An investigation was carried out using rice straw as a low-cost substrate to study the optimization of xylanase production using a newly identified endospore-forming bacterium, Bacillus altitudinis RS3025. The highest xylanase activity was achieved using 2% rice straw (pretreated with 2% NaOH at 100 °C) at pH 7.0, 37 °C temperature, and with 72-h i...

To shorten the preparation time of porous starch while simultaneously ensuring its adsorption performance, we treated corn starch with a combination of microwave and complex enzymatic (α-amylase and amyloglucosidase) hydrolysis. Specifically, we investigated the effect of microwave and enzymatic hydrolysis on the structure, physicochemical properti...

Xylan is a renewable polysaccharide, readily available in agricultural and forestry residues. It can be hydrolyzed to produce xylooligosaccharides (XOS) with prebiotic activity and xylose, a precursor for several industrial chemicals. Enzymatic hydrolysis of xylan in the lignocellulosic biomass to obtain xylose and XOS requires a pretreatment to fa...

Excessive use of fossil fuels has accelerated climate change and global warming necessitates the need for renewable energy sources that have a lower environmental impact. In the recent decade, lignocellulosic biomass has become a prominent alternative to renewable energy resources for the production of bioenergy. The pretreatment procedure is consi...

Herein, a mild fractionation method by employing polyol-based Brønsted acidic DESs (BDESs) was proposed to extract lignin with well-preserved β-O-4 substructures and to enhance fermentable sugar yields simultaneously. For ethylene glycol-oxalic acid (EG-OA), more than 53 % of lignin was obtained and superb carbohydrate digestibility (i.e., glucose ...

Elastin is considered an excellent resource for obtaining antioxidant peptides due to unique amino acid composition. However, it is hardly soluble in water or in dilute acid or alkali; most of the elastases have low yields for preparing elastin peptides, making it difficult to meet industrial applications. To address above problems, enzymes capable...

Most studies about the influence of lignin on enzymatic digestibility of lignocellulose have focused on the content and properties, but less on the detaching behavior of lignin. The samples were prepared from Pinus massoniana wood chips by kraft cooking followed by delignification using oxygen/alkali (KP-O) and chlorine dioxide (KP-D), respectively...

Starch microspherical aerogel (SMA) prepared by enzymatic hydrolysis of starch with α-amylase was demonstrated to be higher adsorption capacity for methylene blue. Proper cleavage of α-1,4 glycosidic bonds could enhance the adsorption capacity of SMA, while the cleavage of α-1,6 glycosidic bonds showed an opposite effect. Compared with tapioca star...

Many xenobiotics were identified as possible endocrine disruptors during the last decades. Structural analogy of these substances to natural hormones may lead to agonists or antagonists of hormone receptors. For a comprehensive human biomonitoring of such substances, we developed a simple, reliable, and highly sensitive method for the simultaneous ...
