To optimally convert corn hull, a byproduct from corn processing, into bioethanol using Pachysolen tannophlius, we investigated the optimal conditions for hydrolysis and removal of toxic substances in the hydrolysate via activated carbon treatment as well as the effects of this detoxification process on the kinetic parameters of bioethanol production. Maximum monosaccharide concentrations were ...

Acetaminophen is a commonly used analgesic. However, an overdose of acetaminophen causes severe hepatotoxicity via depletion of hepatic glutathione. Here, we investigated the protective effects of sake lees hydrolysate against acetaminophen-induced hepatotoxicity in mice. Sake lees hydrolysate was administered orally to ICR mice for seven days. Six hours after acetaminophen treatment, the mice ...

In a previous study (Kindt et al. 1983, 1984) it was assumed that a protein hydrolysate, devoid of phenylalanine, together with intact protein as given to children with phenylketonuria (PKU), was equivalent to egg or milk protein. One group of children was given this 'PKU protein' in amounts corresponding to the Joint FAO/WHO ad hoc Expert Committee (1973) recommendations. The results indicated...

Cerebroprotein hydrolysate is an extract from porcine brain tissue that acts on the central nervous system in various ways to protect neurons and improve memory, attention, and vigilance. This study examined the effect and mechanism of cerebroprotein hydrolysate on learning and memory in mice with scopolamine-induced impairment. Mice were given an intraperitoneal injection of scopolamine hydrob...

A bovine alpha s1-casein tryptic hydrolysate was previously demonstrated to display an anxiolytic-like activity in the conditioned defensive burying and in the elevated plus-maze models when i.p. injected. The present study assessed the anxiolytic-like effects of this tryptic hydrolysate after an oral administration in rats faced to the same behavioural situations using diazepam as a reference....

Functional properties and antioxidative activity of a protein hydrolysate prepared from Acanthogobius hasta processing by-product protein during solid-state fermentation with Aspergillus oryzae were investigated. Overall, protease activity increased with the degree of hydrolysis (DH) decreased during solid-state fermentation. All the protein hydrolysate had excellent solubility, possessed inter...

Snyder, Irvin S. (University of Iowa, Iowa City), and Nancy A. Koch. Production and characteristics of hemolysins of Escherichia coli. J. Bacteriol. 91:763-767. 1996.-Filterable and nonfilterable hemolysins were produced by Escherichia coli in beef-heart infusion, casein hydrolysate, and chemically defined media. Differences were found among the three media in the time of appearance and in the ...

Papain was used to prepare a casein hydrolysate with a degree of hydrolysis of 9.4 %. The hydrolysate had the in vitro antioxidant activity with a DPPH radical scavenging activity of 38.7 % and an EC50 of 1.63 mg/mL. Extrinsic phenylalanine or tyrosine was added to the hydrolysate for a papain-catalyzed plastein reaction. The temperature, substrate mass per volume fraction, and the levels of en...

UNLABELLED A major obstacle to sustainable lignocellulosic biofuel production is microbe inhibition by the combinatorial stresses in pretreated plant hydrolysate. Chemical biomass pretreatment releases a suite of toxins that interact with other stressors, including high osmolarity and temperature, which together can have poorly understood synergistic effects on cells. Improving tolerance in ind...

Nine healthy volunteers were divided into a test group (n = 5) and a control group (n = 4). The test group consumed 3 grams per d of wheat gluten hydrolysate for 6 d, and their NK cell activity and hematological parameters were measured: The same assessments were performed in the control group, which did not receive wheat gluten hydrolysate. In the test group, NK cell activity increased signifi...
