Bioethanol fuel has the advantage of being more environmentally friendly than petroleum. is made from organic materials containing glucose. Baking rice contains 83.19% (w/w) carbohydrates and 29.70% amylose which can be converted into bioethanol through hydrolysis fermentation stages. This type research an experimental research, initial stage carried out to obtain reducing sugars using crude Ba...

The development of more efficient utilization of biomass has received increased attention in recent years. Cellulases play an important role in processing biomass through advanced biotechnological approaches. Both the development and the application of cellulases require an understanding of the activities of these enzymes. A new method to determine the activity of cellulase has been developed u...

Abstract Background Cocrystallization is one of the crystal engineering strategies used to alter physicochemical properties drugs that are poorly water-soluble. Gliclazide (GLZ), an antidiabetic drug, belongs Biopharmaceutical Classification System class-II (low solubility and high permeability) has low bioavailability, resulting in poor therapeutic effects patients. Therefore, impart better bi...

This study aimed to optimize the medium compositions and cultural conditions for improved chitinase production by a potential strain of Bacillus isolated from marine environment determine antifungal activity its against plant pathogenic fungi. Five isolates were cultured submerged fermentation using colloidal chitin in liquid medium. In this study, was determined measuring reducing sugars, whic...

Several representative ionic liquids (ILs) were synthesized, and [Emim]OAc was chosen as environment-friendly solvent for enzymatic in situ saccharification in view of its biocompatibility with both natural and microcrystalline cellulose, as well as its enzymatic activity. With the microwave pretreatment of natural and microcrystalline cellulose, directly enhancing the in situ enzymatic sacchar...

Silver nanoparticles were prepared by using alkali treated maize starch which plays a dual role as reducer for AgNO3 and stabilizer for the produced AgNPs. The redox reaction which takes a place between AgNO3 and alkali treated starch was followed up and controlled in order to obtain spherical shaped silver nanoparticles with mean size 4-6 nm. The redox potentials confirmed the principle role o...

Dinitrosalicylic acid was introduced by the author in 1921 as a reagent for the estimation of sugar in normal and diabetic urine.1 It has also been found to be a valuable reagent for the detection of aIbumin in urine and has been used for the determination of the titratable alkali of the blood.2 During the past 3 years several improvements have been made in the method for the determination of s...

In this study, the potential for a collection of wild-type L. lactis strains to metabolize breakdown products lignocellulose was investigated. The strains, isolated from variety environmental sources including grass and vegetables, were analyzed their ability ferment pentose sugars cellulolytic ability. total, 21 environment-derived evaluated. Eleven isolates found have commonly produced by bre...

Greenwald and Lewman (1) described a method in which the protein and carbonic acid of blood are removed by picric acid, so that the alkali of the proteinates and bicarbonate is replaced by an equivalent of alkali picrate, which is measured. The picric acid precipitates the protein and frees the COZ, which is boiled off from the filtrate. The alkali picrate is measured as total picric acid minus...

Amylases are considered the most essential enzymes in biotechnology since they widely utilized textile, food processing, and detergent industries. It is necessary to explore extracellular enzymatic activity several microorganisms discover a new potential application from amylases. In previous study, thermophilic bacteria Geobacillus sp. DS3 isolated Sikidang Crater, Dieng Plateau, Central Java,...
