This paper deals with the extraction and emulsifying properties of proteins from Chlorella vulgaris. Solubilisation of proteins has been achieved using high pressure cell disrupter under pH=7 or pH=12. The higher solubilisation yield (52±3%w/w) was obtained using a combination of alkaline conditions and mechanical treatments (2.7kbar). After solubilisation, proteins were recovered by two proced...

Abstract The establishment of sustainable bioeconomies requires the utilization new renewable biomaterials. One such material currently seen as a waste product is oat hulls. Oat hulls exhibit great potential for production dietary fibres due to their exceptionally large hemicellulose content (35%). Their recalcitrant structure however suitable pre-treatment method access and process hemicellulo...

alkaline crude enzymes from the viscera of the tunisian barbel (barbus callensis) were extracted and characterized. proteolytic crude extract from barbel viscera was active and stable in alkaline solution. the optimum ph and temperature were 11.0 and 55 °c, respectively, using casein as a substrate. the crude alkaline protease was extremely stable in the ph range of 5.0-12.0. zymography activit...

The effects of thermal-alkaline pretreatment on dewatered activated sludge (DAS) solubilisation and subsequent high-solid anaerobic digestion were studied by response surface methodology (RSM) from 105 to 135 °C and between 5 and 35 mg alkaline/g total solid (TS) DAS. Soluble chemical oxygen demand (SCOD), soluble carbohydrates, and protein concentrations were significantly enhanced in thermal-...

In the present contribution, the pre-structuring of binary mixtures of hydrotropes and H2O is linked to the solubilisation of poorly water miscible compounds. We have chosen a series of short-chain alcohols as hydrotropes and benzyl alcohol, limonene and a hydrophobic azo-dye (Disperse Red 13) as organic compounds to be dissolved. A very weak pre-structuring is found for ethanol/H2O and 2-propa...

Paramylon is a linear glucan produced by Euglena gracilis microalgae as water insoluble intracellular granules. Its macromolecular structure contains only β(1–3) linkages, resulting in stable triple helix conformation and high crystallinity. It soluble very few solvents such DMSO, harsh alkaline or acid solutions imidazolium ionic liquids. In this paper we prepared biosourced more ecofriendly l...

Microwave irradiation is a promising pre-treatment method for sludge stabilisation, but there are few studies focusing its effect on organic matter solubility and biodegradability of wastewater originated from the food industry. In our research, microwave was applied standalone in combination with alkaline treatment to enhance solubilisation biodegradation content meat industry municipal sludge...
