    摘要： The present invention relates to a DNA sequence, which codes for endomannanase produced by fungi of the genus Trichoderma and transferred into a yeast or fungus strain induces that strain to produce endomannanase, as well as to a method for isolating genes coding for endomannanases. The invention also relates to vectors, yeast strains and fungal strains containing the DNA sequence. Furthermore, the invention provides an enzyme product containing at least one endomannanase, which contains at least one of the following endomannanases produced by fungi of the Trichoderma genus: an enzyme having mannanase activity and an isoelectric point (pI) of about 3.8, an enzyme having mannanase activity and a pI of about 4.1, an enzyme having mannanase activity and a pI of about 4.5, an enzyme having mannanase activity and a pI of about 5.4 and an enzyme having mannanase activity and a pI of about 6.5, the isoelectric points being determined by isoelectric focusing. The endomannanase enzyme and enzyme products according to the invention can be used for hydrolyzation of mannopolymers, in particular in connection with bleaching of lignocellulosic pulps.

    摘要： Soil microorganisms are obtained that produce a hemicellulase which is particularly useful in increasing the available energy content of hemicellulosic foodstuffs. These microorganisms can be cultured per se or can be used as sources of genetic information with which to engineer other microorganisms to produce the enzyme. Thus, commercially useful quantities of native or recombinant hemicellulase can be produced with cultures consisting essentially of microorganisms that produce the enzyme. The hemicellulase can then be employed in a feed composition containing complex carbohydrates which the enzyme degrades, enhancing the nutritional value of the composition.
