This paper deals with propionic acid extraction by tri-n-butylphosphate (TBP), a phosphorusbonded, oxygen-containing extractant dissolved in inert diluent (decane and kerosene) and a modifier (1decanol) at different temperature in the range of 298 K to 333 K. Active diluents (1-decanol) that enhance the extracting power of amines and phosphorus-bonded, oxygen-containing extractants are more fav...

The accumulation of volatile fatty acids (VFAs) through the anaerobic fermentation organic waste, such as strawberry extrudate, is proposed for this work. A hydrothermal treatment was carried out, and it to break complex matrix extrudate favour hydrolysis stage digestion process. production from treated untreated evaluated by adjusting pH 5 9. After an increase in solubilisation matter, sugars ...

Production of propionic acid by fermentation of propionibacteria has gained increasing attention in the past few years. However, biomanufacturing of propionic acid cannot compete with the current oxo-petrochemical synthesis process due to its well-established infrastructure, low oil prices and the high downstream purification costs of microbial production. Strain improvement to increase propion...

The earth’s climate is changing because of the increase in greenhouse gas (GHG) concentration, to which livestock a major contributor. Methane produced from cattle can be reduced by using high quality forages. This study compared GHG M. oleifera an artificial ruminant system with two pasture species, ryegrass and white clover. total production were measured vitro batch culture system. A prelimi...

Polyhydroxyalkanoates (PHAs) can be produced by microorganisms and are a biodegradable alternative to fossil-fuel based plastics. Currently, the focus is on reducing production costs by exploring alternative substrates for PHAs production, and on producing copolymers which are less brittle than monomers. Accordingly, this study used a substrate consisting of wastewater from waste-glycerol ferme...

This study was conducted to assess the effects of microbial and chemical combo additives on nutritive values, fermentation indices and aerobic stability of whole crop barley silage. Barley forage (Youngyang) was harvested at about 30% dry matter (DM) by treatments, chopped to 5 cm length and treated with distilled water only (CON), Lactobacillus plantarum (INO), propionic acid (PRO) or an equal...

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 Petroleum-based materials and chemical have been replaced by biological-based materials and chemicals with environmental advantages such as sustainability and biodegradability [2, 3].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),...

Background: Mulberry fruit is a source of phenolic compounds and has biological properties. This study aimed to assess the effects isomaltooligosaccharide (IMO) added mulberry juice on prebiotic activity gut fermentation properties.Objectives: The produce supplemented with IMO, which might generate short chain fatty acids (SCFA), examine after fecal fermentation.Materials methods: Functional ju...
