The purpose of this investigation is to study the effect 1) leachate recirculation (LR) and dilution (LD), 2) increment waste ratio, 3) co-digestion using poultry as co-substrate for enhancing acidogenesis process organic municipal solid (OMSW), thereby increasing medium chain fatty acids (MCFAs) production. results experiment carried in a batch pilot reactor show that LR increases hydrolysis w...

Each cheese type has a unique flavor. A variety of compounds various concentrations and different chemical classes contribute to this In the present study, effect processing techniques (ultrasonication (US), high pressure (HPP), microwave (MW)) on flavors sensory properties milk was investigated. Samples treated untreated were analyzed for volatile (including aldehydes, ketones, alcohols, fatty...

Studied on the oxidation of oleic and octanoic acids to ketone bodies were carried out in homogenates and in mitochondrial fractions of livers taken from fed and fasted rats. Malonyl-CoA inhibited ketogenesis from the former but not from the latter substrate. The site of inhibition appeared to be the carnitine acyltransferase I reaction. The effect was specific and easily reversible. Inhibitory...

Fatty acids (FAs) are considered strategically important platform compounds that can be accessed by sustainable microbial approaches. Here we report the reprogramming of chain-length control of Saccharomyces cerevisiae fatty acid synthase (FAS). Aiming for short-chain FAs (SCFAs) producing baker's yeast, we perform a highly rational and minimally invasive protein engineering approach that leave...

We had extracted n-caproate from bioreactor broth. Here, we introduced in-line membrane electrolysis that utilized a pH gradient between two chambers to transfer the product into undissociated n-caproic acid without chemical addition. Due to the low maximum solubility of this acid, selective phase separation occurred, allowing simple product separation into an oily liquid containing ∼90% n-capr...

Meloidogyne incognita egg masses were immersed in different concentrations of six volaule fatty acids to bioassay their toxic effect on embryonic development and hatching. Exposure to a 250 ppm aqueous solution of volatile fatty, acids completely suppressed egg hatching within 48 hours. When exposed to a 125 ppm concentration hatching was reduced 75 % by acetic acid, 91% by propionic acid, 23% ...

Pyruvate has been shown to decrease the oxidation of palmitic acid by rat liver and kidney slices (l), but to have little influence on octanoate oxidation by liver slices (2, 3). Likewise, prior glucose administration decreased the rate of oxidation of palmitic acid by the rat in viva, but not that of octanoic acid (4). Glucose has also been reported to decrease the oxidation of serum lipides b...
