Abstract: Embodiments of the present disclosure relate to a process for producing isoprene from a starch substrate by saccharification and/or fermentation. The saccharification is effectively catalyzed by a glucoamylase at a pH in the range of 5.0 to 8.0. At a pH of 6.0 or above, the glucoamylase possesses at least 50% activity relative to its maximum activity. The saccharification and fermentation may be performed as a simultaneous saccharification and fermentation (SSF) process.

Abstract: Provided herein are compositions and methods related to the direct conversion of the starch in a ground or fractionated grain into a fermentable sugar feedstock capable of serving as a carbon source for the industrial production of one or more products by a fermenting organism, such as isoprene, isoprenoid precursor molecules, and/or isoprenoids. Such conversions may be performed at temperatures at or below the initial gelatinization temperature of the starch present in the grain and may utilize one or more isolatable endogenous enzymes present in certain unrefined grains.

Abstract: The present invention relates to a process for producing a rice protein concentrate from a rice substrate comprising, enzymatically hydrolyzing a rice substrate with an enzyme having granular starch hydrolyzing (GSH) activity and a second starch hydrolyzing enzyme at a temperature at or below 72° C. and at a pH of about 3.0 to 6.5 to obtain a solubilized starch fraction and a residue fraction which includes insoluble protein, and separating the solubilized starch fraction from the residue to obtain a rice protein concentrate. The rice protein concentrate may be used in animal feed and human food formulations.

Abstract: Variants of a Pseudomonas saccharophila G4-forming amylase (PS4) advantageously can catalyze high temperature saccharification to produce maltotetraose syrup from a starch liquefact or granular starch, e.g., derived from cornstarch. The PS4 variants are useful in a process of saccharification of starch that advantageously produces significant amounts of maltotetraose, which can be used downstream in a process of producing a maltotetraose syrup. In one embodiment, a thermostable PS4 variant is provided that can produce about 40% to about 60% by weight maltotetraose, based on total saccharide content.
