BACKGROUND During the pretreatment of biomass feedstocks and subsequent conditioning prior to saccharification, many toxic compounds are produced or introduced which inhibit microbial growth and in many cases, production of ethanol. An understanding of the toxic effects of compounds found in hydrolysate is critical to improving sugar utilization and ethanol yields in the fermentation process. I...

was first shown by Henrique and Andersen (1913). Elman and Lischer (1943) administered large amounts of amino-acids and peptides intravenously to men without any ill effects. They were able thus to maintain nitrogen equilibrium in patients who could not take food by mouth. Bassett et al. (1944) report a study of a patient with gastro-jejuno-colic fistula, who was given solutions of amino-acids ...

This study was designed to compare the acute response of mixed muscle protein synthesis (MPS) to rapidly (i.e., whey hydrolysate and soy) and slowly (i.e., micellar casein) digested proteins both at rest and after resistance exercise. Three groups of healthy young men (n = 6 per group) performed a bout of unilateral leg resistance exercise followed by the consumption of a drink containing an eq...

BACKGROUND The major types of commercially available gelatin hydrolysates are prepared from mammals or fish. Dietary gelatin hydrolysates from mammals were reported to improve bone mineral density (BMD) in some animal models. In contrast, there is limited study showing the effects of dietary gelatin hydrolysates from fish on BMD. The quantity and structure of peptides in the plasma after oral a...

BACKGROUND The aim of the study was to determine the effect of pasteurisation and sterilization of model systems of minced chicken meat in the presence of low or high-oxidised pork lard, soy and sunflower oil, as well as casein hydrolysate and rosemary extract, on losses of thiamine in model systems. METHODS In the samples, the thiamine content was analysed periodically by thiochromium method...

BACKGROUND The transition from a petroleum-based economy towards more sustainable bioprocesses for the production of fuels and chemicals (circular economy) is necessary to alleviate the impact of anthropic activities on the global ecosystem. Lignocellulosic biomass-derived sugars are suitable alternative feedstocks that can be fermented or biochemically converted to value-added products. An exa...

This study aims at preparing the Maillard reaction products of protein hydrolysate from grass carp (Ctenopharyngodon idella) bone and identifying its characteristic flavour compounds. Meanwhile, bioactivities amino acids composition hydrolysates were compared with thermal degradation as one positive control. Single factor experiment was applied to optimize enzymolysis parameters using flavourzy...

This study was carried out to evaluate the efficiency of natural protease extracted from starfruit (Averrhoa carambola. L) to hydrolyse green mussel (Perna viridis). Starfruit juice from fruit of maturity index 2 was extracted and purified using acetone precipitation method. The obtained protease was then used to hydrolyse green mussel and compared with alcalase. The conditions used to produce ...

Nonsteroidal anti-inflammatory drugs (NSAID) are associated with gastrointestinal inflammation and subsequent damage to the intestinal tissue. Earlier studies in our laboratory have found that specific casein hydrolysates (CH) might be useful in the treatment of gastrointestinal wounds. The underlying mechanisms that support inflammation and wound healing are not completely understood, but tran...
