摘要:
The invention relates to a method for obtaining ethanol from a carbohydrate-containing raw substrate wherein the ethanol that is produced is separated during fermentation using a carrier gas. The invention further relates to the adsorption of the ethanol from the gas phase to an adsorber, the desorption of the ethanol during a subsequent process step, and to the further concentration of the ethanol.

摘要:
The invention concerns a process for the recovery of an organic moiecule from the overhead vapor phase of aqueous media by adsorbing onto an adsorbent, wherein no additional thermal energy for said vaporization is provided, and wherein the organic molecule is recovered afterwards by desorbing from the adsorber.
摘要:
The invention relates to a method for depolymerizing materials containing carbohydrates comprising the following steps: (a) treating a material containing carbohydrates with an inorganic catalyst in order to release defined monomeric or oligomeric building blocks from the material containing the carbohydrates; and (b) separating the defined monomeric or oligomeric building blocks produced in step (a) from the rest of the carbohydrate-containing material. Preferably, the inorganic catalyst used in step (a) comprises tectosilicates, phyilosilicates or hydrotalcites and more preferably zeolites or bentonites. The carbohydrate-containing material further comprises preferably LCB and the defined monomeric or oligomeric building blocks are preferably glucoses, xyloses, arabinoses and oligomers thereof. Other aspects of the invention refer to the use of solution promoters in combination with the inorganic catalyst.
摘要:
The present invention relates to polypeptides having xylanase activity and nucleic acid sequences encoding such polypeptides. The invention also relates to nucleic acid constructs, vectors, and host cells comprising the nucleic acid constructs as well as methods for producing and using the polypeptides. One specific application of the xylanase is the selective hydrolysis of pentose sugar components of hemicellulose-containing plant biomass. The nucleotide sequence may be used for the production of the xylanase or optimized mutants thereof.

The present invention relates to enzymes and processes. In particular, there is described an isolated polypeptide comprising the amino acid sequence corresponding to Citrobacter freundii phytase or a homologue, a modified form, a functional equivalent or an effective fragment thereof. There is also described a host cell transformed or transfected with a nucleic acid encoding a bacterial phytase enzyme or a modified form as well as the use of such a phytase or modified form in food or animal feed.
