The present disclosure relates to waxy maize starches having desirably high process stability, and to methods relating to them, including methods for making and using them. One aspect of the disclosure is a waxy maize starch having an amyiopectin content in the range of 90-100%; wherein the amyiopectin fraction of the waxy maize starch has at least 28.0% DP3-12 branches; and no more than 53.0% DP 13-24 branches, no more than 16.0% DP 25-36 branches. Such waxy maize starches can be advantaged over conventional waxy maize starches in that they can have increased process stability, especially with respect to freeze-thaw stability. Methods of making the starch materials, using exo-hydrolyzing enzymes and methods of using the starch materials in food products are also described.

An enzymatically produced soluble α-glucan fiber composition is provided suitable for use as a digestion resistant fiber in food and feed applications. The soluble α-glucan fiber composition can be blended with one or more additional food ingredients to produce fiber-containing compositions. Methods for the production and use of compositions comprising the soluble α-glucan fiber are also provided.

Enzymatic synthesis of soluble glucan fiber

An enzymatically produced α-glucan oligomer/polymer compositions is provided. The enzymatically produced α-glucan oligomer/polymers can be derivatized into α-glucan ether compounds. The α-glucan oligomers/polymers and the corresponding α-glucan ethers are cellulose and/or protease resistant, making them suitable for use in fabric care and laundry care applications. Methods for the production and use of the present compositions are also provided.

Glucan fiber compositions for use in laundry care and fabric care

An enzymatically produced &#x3b1;-glucan oligomer/polymer compositions is provided. The enzymatically produced &#x3b1;-glucan oligomer/polymers can be derivatized into &#x3b1;-glucan ether compounds. The &#x3b1;-glucan oligomers/polymers and the corresponding &#x3b1;-glucan ethers are cellulose and/or protease resistant, making them suitable for use in fabric care and laundry care applications. Methods for the production and use of the present compositions are also provided.

An enzymatically produced soluble &#x3b1;-glucan fiber composition is provided suitable for use as a digestion resistant fiber in food and feed applications. The soluble &#x3b1;-glucan fiber composition can be blended with one or more additional food ingredients to produce fiber-containing compositions. Methods for the production and use of compositions comprising the soluble &#x3b1;-glucan fiber are also provided.

Recombinant bacteria capable of metabolizing sucrose are described. The recombinant bacteria comprise in their genome or on at least one recombinant construct, a novel nucleotide sequence encoding a polypeptide having sucrose transporter activity and a nucleotide sequence encoding a polypeptide having sucrose hydrolase activity. These nucleotide sequences are each operably linked to the same or a different promoter. Recombinant bacteria capable of metabolizing sucrose to produce glycerol and/or glycerol-derived products such as 1,3-propanediol and 3-hydroxypropionic acid are also described.
