Sediments in coffee extracts: Composition and control by enzymatic hydrolysis.

Food chemistry

Delgado PA, Vignoli JA, Siika-Aho M, Franco TT.
PMID: 26050180
Food Chem. 2008 Sep 01;110(1):168-76. doi: 10.1016/j.foodchem.2008.01.029. Epub 2008 Jan 31.

The water-insolubility of some coffee extract components is one of the major limitations in the production of instant coffee. In this work, fractions from coffee extracts and sediments were prepared, and their chemical composition determined. Based on the carbohydrate...

Starchy agricultural wastes were inoculated with amylolytic yeasts for protein enrichment by solid-state fermentation. The moisture content of substrate was 65-69%, and water activity was equivalent to 0.98-0.99. The optimum conditions for protein enrichment were initial moisture content 65%,...

Improving High-resolution Impedance Manometry Using Novel Viscous and Super-viscous Substrates in the Supine and Upright Positions: A Pilot Study.

Journal of neurogastroenterology and motility

Wong U, Person EB, Castell DO, von Rosenvinge E, Raufman JP, Xie G.
PMID: 30122029
J Neurogastroenterol Motil. 2018 Oct 01;24(4):570-576. doi: 10.5056/jnm18010.

BACKGROUND/AIMS: Swallows with viscous or solid boluses in different body positions alter esophageal manometry patterns. Limitations of previous studies include lack of standardized viscous substrates and the need for chewing prior to swallowing solid boluses. We hypothesize that high-resolution...

Antiviral Properties of .

Pakistan journal of biological sciences : PJBS

Zainab Mazhari BB.
PMID: 35001579
Pak J Biol Sci. 2022 Jan;25(1):90-99. doi: 10.3923/pjbs.2022.90.99.

Background and Objective: The proposed study involves the approach from the point of anti-viral activity of gold nanoparticles against the Bluetongue virus. Among viral diseases, Bluetongue is regarded as an economically scouring disease. Neither a vaccine nor an antiviral...

Optimisation of enzymatic saccharification of wheat straw pre-treated with sodium hydroxide.

Scientific reports

Wang Z, Wu S, Fan C, Zheng X, Zhang W, Wu D, Wang X, Kong H.
PMID: 34853397
Sci Rep. 2021 Dec 01;11(1):23234. doi: 10.1038/s41598-021-02693-2.

To enhance the reducing sugar yield in enzymatic hydrolysis, various factors (NaOH concentration, solid content and pre-treatment time) that affect the pre-treatment process were investigated and evaluated based on the reducing sugar yield of the subsequent enzymatic hydrolysis. The...

Role of G-Substrate in the NO/cGMP/PKG Signal Transduction Pathway for Photic Entrainment of the Hamster Circadian Clock.

ASN neuro

Plano SA, Alessandro MS, Trebucq LL, Endo S, Golombek DA, Chiesa JJ.
PMID: 33430619
ASN Neuro. 2021 Jan-Dec;13:1759091420984920. doi: 10.1177/1759091420984920.

The mammalian circadian clock at the hypothalamic suprachiasmatic nuclei (SCN) entrains biological rhythms to the 24-h cyclic environment, by encoding light-dark transitions in SCN neurons. Light pulses induce phase shifts in the clock and in circadian rhythms; photic signaling...

A novel film-pore-surface diffusion model to explain the enhanced enzyme adsorption of corn stover pretreated by ultrafine grinding.

Biotechnology for biofuels
