In 2016,De Leon-Gonzalez, Grecia; Gonzalez-Valdez, Jose; Mayolo-Deloisa, Karla; Rito-Palomares, Marco published 《Intensified fractionation of brewery yeast waste for the recovery of invertase using aqueous two-phase systems》.Biotechnology and Applied Biochemistry published the findings.Safety of Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate The information in the text is summarized as follows:
The potential recovery of high-value products from brewery yeast waste confers value to this industrial residue. Aqueous two-phase systems (ATPS) have demonstrated to be an attractive alternative for the primary recovery of biol. products and are therefore suitable for the recovery of invertase from this residue. Sixteen different polyethylene glycol (PEG)-potassium phosphate ATPS were tested to evaluate the effects of PEG mol. weight (MW) and tie-line length (TLL) upon the partition behavior of invertase. Concentrations of crude extract from brewery yeast waste were then varied in the systems that presented the best behaviors to intensify the potential recovery of the enzyme. Results show that the use of a PEG MW 400 g mol-1 system with a TLL of 45.0% (weight/weight) resulted in an invertase bottom phase recovery with a purification factor of 29.5 and a recovery yield of up to 66.2% after scaling the system to a total weight of 15.0 g. This represents 15.1 mg of invertase per mL of processed bottom phase. With these results, a single-stage ATPS process for the recovery of invertase is proposed. In the part of experimental materials, we found many familiar compounds, such as Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate(cas: 6381-59-5Safety of Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate)
Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate(cas: 6381-59-5) is a ferroelectric crystal with a high piezoelectric effect and electromechanical coupling coefficient. Safety of Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate As a Biuret reagent, it is used to measure the protein concentration. Furthermore, it is used as laxative and is also used in food industry.
