This study examined the effect of climate change (CC) abiotic factors of temperature (20, 25, 30 °C), water activity (aw; 0.995, 0.98) and CO2 exposure (400, 1000 ppm) may have on (a) growth, (b) gene expression of biosynthetic toxin genes (Tri5, Tri6, Tri16), and (c) T-2/HT-2 toxins and associ...

Ultrafiltration permeate of whey protein tryptic hydrolyzate was processed by nanofiltration (NF) to obtain retentate (NFR) and permeate (NFP) that were then tested as inhibitors of Listeria, Staphylococcus aureus and Escherichia coli. NFR at 20 mg mL−1 was most effective as an inhibitor (P

Compared to other inedible agricultural based feedstocks such as corn stover, rice husk, wheat straw and sugarcane bagasse, sorghum biomass (stalks and leaves) possess elevated credentials towards biofuel production which is highly tolerant against heat and drought conditions. Therefore, a novel...

Enzymatic hydrolysis of proteins frequently results in bitter taste, which is due to the formation of low molecular weight peptides composed of mainly hydrophobic amino acids. Methods for debittering of protein hydrolyzates include selective separation such as treatment with activated carbon, ex...

An extensive protein hydrolyzate was produced starting from sunflower defatted seed meal, an abundant by-product of biodiesel chain oil extraction. Two-step enzymatic hydrolysis was carried out using sequentially Alcalase-Flavourzyme enzymes and a high quality hydrolyzate was produced with an in...

Live yeast cultures and yeast hydrolyzates can be used as rumen fermentation modifiers, but their effects and mode of action are different. Whereas the effects of live yeast cultures on rumen fermentation are well documented, yeast hydrolyzates have received much less attention. The influence of...

There is growing interest in recovering ferulic acid from plant sources for use as feedstock for several high-value applications. Jojoba meal was examined as a potential source of ferulic acid. The feruloyl esterase domain of the Clostridium thermocellum cellulosomal xylanase was employed to hyd...

SummaryJojoba (Simmondsia chinensis L.) single node explants were cultured in a basal medium supplemented with 17.8 μM 6-benzyladenine and four levels of sodium chloride concentration (0, 56.41, 112.82 and 169.23 mM). The free, the soluble conjugated and the insoluble bound forms of polyamines ...

Troponin I (TnI) is the inhibitory subunit of the troponin complex in the sarcomeric thin filament of striated muscle and plays a central role in the calcium regulation of contraction and relaxation. Vertebrate TnI has evolved into three isoforms encoded by three homologous genes: TNNI1 for slow...

Myoglobins (Mb) are ubiquitous proteins found in striated muscle of nearly all vertebrate taxa. Although their function is most commonly associated with facilitating oxygen storage and diffusion, Mb has also been implicated in cellular antioxidant defense. The oxidized (Fe3+) form of Mb (metMB) ...

The aim of this study was to assay changes in blood biochemical parameters that resulted from exercise-induced muscle fatigue in horses participating in the two races (1,250 and 1,400 meters). Six male Arabian horses (3 to 6 years old) were used in this study. Blood samples were collected at tim...

Insight in the link between foaming and interfacial properties of proteins can increase their potential as functional agents in food systems. Here, foaming capacity and stability of structurally different peptic and tryptic wheat gluten hydrolyzates were related to the kinetics of their adsorpti...

Soy protein hydrolyzate has been used as supplements in wheat flour to enhance the nutritional value of its products, but it may negatively affect the gluten properties simultaneously. In order to explore the mechanism of this effect, protein characteristics including disulfide bond, protein com...

In this work, a sensitive capillary electrophoresis method with laser induced fluorescence detection for determination of malondialdehyde in various biological fluids was developed. Malondialdehyde reacts with thiobarbituric acid under optimized conditions of pH=2, reaction time of 60 min and te...

A 4-step synthesis of an optically active synthetic intermediate [(1R,2S)-2-(4′-fluorobenzylamino)cyclopentanecarboxylic acid ethyl ester complex with (S)-(+)-mandelic acid; compound 12, >99% de] required for the preparation of a promising HCV NS5B polymerase inhibitor is reported. This process...

The stereoisomers of cis-2-halocycloalkanols were resolved by a kinetically controlled transesterification with vinyl acetate in the presence of lipases in organic media. High enantioselectivities (ee >98%) and good isolated yields were obtained for all substrates using the appropriate lipase. B...

Purpose of the research was to determine the activity of chiral imine ligands prepared from (1S,2R)-norephedrine for the enantioselective addition of diethylzinc to aldehydes. Imine ligands reveal medium enantioselectivity, with the ee exceeding 30%. The highest ee (97%) was obtained for imine w...

Derivatives were prepared from N-linked glycans by reductive amination from 2-aminobenzamide, 2-aminopyridine, 3-aminoquinoline, 2-aminoacridone, 4-amino-N-(2-diethylaminoethyl)benzamide, and the methyl, ethyl, and butyl esters of 4-aminobenzoic acid. Their electrospray and collision-induced dis...

We report here a carbonate-free electrolyte for lithium-ion batteries with low flammability which consist of lithium bis(fluorosulfonyl)imide (LiFSI) and 2-methylglutaronitrile (MGN) (LiFSI/MGN). LiFSI/MGN enables reversible lithium ion intercalation into graphite without any additives or co-sol...

Seven new triterpenoids, ganoderic acid T, ganoderic acid S, ganoderic acid R, ganoderic acid P, ganoderic acid Q, ganoderic acid 0, 7-O-methyl-ganoderic acid 0 and a known ergosterol derivative, ergosta-4,7,22-triene-3,6-dione were isolated from the cultured mycelium of Ganoderma lucidum. The s...
