The present invention is related to an improved production of bacterial proteins in filamentous fungus, e.g. inand. The improvement is achieved by constructing expression vectors, which comprise the bacterial protein encoding DNA sequences fused in frame with a DNA sequence encoding a filamentous fungus secretable protein or one or more functional domains of said protein. Filamentous fungus hosts transformed with such expression vectors secrete the desired proteins or enzymes, especially xylanases or cellulases originating from bacteria or more preferably from actinornycetes into the culture medium of the host. The desired proteins or enzymes can be used directly from the culture medium after separation of host cells or recovered and treated using down-stream processes, which are appropriate for the respective application. Xylanases or cellulases from actinomycetes produced using the above expression vectors are most suitable for treating plant derived materials e.g. in pulp and paper industries.

Production and secretion of proteins of bacterial origin in filamentous fungi

The production of thermostable xylanses having bacterial origin is described. These compositions are useful for modifying plant biomass and for enzyme-aided bleaching of wood pulp.

Sequences of Xylanase and Xylanase expression vectors

DNA encoding novel xylanases, vectors containing such DNA, hosts transformed with such DNA, enzyme preparations, and the use of such preparations are described.

Xylanases, genes encoding them, and uses thereof

Sequences of xylanase and xylanase expression vectors

Enzyme compositions containing thermostabile xylanases of Chaetomium thermophilum, purified enzyme preparations of such xylanases, and the use of such compositions and preparations in the bleaching of plant pulp and in feed and baking applications are described.

Xylanases and uses thereof

A degradation product of a polysaccharide derivative comprising a mixture of oligomers of the polysaccharide derivative, the majority of said oligomers having a molecular weight such that the oligomer conforms to a rod-like configuration.

Degraded polysaccharide derivatives

Degraded polysaccharide derivatives and foodstuffs containing same

Foodstuffs containing novel degraded cellulose derivatives
