Objective(s): Today, consumers are looking for food products providing health benefits in addition to meeting the basic nutritional needs of the body. This study aimed to evaluate the antioxidant and cytotoxic effects of Liza klunzingeri protein hydrolysate both in vivo and in vitro.Materials and Methods: Fish protein hydrolysate (FPH) w...
Dried soy protein hydrolysate powder was added to the burger in order to enhance the oxidative stability as well as decreases the microbial spoilage. The soybean bioactive compounds (soy protein hydrolysate) as antioxidant and antimicrobial were added at level of 1, 2 and 3 %.Chemical analysis and physical properties were affected by protein hydrolysate addition. The TBA values were significant...
Xylitol production was compared in fed batch fermentation by Saccharomyces cerevisiae strains overexpressing xylose reductase (XR) genes from Candida tropicalis, Pichia stipitis, Neurospora crassa, and an endogenous gene GRE3. The gene encoding a xylose specific transporter (SUT1) from P. stipitis was cloned to improve xylose transport and fed batch fermentation was used with glucose as a cosub...
BACKGROUND Heavy usage of gasoline, burgeoning fuel prices, and environmental issues have paved the way for the exploration of cellulosic ethanol. Cellulosic ethanol production technologies are emerging and require continued technological advancements. One of the most challenging issues is the pretreatment of lignocellulosic biomass for the desired sugars yields after enzymatic hydrolysis. We h...
BACKGROUND Microbial conversion of lignocellulosic feedstocks into biofuels remains an attractive means to produce sustainable energy. It is essential to produce lignocellulosic hydrolysates in a consistent manner in order to study microbial performance in different feedstock hydrolysates. Because of the potential to introduce microbial contamination from the untreated biomass or at various poi...
Stichopus horrens flesh was explored as a potential source for generating peptides with angiotensin-converting enzyme (ACE) inhibitory capacity using 6 proteases, namely alcalase, flavourzyme, trypsin, papain, bromelain, and protamex. Degree of hydrolysis (DH) and peptide profiling (SDS-PAGE) of Stichopus horrens hydrolysates (SHHs) was also assessed. Alcalase hydrolysate showed the highest DH ...
The present study investigates approaches to enhance bio-butanol production using lignocellulosic feedstock via supplements of metabolism perturbation. Traditionally, has been produced through chemical synthesis in a process known as acetone–butanol–ethanol (ABE) fermentation. Today, biochemical techniques involving bacterial strains capable producing butanol are used with renewable sources bio...
2,3-butanediol (2,3-BDO) is a platform chemical that can be converted to wide array of products ranging from bio-based materials sustainable aviation fuel. This produced by variety microorganisms in fermentation processes. Challenges remain for high titer 2,3-BDO production during due several parameters, but controlling oxygen one the most relevant processing parameters ensure viable product ou...
Corncobs are a plentiful lignocellulosic material that can be utilized for energy production as well the generation of other high-value products. Within modern concept biorefineries, we present processes conducted in column reactor valorization corncobs substrate ethanol and xylitol production. In first step, were subjected to acid hydrolysis, resulting hemicellulosic hydrolysate rich xylose su...
