Hydrolysis of Sorghum (Broomcorn) in Diluted Hydrochloric Acid

Effective conversion of lignocellulosic material as renewable energy source has significant reflection on economic and environmental impact. Diluted acid hydrolysis at optimal condition was used to liberate fermentable sugar. The sorghum stalks, the alkali pretreatment of biomass and hydrolysis in diluted hydrochloric acid were investigated. The hydrolysis reaction was carried out in a 5L react...

Surface Chemical Compositions and Dispersity of Starch Nanocrystals Formed by Sulfuric and Hydrochloric Acid Hydrolysis

Surface chemical compositions of starch nanocrystals (SNC) prepared using sulfuric acid (H2SO4) and hydrochloric acid (HCl) hydrolysis were analyzed by X-ray photoelectron spectroscopy (XPS) and FT-IR. The results showed that carboxyl groups and sulfate esters were presented in SNC after hydrolysis with H2SO4, while no sulfate esters were detected in SNC during HCl-hydrolysis. TEM results showe...

Novel antiviral activity of dialdehyde starch

A significant effort worldwide is being directed toward development of novel biocides against drug-resistant bacterial and viruses because of the significant potential human infection risks in the general population. We report here the discovery of a strong antiviral biocide, dialdheyde starch (DAS). Antiviral tests were carried out against three non-envelop viruses, including two bacterial vir...

The effect of zinc-hydrochloric acid hydrolysis on the estrogens in human urine.

Smith and Smith (1) reported that boiling of human female urine for 3 hours with 4 gm. per cent of zinc dust and 15 volumes per cent of hydrochloric acid resulted in a marked increase of estrogen potency over that acquired by optimum conditions of simple acid hydrolysis; namely, 10 minutes boiling with 15 volumes per cent of hydrochloric acid. They were unable to account for all of the increase...

Bacterial Inactivation Kinetics of Dialdehyde Starch Aqueous Suspension

The bacterial inactivation kinetics of dialdehyde starch (DAS) aqueous suspension was studied by the relationship between the minimal lethal concentration (MLC) and the inactivation time at four different temperatures. The relationship between MLC and exposure time was found to follow the first-order Chick-Watson law. This first-order inactivation kinetics was modeled by pseudo-first order chem...
