Brewing Method
A method of mashing comprising providing a grist comprising malt and adjunct; and contacting the grist with a pullulanase; an alpha amylase; and a maltogenic alpha amylase and/or a beta amylase to make a wort. An enzyme composition comprising a pullulanase; an alpha amylase; and a maltogenic alpha amylase and/or a beta amylase and the use of these enzymes in brewing is disclosed.
STABILIZED LIQUID ENZYME COMPOSITIONS FOR BREWING
The invention provides liquid enzyme compositions which are physically and microbially stable. The compositions are used, for example, in beer brewing processes.
FERMENTATION METHOD AND USES THEREOF
Various examples according to the present disclosure provide a fermentation method. The fermentation method includes producing at least about 10 g/L of a bioproduct and one or more heterologous polypeptides by fermenting a medium using an engineered microorganism. About 2 wt % to about 100 wt % of the one or more heterologous polypeptides are encapsulated intercellularly in the engineered microorganism. The method further includes isolating the engineered microorganism including the encapsulated one or more heterologous polypeptides. About 50 wt % to about 100 wt % of the one or more heterologous polypeptides retain functionality following isolation of the engineered microorganism.
Maltodextrin and process of making same
This specification discloses process for obtaining maltodextrin having DE between 17 and 19.9 and the maltodextrins obtained from the process. The disclosed maltodextrins can be provided as a powder or in shelf stable liquid form. The disclose maltodextrins have a polysaccharide profile similar to those observed for prior art maltodextrins, but make maltodextrin solutions having a high solids content, but reduced viscosity compared to prior art maltodextrins, on equivalent solids-in-solution basis. The process combines adds an alpha-amylase and a pullulanase enzyme to a polysaccharide mixture during a saccharification step. The disclosed maltodextrins make solutions at 50° C. and greater than 65% on a solids dry solids basis having a viscosity between 5,000 and 12,000 cP and having a water activity of less than 0.80.
Process of extracting oil from thin stillage
A process of recovering oil, comprising (a) converting a starch-containing material into dextrins with an alpha-amylase; (b) saccharifying the dextrins using a carbohydrate source generating enzyme to form a sugar; (c) fermenting the sugar in a fermentation medium into a fermentation product using a fermenting organism; (d) recovering the fermentation product to form a whole stillage; (e) separating the whole stillage into thin stillage and wet cake; (e′) optionally concentrating the thin stillage into syrup; (f) recovering oil from the thin stillage and/or optionally the syrup, wherein a protease and a phospholipase are present and/or added during steps (a) to (c). Use of a protease and a phospholipase for increasing oil recovery yields from thin stillage and/or syrup in a fermentation product production process.

Methods for analyzing lariat RNA
The present invention relates to compositions and methods useful for analyzing lariat RNA, which plays a role in the regulation of gene expression. A sample of RNA is specifically treated to remove linear mRNA and enrich for lariat RNA. The enriched lariat RNA sample may be analyzed further to identify introns, branch point sequences, alternative splicing patters, and gene transcription levels. The enriched lariat RNA sample may also be exploited as a detection or compound screening tool, as well as other uses.
