Protein suspension from brewer's grains, method and apparatus for obtaining same
The group of inventions relates to the food industry, and more particularly to a method and device for transforming brewer's spent grain (BSG). The invention makes it possible to increase the level of recovery of edible fractions from BSG to 90-95%, and to increase the amount of protein in an edible suspension to not less than 50 wt % dry solids. The underlying principle of the invention is a technique for preparing BSG for nutrient extraction and extracting said nutrients by mechanical processing on a proposed industrial processing line. The essence of the claimed method lies in loosening BSG on a vibratory sieve, grinding the BSG in a colloid mill with the addition of water or centrate in a ratio of from 0.5:1 to 1:1 relative to BSG to produce a paste-like homogeneous mass of BSG, and then processing said mass in a screw extractor for further grinding and separation into two fractions: an edible suspension having a 90-95% moisture content and containing all of the nutrients of BSG, including protein substances; and ground BSG husks having a 60-75% moisture content, suitable for subsequent industrial use. The edible suspension is then mechanically filtered to remove ground husk residue, and the suspension is pumped into a storage tank.

POPTAG PEPTIDE AND USES THEREOF
Proteins and fusion proteins for forming merbraneless droplets in cells are provided. Described herein, is the development of a protein, named PopTag, that drives phase separation when it is part of a chimeric fusion protein. PopTag is engineered from the PopZ protein, found in a-proteobacteria (including Caulobacter crescentus). Despite PopZ being exclusively found in this clade of bacteria, the PopTag can drive protein phase separation in other prokaryotes (e.g., E. coli) and eukaryotes (e.g., human cells).
