Abstract:
1. A method of improving fermentation, including the steps of: heating stillage to a temperature of 200° F. to 350° F. and holding the stillage at the temperature for 3 to 180 minutes and at a pressure at or above the saturation pressure of the stillage resulting in hydrothermally treated stillage including oil, a high protein solids fraction, and a stickwater fraction; removing from the hydrothermally treated stillage some of a composition of dissolved solids by a mechanism chosen from the group consisting of membranes, biological remediation, electro-dialysis, ion exchange, distillation, solvent extraction, and precipitation; after removal of some of a composition of dissolved solids, preparing a media that includes all or a portion of the hydrothermally treated stillage; and using the media in a process chosen from the group consisting of fermentation and biomass production.
