Agri-food processing waste and by-products are important to be valued in an integral unit the main process. This study focused on showing potential valorization of apple pomace as substrate towards valuable products by a biotechnological mean. Apple was fermented B.subtilis at 37 °C, 150 rpm, 72 h. Reducing sugars, total phenol content α-amylase activity were followed throughout fermentation. T...

Jerusalem artichoke is a low-requirement crop, which does not interfere with food chain, and is a promising carbon source for industrial fermentation. Microbial conversion of such a renewable raw material to useful products, such as lactic acid, is an important objective in industrial biotechnology. In this study, high-optical-purity l-lactate was efficiently produced from the hydrolysates of J...

This work presents an automated analytical procedure for the photometric determination of reducing sugars in wines. The procedure is based on the reaction of reducing sugars with potassium hexacyanoferrate(III) in an alkaline medium, and was implemented employing a multicommuted flow analysis (MCFA) approach. Sample heating to promote the reaction was accomplished using a flow-batch device, whi...

Xylanase can be usd for many Industrial applications and juice clarification is one of them. Pseudomonas sp. xylanase was used for fruit juice clarification in free State. Maximum amount of juice clarification was in case of Mausambi juice was observed at 40 ̊C and 52 hours, in case of free enzyme treated juice there is 46.9% increase in clarity and 1.7 fold increase in reducing sugars of the ju...

In this work the possibility of producing vanillin through microbial bioconversion from ferulic acid obtained from the enzymatic hydrolysis of wheat bran has been explored. The biocatalyst employed was Escherichia coli JM109/pBB1, a recombinant strain containing the genes from Pseudomonas fluorescens BF13 for the transformation of ferulic acid into vanillin. The substrate of the bioconversion, ...

The levels of lipids, carbohydrates and enzymes concerned with their breakdown were determined in sesame (Sesamum indicum L.) seeds during an 8-days period of germination. Alkaline lipase and isocitrate lyase activities were at peak level when the lipid mobilization was highest. The content of total soluble carbohydrates, reducing and nonreducing sugars, increased during the initial 5-days peri...

The aim of this study is to investigate ionic liquids (ILs) pretreatment on kempas composition, structure and enzymatic digestibility. Ground kempas (Koompassia malaccensis) was pretreated with 1-butyl-3-methylimidazolium acetate ([Bmim][OAc]), 1-butyl-3-methylimidazolium chloride ([Bmim]Cl) and 1-butyl-3-methylimidazolium trifluoromethansulfonate ([Bmim][OTf]), at 120°C for 6 and 12 h. The cel...

The present work represents a comparative kinetic analysis of enzyme hydrolysis, using two kinetic variables to describe both reducing sugars and glucose. The preliminary treatment of wheat straw by steam explosion was followed by enzyme hydrolysis using the NS 50013 and β-glucosidase NS 50010 enzyme cellulase complex. The hydrolysis has been described by an exponential kinetic equation valid f...

The morphological and biochemical qualities of new potato varieties Belarusian selection for suitability the production crispy have been studied. influence content dry substances reducing sugars on indicators quality finished product has

The objective of this study was to evaluate the physico-chemical quality of honeys samples of stingless bee (Meliponinae). Physico-chemical analyses were: moisture, color, pH, acidity, electrical conductivity, hydroxymethylfurfural, ashes, diastasic activity, reducing sugars, and sucrose. For the parameters hydroxymethylfurfural, ashes, reducing sugars and sucrose, the samples complied with the...
