摘要:
The invention relates to a phytase derived from Citrobacter braakii and related phytases. The phytases belong to the acid histidine phosphatase family, are acid-stable, of an excellent performance in animal feed, of a high specificity towards the substrate phytate, and expectedly of a high specific activity. The invention also relates to the corresponding DNA, the recombinant and wild-type production of the phytases, as well as the use thereof.

摘要:
A method for high throughput micro-purification of a library of tag-free biological compounds is claimed wherein a population of discrete liquid samples comprising the library of tag-free biological compounds is contacted with a solid chromatographic material comprising a functional group selected from ion exchange materials, hydrophobic materials, affinity materials and hydrophobic charge induction materials so as to retain the tag-free biological compounds of the library, isolating the chromatographic material retaining the biological compounds, releasing the biological compounds of the library from the solid chromatographic material and collecting the released biological compounds of the library to produce a population of samples comprising the isolated biological compound.

摘要:
The invention relates to a process of producing a fermentation product, such as ethanol, from starch-containing material, including i) subjecting starch-containing material to an alpha-amylase, ii) subjecting the material obtained in step i) to an alpha-glucosidase and/or a maltose-generating enzyme, and iii) fermenting the material in the presence of a fermenting organism, such as yeast. Alternatively the invention relates to a process of producing a fermentation product from starch-containing material, preferably granular starch, which process comprises: a) subjecting starch-containing material to an alpha-glucosidase and optionally a glucose-generating and/or maltose-generating enzyme, and b) fermenting the material in the presence of a fermenting organism.
