摘要:
The instant disclosure provides a genetically modified bacterial cell, i.e., modified Agrobacterium strain, which expresses a levansucrase and has reduced expression of endogenous CysK. As a result, the growth of the modified bacterial cell on medium or tissue culture with sucrose and deficient in cysteine is inhibited. The two-action growth control of the modified Agrobacterium strain can overcome the unmet issue of Agrobacterium overgrowth during plant transformation, and therefore increase the efficiency of plant transformation.

The present disclosure provides solutions to various challenges in health, including health challenges related to high consumption of carbohydrate and/or low consumption of soluble fiber. The present disclosure provides, among other things, bacteria engineered for expression of a fiber-synthesizing enzyme, e.g., for expression of the enzyme in the gut (e.g., in the intestine). In particular embodiments, the present disclosure provides bacteria engineered for expression of a fiber-synthesizing enzyme that consumes carbohydrate in the process of synthesizing fiber, e.g., in the gut. The present disclosure further includes formulations of isolated fiber-synthesizing enzymes for administration to subjects.
摘要:
Fruit juices, purees, and other food products are provided for the healthy-product market. A part of the available sugars in the fruit products is converted to non digestible polymers, thereby lowering the energetic content and simultaneously increasing the nutritional value by forming prebiotic components in the product stables in juices. Further provided is a method of manufacturing juices and purees, enabling to preserve all components but sugars naturally occurring in the fruit.

摘要:
The lactosucrose high-content powder according to the present invention is prepared by allowing an aqueous solution containing sucrose and lactose to act on a saccharidetransferring enzyme, removing concomitant saccharides in the resultant saccharide solution containing lactosucrose to obtain a solution having a high concentration of lactosucrose, i.e. lactosucrose content of 45 w/w % or more of the sugar composition, and spraydrying the resultant solution to obtain a powder having a high concentration of lactosucrose. The powder is incorporated in an orally- or parenterally-administrable product to obtain an orally- or parenterally-administrable product which exerts a selective growth-promoting-effect on a microorganism of the genus Bifidobacterium in vivo.
