Spectrophotometric determination of the hydrolysis of fluorescein diacetate (FDA) was shown to be a simple, sensitive, and rapid method for determining microbial activity in soil and litter. FDA hydrolysis was studied in soil and straw incubated for up to 3 h. Hydrolysis was found to increase linearly with soil addition. FDA hydrolysis by pure cultures of Fusarium culmorum increased linearly wi...
The present work deals with enzymatic hydrolysis of sweet sorghum bagasse to fermentable sugars. The bagasse was treated with phosphoric acid and sodium hydroxide prior to enzymatic hydrolysis by commercial cellulase and β-glucosidase. The phosphoric acid pretreatment was performed at 50°C for 30 min, while 12% NaOH was used for the alkali treatment at 0°C for 3 h. The phosphoric acid pretreatm...
Organic solvent, Enzymatic Hydrolysis, Cellulose, Acceleration Effect, Glucose Yield Effect of organic solvents on enzymatic hydrolysis of celluloses was studied. It was found that toluene and xylene can accelerate the rate of the enzymatic hydrolysis reaction of filter paper and cellulose powder. The addition of N,N-dimethylformamide, acetone, and alcohols was negative effect for the enzymatic...
1. Most of the products of the peptic hydrolysis of albumin, about 85 per cent of the total N, are primary in the sense that they arise directly from the protein molecule, and undergo no further hydrolysis. 2. A slow secondary hydrolysis, involving about 15 per cent of the total N, occurs in the proteose and simpler fractions primarily split off. 3. Acid metaprotein in peptic hydrolysis arises ...
This study was to determine the functional properties of fish protein hydrolysis produced from tilapia frame. used a factorial design where first factor different types proteolytic enzymes (E1 = bromelain, E2 papain) and second time (T1 5 hours, T2 6 hours) carried out with 3 replications. The results analysis showed that had significant difference on yield, degree hydrolysis, proximate, viscos...
Enzymatic hydrolysis of pre-treated wheat straw has been studied. Several additives have checked as potential improvers glucose yield in the enzymatic hydrolysis, trying to avoid cellulases inhibition by lignin a cause decrease saccharification rate lignocellulosic biomass. Non-ionic surfactants, such Tween 80 (poly(oxyethylene)20-sorbitan-monooleate) and polyethylene glycol-6000, proteins, bov...
Cobalt-catalyzed hydrolysis of sodium borohydride (NaBH(4)) has attracted great attention since the hydride is believed to be promising hydrogen storage material. Cobalt is an efficient metal catalyst and has already proven to be a potential alternative to noble metals. Nevertheless it is not stable. Indeed it transforms into a Co- and B-based material when on contact with NaBH(4). Through ex s...
Apoptosis, a form of cell death that is coordinated by a set of defined biochemical pathways, exists throughout the animal kingdom. Its critically important roles in development, homeostasis, and disease have made this a topic of intensive research and sometimes even more intensive controversy. One of these areas of controversy concerns the role of ceramide, produced by the hydrolysis of sphing...
BACKGROUND Due to the complexity of lignocellulosic materials, a complete enzymatic hydrolysis into fermentable sugars requires a variety of cellulolytic and xylanolytic enzymes. Addition of xylanases has been shown to significantly improve the performance of cellulases and to increase cellulose hydrolysis by solubilizing xylans in lignocellulosic materials. The goal of this work was to investi...
