This invention relates to a method for decreasing the foam formation during cultivation of a microorganism and to a method for producing an enhanced amount of a product of interest. The method comprises that the microorganism is modified in such a way that the microorganism does not produce an essential amount of at least one of the proteins, polypeptides or peptides associated with foam formation during cultivation of the unmodified microorganism. In particular the method comprises that the microorganism is modified not to produce an essential amount of amphipathic or hydrophobic proteins, polypeptides or peptides.

Method for decreasing the foam formation during cultivation of a microorganism

The present invention concerns a method for enzymatic treatment of lignocellulosic materials which contain xylan-polymers, such as cellulose kraft pulps. According to a method of the present kind, at least a part of the hexenuronic acid groups present in the material is selectively removed in order to remove metal ions from the pulp, to change the surface charge thereof, to improve the brightness stability of the pulp and to render the material more suitable for enzymatic treatment.

Method of modifying a xylan-containing carbohydrate substrate having hexenuronic acid groups attached to the xylan

The present invention is directed to novel xylanases (referred to as XYL-IV) and to nucleic acid molecules encoding those xylanases. Also provided herein are vectors and host cells including those nucleic acid sequences, antibodies which bind to the xylanases of the present invention, methods for producing the xylanases of the present invention, and methods employing the xylanases of the present invention.
