Sodium hydroxide pretreatment and enzymatic hydrolysis of coastal Bermuda grass.
Coastal Bermuda grass was pretreated with NaOH at concentrations from 0.5% to 3% (w/v) for a residence time from 15 to 90min at 121 degrees C. The pretreatments were evaluated based on total lignin removal and production of total reducing sugars, glucose and xylose from enzymatic hydrolysis of the pretreated biomass. Up to 86% lignin removal was observed. The optimal NaOH pretreatment condition...
متن کاملFermentation characteristics and nutritional value of ruminal contents and blood ensiled with untreated or sodium hydroxide-treated wheat straw.
Bovine ruminal contents and blood were ensiled with wheat straw, either untreated or treated with 4% NaOH (DM basis), with and without addition of 5% dry molasses. Proportions of ruminal contents, blood, and straw were 45:15:40, wet basis, respectively. Wheat straw also was ensiled alone, and water was added to attain 43% DM. After 60 d, all silages had a desirable aroma. The pH of the ensiled ...
متن کاملCaustic skin burn caused by sodium hydroxide.
DESCRIPTION A 75-year-old, previously healthy, woman presented to the emergency room with bilateral hand wounds. Her medical history revealed the use of a sodium hydroxide (NaOH)—impregnated swab without gloves for approximately 2–3 h. Within several hours she felt a burning sensation and noticed significant hyperaemia and blisters over her left interdigitals and her right tenar eminence and fi...
متن کاملinvestigation of chemical pretreatment of rice straw with ammonia, urea and sodium hydroxide
agricultural residues have high potential to produce biogas, but they contain lignocellulosicmaterials which are not easily degradable, so the pretreatment is required. chemical pretreatmentincreases the rate of degradation and efficiency of biogas production. this study has beeninvestigated the effect of 4% -urea, 5%-ammonia and 8%-sodium hydroxide on degradation of ricestraw and production of...
متن کاملLeaching Kinetics of Stibnite in Sodium Hydroxide
Spherical pellets of antimony sulphide were dissolved in 1 molar sodium hydroxide solutions at different temperatures. It was found that the shrinking core with ash layer model could satisfactorily explain the dissolution process. Using this model it was found that initially the rate controlling step is a chemical reaction with activation energy of 10.2 kJ/mol. As the ash layer builds up, diffu...
