Gas-liquid chromatography was performed on 233 positive blood cultures and findings were compared with culture results. Obligate anaerobic bacteria were recovered from 78 out of 79 blood cultures containing butyric or iso-valeric acids, or both; from 28 out of 69 blood cultures containing succinic acid; and from only one out of 41 blood cultures containing succinic but not butyric or iso-valeri...

Potato residue is a rich source of dietary fibre. Herein, the effects unmodified and enzymes (cellulase xylanase) modified potato fibres on distribution intestinal microbiotas production short-chain fatty acids (SCFAs) C57BL/6 mice were evaluated. Results showed that enzymatic modification increased soluble fibre content in residue. Administration these promoted acetic acid, n-butyric iso-butyr...

Iso-butyric acid as a new, simple, and expensive solvent/catalyst was successfully used for the chemoselective Fischer’s synthesis of indolenines derivatives 3a-r by one-pot condensation reaction of various phenylhydrazines 1a-e with the substituted acetophenones 2a-c at reflux conditions. In this protocol, all products 3a-r were obtained in high yields and short reaction time. The structures o...

Batch experiment was carried out in a simulated thermophilic aerobic digester to investigate the digestion process of one-stage autothermal thermophilic aerobic digester and to explore the sludge stabilization mechanism. Volatile solids removal was 38.4% at 408 h and 45.0% at 552 h. Chemical oxidation demand, total nitrogen, and ammonia nitrogen in supernatant increased rapidly up to 168 h, and...

This study was performed to investigate the effect of different levels of dietary crude protein (CP) on composition of odorous compounds and bacterial communities in pig manure. A total of 48 male pigs (average initial body weight 45 kg) fed diets containing three levels of dietary CP (20%, 17.5%, and 15%) and their slurry samples were collected from the pits under the floor every week for one ...

CO2 per year by 2030 [1]. Petroleum-based materials and chemical have been replaced by biological-based materials and chemicals with environmental advantages such as sustainability and biodegradability [2, 3]. One of these petroleum based-chemicals is the short chain carboxylic acids or volatile fatty acids (VFA). VFA are carboxylic acids with a carbon chain between 2 and 7 carbons [acetic (2),...
