Brewery Waste Reuse for Protease Production by Lactic 
Acid Fermentation.

This study evaluated the use of three solid brewery wastes: brewer's spent grain, hot trub and residual brewer's yeast, as alternative media for the cultivation of lactic acid bacteria to evaluate their potential for proteolytic enzyme production. Initially, a mixture experimental design was used to evaluate the effect of each residue, as well as different mixtures (with the protein content set...

Teachers’ knowledge about epilepsy

Background and Purpose: Epilepsy is a disease frequently seen among school children. Teachers may be distressed by children having seizures as they do not receive specific training about this condition during their education. Moreover, teachers can feel overwhelmed if they do not know how to handle the situation. After cerebral apoplexy, epilepsy is the second most common central nervous system...

Fractionation and Purification of Bioactive Compounds Obtained from a Brewery Waste Stream

The brewery industry generates waste that could be used to yield a natural extract containing bioactive phenolic compounds. We compared two methods of purifying the crude extract-solid-phase extraction (SPE) and supercritical fluid extraction (SFE)--with the aim of improving the quality of the final extract for potential use as safe food additive, functional food ingredient, or nutraceutical. T...

Statistical Analysis and Optimization of Acid Dye Biosorption by Brewery Waste Biomass Using Response Surface Methodology

Biosorption of Acid Yellow (AY 17) and Acid Blue (AB 25) were investigated using a biomass obtained from brewery industrial waste spent brewery grains (SBG). A 2 full factorial response surface central composite design with seven replicates at the centre point and thus a total of 31 experiments were employed for experimental design and analysis of the results. The combined effect of time, pH, a...
