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...
متن کاملYeast responses to stresses associated with industrial brewery handling.
During brewery handling, production strains of yeast must respond to fluctuations in dissolved oxygen concentration, pH, osmolarity, ethanol concentration, nutrient supply and temperature. Fermentation performance of brewing yeast strains is dependent on their ability to adapt to these changes, particularly during batch brewery fermentation which involves the recycling (repitching) of a single ...
متن کاملBiological Pretreatment of a Beverage Waste Using Yeast Isolated from the Factory Sludge (RESEARCH NOTE)
The beverage industry has been a heavy producer of organic pollution. The major contaminants found in waste are biodegradable organic compounds, volatile organic compounds, toxic metals, and recalcitrant xenobiotics, suspend solids, nutrients (Nitrogen and Phosphor) Microbial pathogens and parasites. Activated sludge flocs contain a wide range of microorganisms such as bacteria, Fungi, yeast, v...
متن کاملPowering the porter brewery.
Before canals and railways developed as a major transport network, it was seldom profitable to transport beer inland over more than a few miles. In country towns and villages, therefore, beer would be brewed either by a small 'common' brewery that supplied a handful of pubs and private customers, or in an even smaller brew-house attached to the pub itself. Many families also brewed their own be...
متن کاملFractionation 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...
