Characterization of spoilage yeasts isolated from fermented vegetables and inhibition by lactic, acetic and propionic acids
. Food Microbiol 2002;19:363-73.
In this paper, a new Cu(II) complex with bi-[N-(propionic acid
)] terephthalal diacythydrazon (H4L) was synthesized, and the antibacterial activities of the complex against coliform and wheat rust were investigated, respectivly.
Significant interactions between diet and supplement were observed for formic acid, propionic acid
, isobutyric acid, valeric acid, and lactic acid concentrations.
The components of ethanol and VFAs (acetic acid, propionic acid
, and butyric acid from the liquid phase of the reaction system) were analyzed through gas chromatography (AAC GC-112, China).
Acetic acid was significantly (P<0.05) low in G2 and G3, while propionic acid
and yeast was significantly (P<0.05) low in LAB2.
One possibility is its use in the propionic fermentation, wherein lactose and lactate whey can be converted to propionic acid
by propionic bacteria (Kosmider, Drozdzynska, Blaszka, Leja, & Czaczyk, 2010).
Another operational variables studied in case of delignification of kikar wood by formic and propionic acid
were percentages of acid and HCl as catalyst and S/L ratios.
The acid is different from the chelating agent and is selected from the group consisting of glycolic acid, citric acid, lactic acid, formic acid, acetic acid, propionic acid
, butyric acid, valeric acid, caproic acid, gluconic acid, itaconic acid, trichloroacetic acid, benzoic acid, urea hydrochloride, and combinations thereof.
Aqueous polyurethane dispersions is a polymer prepared from toluene di-isocyanate, polytetramethylene glycol, and 1,4-butanediol, with different weight percent of dimethylol propionic acid
(DMPA) as anionic center.
Stool samples were analysed for short-chain fatty acids (acetic acid, propionic acid
, butyric acid, isobutyric acid, valeric acid, and isovaleric acid) by gas chromatography.
Furthermore, it is used as precursor of several other products, such as propylene oxide, acetaldehyde, acrylic acid, propionic acid
, 2,3-pentanedione, ethyl lactate, and polylactic acid ; the latter is used for production of biodegradable polymers with medical applications.
Bacterial treatments produced a significant effect on water soluble carbohydrate and propionic acid
And HNK's antidepressant effect is not related to NMDA receptors, but is instead tied to activation of alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid
This test reveals markedly elevated methylmalonic acid and elevated methylcitrate, propionic acid
, and 3-hydroxypropionic acid in patients with MMA.
