing the mechanisms of sludge digestion enhanced by iron

Water Research, 2017
Carbon-neutral operation of wastewater treatment plants (WWTPs) requires enhancing anaerobic digestion (AD) of excess sludge for a higher energy conversion efficiency. Among others, iron has been identified to function on enhancing methane production in AD.

Enhancement of methanogenic performance by gasification biochar on anaerobic digestion

Bioresource Technology, 2021
This work evaluates the performance of different biochar-amended anaerobic digestion systems. The Fourier Transform Infrared analysis showed that more ordered aromatic groups formed and the aromatization degree increased with the rise of gasification temperature. The biochar produced at 900 °C still showed an excellent ability to maintain the stability
