摘要:
The inventors have developed a method of modifying the amino add sequence of a CGTase to obtain variants. The variants may form linear oligosaccharides as an initial product by starch hydrolysis and a reduced amount of cyclodextrin and may be useful for anti-staling in baked products. The method is based on a comparison of three-dimensional (3D) structures of the CGTase with the structure of a maltogenic alpha-amylase where one or both models includes a substrate. The invention also provides novel CGTase variants.
摘要:
The inventors have developed a method of altering the amino acid sequence of a fungal alpha-amylase to obtain variants, and they have used the method to construct such variants. The variants may be useful for anti-staling in baked products. Accordingly, the invention provides a method of constructing fungal alpha-amylase variants based on a comparison of three-dimensional (3D) structures of the fungal alpha-amylase and a maltogenic alpha-amylase. One or both models includes a substrate. The invention also provides novel fungal alpha-amylase variants.
摘要:
The formation of acrylamide during heat treatment in the production of a food product is reduced by treating the raw material with an enzyme before the heat treatment. The enzyme is capable of reacting on asparagine as a substrate.
摘要:
A method is provided for identifying components of a mixture by labeling the individual components with fluorescent agents having different fluorescence lifetimes. The components are subsequently separated, fluorescent labels detected and their lifetimes measured. Based on the measured fluorescent lifetimes, the components of mixtures of small organic molecules, polymers, peptides, saccharides and nucleic acids can be identified.

摘要:
This invention provides methods and systems for injection of analytes into a separation channel for resolution and detection. Samples can be preconditioned and concentrated by isotachophoresis (ITP) before the injection is triggered by a detected voltage event. Separation of analytes from other sample constituents can be enhanced using skewing channel ITP.
摘要:
The formation of acrylamide during heat treatment in the production of a food product is reduced by treating the raw material with an enzyme before the heat treatment. The enzyme is capable of reacting on asparagine or glutamine (optionally substituted) as a substrate or is a laccase or a peroxidase.
摘要:
The addition of a lipoxygenase and a lipolytic enzyme active on polar lipids to a dough has a synergistic effect on the volume and/or crumb color of an edible product made by leavening and heating the dough, e.g. by baking or steaming.
摘要:
A system tracks ownership data for data resources coupled on a network. The system includes a data extractor for extracting data resource communication activity data from a plurality of network activity data sources, a database of organizational data resource ownership data, and a communication activity report generator for correlating extracted data resource communication activity data and organizational data resource ownership data so that ownership of communication activity may be tracked. The data extractor obtains network activity data from a variety of data sources such as firewalls, routers, servers, PBXs, softswitches, media gateways, SS7 signaling points, integrated access devices, and calling card imports. Network activity data about communication activity may be obtained directly from the data resources initiating the communication activity or from data sources that handle communication activity initiated by a data resource. The network activity data are then processed to extract data resource communication activity data. Organizational data resource ownership data includes data for identifying the data resources from which communication activity data are extracted and the organizational entities owning the data resources. Typically, these organizational entities include company data, division data, department data, and owner data. This data may then be linked to identify an owner as being associated with a particular department and division within a company. The communication activity report generator may be used to generate a response to a directory query or a history query. A response to a directory query identifies one or more data resources and the ownership data linked to that device. A response to a history query identifies for a particular time period, one or more data resources, the network activity initiated by those data resources and ownership data linked to those data resources.
