Background and Objective: Hydrolysis of fat, oil and grease by ultrasonic waves is a pre-treatment method before anaerobic digestion which can change their physical, chemical and biological properties. The main purpose of this study was to investigate the efficiency of ultrasonic waves to improve the hydrolysis process and its use as an auxiliary substrate to increase the efficiency of anaerobi...

Glycyrrhiza glabra residue (GGR) was efficiently subjected to concentrated phosphoric acid (PA) pretreatment with/without surfactant assistance, and promising results were obtained following separate enzymatic hydrolysis and fermentation (SHF) of the biomass. Pretreatment was carried out using 85 % PA either at 50 or 85 °C with 12.5 % solid loading for 30 min. In parallel experiments, ...

In this investigation, the effects of commercial enzyme preparation containing alpha amylase and neutral protease on hydrolysis of excess sludge and the kinetic analysis of hydrolysis process were evaluated. The results indicated that amylase treatment displayed higher hydrolysis efficiency than that of protease. VSS reduction greatly increased to 39.70% for protease and 54.24% for amylase at t...

The 85 kDa human cytosolic phospholipase A2 has been cloned and expressed in insect Sf21 cells. The pure enzyme has been investigated using a fluorescence displacement assay that provides a continuous record of phospholipid hydrolysis [Wilton (1990) Biochem. J. 266, 435-439]. The unusual kinetic properties of this enzyme, previously described using radioactive assays, were readily demonstrated ...

BACKGROUND During cellulosic ethanol production, cellulose hydrolysis is achieved by synergistic action of cellulase enzyme complex consisting of multiple enzymes with different mode of actions. Enzymatic hydrolysis of cellulose is one of the bottlenecks in the commercialization of the process due to low hydrolysis rates and high cost of enzymes. A robust hydrolysis model that can predict hydro...

Urea hydrolysis is widely used in agriculture, environment and other engineering fields, among which urease contained beans can catalyze urea hydrolysis. The activity of legume plant leaching solution (LPLS) was investigated, including soybeans, black beans, mung red as well soybean hulls, leaves, stems pods. For the high economic efficiency, most suitable for agricultural fields than soybean-r...

Suitably configured allyl ethers of unsaturated cyclitols act as substrates β-glycosidases, reacting via allylic cation transition states. Incorporation halogens at the vinylic position these carbasugars, along with an activated leaving group, generates potent inactivators β-glycosidases. Enzymatic turnover halogenated (F, Cl, Br) displayed a counter-intuitive trend wherein most electronegative...

Enzyme efficiency was investigated in the lipase-catalyzed hydrolysis of canola oil in supercritical carbon dioxide (SCCO2). Immobilized lipase from Mucor miehie (Lipozyme IM) was used as the catalyst and the results showed that enzyme efficiency dropped at high pressures indicating a possible change in enzyme microstructure. Therefore, scanning electron microscopy (SEM) was used...
