In this study, the efficacy of biochar to mitigate ammonia stress and improve methane production is investigated. Chicken manure (CM) was subjected high-solid mesophilic anaerobic digestion (15% total solid content) with wood (BC). Wood further treated using HNO3 NaOH produce acid–alkali-treated (TBC), an improvement in its overall ammonium adsorption capacity porosity. Three treatments were lo...

The speed of protein digestion impacts on postprandial protein anabolism. After exercise or in the elderly, fast proteins stimulate protein synthesis more efficiently than slow proteins. It has been shown that meat might be a source of fast proteins. However, cooking temperature, acting on the macrostructure and microstructure of the meat could affect both the speed, and efficiency, of protein ...

Seaweed is a promising sustainable source of vegan protein as its farming does not require arable land, pesticides/insecticides, nor freshwater supply. However, to be explored novel the content and nutritional quality in seaweed need improved. We assessed influence pH-shift processing on degree hydrolysis (%DH), protein/peptide size distribution, accessibility, cell bioavailability Ulva fenestr...

Mild digestion of isolated adipose tissue cells with Closfridium perjringens neuraminidase (10 to 20 mpg of purified enzyme per ml, 15 min at 37”) results in enhanced glucose transport by these cells. This effect appears to mimic closely the physiological effect of insulin on glucose transport by normal cells, and there is evidence to suggest that these two apparently different stimuli may affe...

The identification of disulfide bonds provides critical information regarding the structure and function of a protein and is a key aspect in understanding signaling cascades in biological systems. Recent proteomic approaches using digestion enzymes have facilitated the characterization of disulfide-bonds and/or oxidized products from cysteine residues, although these methods have limitations in...

Thirty peptides obtained from the tryptic digestion of oxidized staphylococcal enterotoxin B were isolated chromatographically on columns of Dowex SOW-X2 and AGl-X2 by using pyridine-acetic acid and N-ethylmorpholine-pyridine-acetic acid buffer systems. The isolated peptides were further purified by paper chromatography and electrophoresis. The amino acid composition and sequence of each purifi...

Dietary proteins are known to contain bioactive peptides that are released during digestion. Endogenous proteins secreted into the gastrointestinal tract represent a quantitatively greater supply of protein to the gut lumen than those of dietary origin. Many of these endogenous proteins are digested in the gastrointestinal tract but the possibility that these are also a source of bioactive pept...

The aim of this study was to evaluate the effect of inclusion of tannic acid on some performance traits and nutrient digestibility in Holstein dairy calves. A total of 20 seven days old Holstein calves were randomly assigned to 4 experimental treatments with 5 calves each. The treatments were as follows: 1) basal diet formulated to meet all nutritional requirement of calves according to NRC (20...

anaerobic digestion is a feasible technology to stabilize the solid waste generated inslaughterhouses obtaining significant quantities of biogas, considered as a clean and renewable fuel. this iswhy it is important to optimize the digestion process in order to eliminate organic matter and maximize theproduction of biogas. in this work, a system was developed for treating slaughterhouse solid wa...

enzymatic extract preparation from pseudomonas aeruginosa km110 under accession no. hq730879 with lipase activity (0.3 u/ml), was used to perform enzymatic hydrolysis pretreatment of a synthetic dairy wastewater with 1000 mg/l total fat content. the pretreatment was optimized for 48 h hydrolysis time, at 45æ% c with 10% v/v enzymatic extract. the biological treatment of synthetic dairy wastewat...
