Quinoa protein concentrate was hydrolyzed with alcalase to obtain a hydrolysate that was fractionated by ultrafiltration using 10000and 5000-molecular-weight cutoff membranes. Functional properties of the protein concentrate, protein hydrolysate, and membrane permeates were compared at different pH values. Protein solubility of the hydrolysate and membrane permeates were significantly higher (P...

anzali lagoon can be one of the most important wetlands called the world. this lagoon to support the most fish in the caspian sea is reproduced for the spawn, multiply, and sometimes live, to make the pond.much of rasht and anzali city sewage and agricultural waste area of the lagoon through rivers into the pyrbazar and increased levels of organic pollutants such as nitrite, nitrate, phosphate,...

Introduction Seafoods are inherently functional and possess many components that are good for human health. Seafoods and their by-products are an excellent source of nutraceuticals and bioactives, and these can be extracted/isolated and added to a range of foods thereby enhancing functionality of the foods in terms of human health (Shahidi, 2003; Alasalvar and Taylor, 2002). These aspects are a...

Highlight Research Snakehead fish head possess high protein content and potential to be used as materials for hydrolysate hydrolysis optimum condition were determined antioxidant activity analyzed is Abstract There concern regarding the use of synthetic antioxidants which spurred yearly increase natural substitute ones. Fish (FPH), has been reported have potent properties, could utilized solve ...

Establishing a commercial, lignocellulose-based, second-generation ethanol process has received several decades of attention by both researchers and industry. However, a fully economically viable process still remains a long-term goal. The main bottleneck to this achievement is the recalcitrance of lignocellulosic feedstocks, although there are several other factors, such as the huge investment...

A flow system was developed for the determination of total mercury concentration in fish samples by cold vapor atomic absorption spectrophotometry (CVAAS), based on the multicommuted flow injection analysis (MCFIA) approach. The system uses independently controlled solenoid valves for the introduction of reagents and samples. When not injected, solutions were recirculating to the reservoir bott...

The purpose of this study was to explore the possibility replacing an expensive yeast extract contained in fermentation medium for D-lactic acid (D-LA, R-lactic acid) biosynthesis with alternative nitrogen source. screening studies were conducted under stationary conditions and showed that pea seed hydrolysate most beneficial substrate process D-LA by strain Sporolactobacillus laevolacticus DSM...

The efficient production of biofuels from cellulosic feedstocks will require the efficient fermentation of the sugars in hydrolyzed plant material. Unfortunately, plant hydrolysates also contain many compounds that inhibit microbial growth and fermentation. We used DNA-barcoded mutant libraries to identify genes that are important for hydrolysate tolerance in both Zymomonas mobilis (44 genes) a...
