摘要:
A process for integrated utilization of the energy and material contents of hydrolysates and solids obtained in the enzymatic hydrolysis of renewable raw materials, in which the resulting hydrolysis solution is used as a carbon source in fermentations and the unhydrolysed solids are sent to biogas production.
摘要:
The present invention relates to a cell, which has been genetically modified relative to its wild type, so that in comparison with its wild type it is able to produce more ω-aminocarboxylic acids, more ω-aminocarboxylic acid esters or more lactams derived from ω-aminocarboxylic acids, starting from carboxylic acids or carboxylic acid esters. Furthermore, the present invention relates to a method for the production of a genetically modified cell, the cells obtainable by this method, a method for the production of ω-aminocarboxylic acids, of ω-aminocarboxylic acid esters or of lactams derived from ω-aminocarboxylic acids, the ω-aminocarboxylic acids, ω-aminocarboxylic acid esters or lactams derived from ω-aminocarboxylic acids obtainable by this method, a method for the production of polyamides based on ω-aminocarboxylic acids or based on lactams and the polyamides obtainable by this method.
摘要:
A sugar-containing hydrolyzate is produced from a lignocellulose-containing material by a) pretreating the lignocellulose-containing material with a chemical compound selected from sulphuric acid, alkali, peroxodisulphates, potassium peroxide, potassium hydroxide, and mixtures thereof, in the presence of water, thereby obtaining an aqueous phase, and b) after removing of the aqueous phase and washing the resulting product, treating said product with an enzyme suitable for hydrolysis in the presence of water, thereby obtaining a hydrolyzate, the hydrolyzate being suitable as a carbon source for fermentation.
