Consolidated Bioprocessing in Brewing and Distilling
Authors: Burelle, Ian; Orsat, Val
Description: Although equipment may have changed, the process of brewing beer has remained relatively the same for centuries. Improvements in energy and water efficiency have occurred, but little of the available modern food processing technologies have grown into regular usage. Flash pasteurization, filter presses, and many more process operations cannot be easily employed due to the simple fact that the brewing wort is required to sit on the grain bed for extended periods of time for the effective enzymatic conversion of starch to fermentable sugars to occur.
Avoiding this step could allow for modern equipment to be introduced into breweries, with strong potential to develop new manufacturing processes and opportunity to develop entirely new product lines. This can be achieved by having necessary yeasts produce extra-cellular enzymes to convert the solubilized starch into sugar which they can subsequently ferment to ethanol in a single step. Consolidation of these two steps occurs rather frequently in biofuel production and several yeasts capable of doing so are currently available. This potential is within arm
