  • Patent number: 8178759
    Abstract: Barley with reduced SSII activity has a starch structure with reduced amylopectin content and a consequent high relative amylose content. Additionally the grain can have a relatively high ? glucan content. The structure of the starch may also be altered in a number of ways which can be characterized by having a low gelatinzation temperature but with reduced swelling. The viscosity of gelatinized starch of the starch is also reduced. There is a chain length distribution of the amylopectin content and a low crystallinity of the starch. The starch is also characterized by having high levels of lipid associated starch exhibiting very high levels of V form starch crystallinity. The dietary fiber content of the starch is high. This has desirable dietary and food processing characteristics.

One aspect of the invention relates to a two-stage pretreatment process comprising a relatively low severity steam treatment, a controlled pH pretreatment, or autohydrolysis, followed by hydrolysis with dilute acid or hot water at a relatively low temperature. In certain embodiments, the methods increase hemicellulose sugar yields, substrate digestibility, and suitability for fermentation as compared to steam explosion or acid hydrolysis alone. The two-stage pretreatment processes also employ few chemicals, minimizing the costs associated with pretreatment of lignocellulosic biomass. Moreover, the two-stage pretreatment process may expand the range of suitable feedstocks for bioethanol production.

    Abstract: In one embodiment the instant invention generally pertains to a method for producing glucose for fermentation. The method comprises first treating a biomass with acid and heat under conditions sufficient to produce a composition mixture comprising cellulose suitable for enzymatic hydrolysis. Next, at least a portion of the cellulose of step (a) is enzymatically hydrolyzed under conditions sufficient to form a composition comprising glucose. The glucose is then fermented. Advantageously, one or more reaction conditions are more efficient because they are selected by first measuring an initial hydrolysis rate of said biomass and then selecting one or more appropriate reaction conditions based upon said initial hydrolysis rate.

  • Publication number: 20110201059
    Abstract: Provided herein are methods for producing fermentable sugar obtained from a plant tissue. The methods include providing transgenic plant material comprising one or more locked carbohydrates and contacting plant material with an enzyme capable of converting the locked carbohydrate into a fermentable sugar. The methods are useful for providing sugar or sugar pre-cursors for several industrial purposes including ethanol production. The invention also encompasses plants and plant parts that produce a lock enzyme to yield a locked carbohydrate, with the consequence of accumulating the locked carbohydrate in the plant. The invention also encompasses providing a key enzyme able to convert locked carbohydrates to fermentable sugars. Key enzymes can be provided by transgenic plants or plant parts, transgenic microbes, transgenic yeast, microbes or yeast.
