Abstract Corncobs are composed of cellulose, hemicellulose, and lignin. Cellulose hemicellulose monomeric sugars that can be utilized as carbon sources for microbial growth bioproduct formation. However, corncobs present several challenges due to their complex recalcitrant nature. Addressing these increased enzymatic accessibility requires pretreatment methods break down resistant structures, t...

Background: Bread is the major waste product worldwide. It contains a considerable amount of starch, which easily converted into sugars using enzymes. The aim this study was to produce fermentable from stale bread barley malt as substitute commercial Methods: Response surface methodology based on Box-Behnken design applied optimize parameters enzymatic hydrolysis such content (1.25, 2.5 and 3.7...

The interest of supplying lignocellulosic materials for producing fermentable sugars has recently emerged in order to diminish the negative environmental effects fossil fuels. In this study, Ulmus minor clone Ademuz, characterized its tolerance Dutch elm disease and rapid growth, was evaluated as a source sugars. For that, different pretreatments, comprising autohydrolysis, dilute acid hydrolys...

Cellulose is a major renewable form of carbohydrate, with approximately 1011 tons synthesized annually. It is an unbranched β-1,4-linked homopolymer of glucose [1], but cellulose samples of different origins vary widely in their chain lengths and in the degrees of interaction between chains. As a raw material, cellulose has currently the greatest potential to produce bioethanol; however, cellul...

INTRODUCTION Present and future world shortages and increasing petroleum costs have stimulated the search for alternate renewable and nonrenewable energy sources. Sugarbeets (Beta vulgaris L.) and sugarcane (Saccharum app.) have high potential as a feedstock for conversion to alcohol as a practical renewable energy source. Sugarbeets have many desirable characteristics such as: storage of 40 to...

A dynamic relation exists between sugars and oral health. Diet affects the integrity of the teeth; quantity, pH, and composition of the saliva; and plaque pH. Sugars and other fermentable carbohydrates, after being hydrolyzed by salivary amylase, provide substrate for the actions of oral bacteria, which in turn lower plaque and salivary pH. The resultant action is the beginning of tooth deminer...
