This work aims to utilize wastes from the potato starch industry to produce single-cell protein (SCP) with high lysine content as animal feed. In this work, S-(2-aminoethyl)-L-cysteine hydrochloride-resistant Bacillus pumilus E1 was used to produce SCP with high lysine content, whereas Aspergillus
We purified and compared the polyphenol oxidase (PPO) isoenzymes present in "Xushu 22," a sweet potato. A membrane-bound form (mPPO) and two soluble forms (sPPO1 and sPPO2) were identified and purified using ammonium sulphate precipitation, ion exchange chromatography, gel filtration chromatography,
There is currently no authorized or established therapeutic level/dose of probiotics for proposed health benefits; however, a daily probiotic consumption of 108 to 1010 CFU has been recommended. This study determined the survival of 5 individual probiotic strains, Lactobacillus rhamnosus,
Dietary acrylamide is largely derived from heat-induced reactions between the amino group of the free amino acid asparagine and carbonyl groups of glucose and fructose during heat processing (baking, frying) of plant-derived foods such as potato fries and cereals. After consumption, acrylamide is
Nitric oxide (NO) has various functions in physiological responses in plants, such as development, hormone signaling and defense. The mechanism of how NO regulates physiological responses has not been well understood. Protein S-nitrosylation, a redox-related modification of cysteine thiol by NO, is
The role of ethylene in embryogenesis of cultured potato anthers was studied indirectly by testing various substances known to affect ethylene formation. The reducing agents ascorbic acid and L-cysteine prevented browning of anther cultures and significantly stimulated embryogenesis. Embryogenesis
The possible role of arginine in the mechanism of muscle glycogen phosphorylase qas studied by examining the effect of arginine compounds. Guanidino compounds with an aromatic group inhibit native phosphorylase b, reduced phosphorylase b, phosphorylase b', and phosphorylase a. The inhibition was
Acrylamide is classified as a probable carcinogen to humans and generated from Maillard reaction. Currently, the short-term exposure to acrylamide was evaluated via external diet sources in vitro or two main mercapturic acid metabolites: N-acetyl-S-(2-carbamoylethyl)-L-cysteine (AAMA) and
Proteolytic activities in alfalfa weevil (Hypera postica) larval midguts have been characterized. Effects of pH, thiol activators, low-molecular weight inhibitors, and proteinase inhibitors (PIs) on general substrate hydrolysis by midgut extracts were determined. Hemoglobinolytic activity was
Fresh-cut potatoes were treated with an antibrowning solution (l-cysteine-citric acid mixture) and chlorine solutions, and then packaged under a modified atmosphere. The effect of these treatments on the microbiology of the potatoes was evaluated. Dipping the potato strips in sodium hypochlorite
OBJECTIVE
To assess exposure of commercial application workers to the nematocide cis-1,3-dichloropropene (cis-DCP).
METHODS
The study was conducted during the annual application season, August to 15 November, in the starch potato growing region in The Netherlands. 14 Application workers collected
A simple defined solid medium containing citrate and succinate, three amino acids (L-glutamine, L-asparagine, and L-cysteine), hemin chloride, potato starch, gellan gum (GelRite), and mineral salts supported the growth of grape strains of Xylella fastidiosa, the bacterial pathogen that causes
The growth of proteolytic Clostridium botulinum from spore inocula and changes in spore counts in mushroom, broccoli, and potato purées were monitored. Four strains of proteolytic C. botulinum types A and B were inoculated separately at approximately 10(4) spores per ml in nutrient broth and
Polyphenolic antioxidants may effectively reduce acrylamide contents in processed foods. However, few studies focused on their detoxification effects via estimating the profile change of internal exposure biomarkers. Here we showed the protective effect of a water-soluble flavone-C-glycoside-rich
