Abstract: The present invention is related to an improved production of bacterial proteins in filamentous fungus, e.g. in Tfichodenna and Aspergillus. 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.

Abstract: Genes encoding novel cellulases, and a gene encoding a protein that facilitates the action of such novel cellulases, the novel cellulases and a protein that facilitates the action of such cellulases, and enzyme preparations containing such proteins are described The native hosts and the culture medium of said hosts containing said novel cellulases are also disclosed. These proteins are especially useful in the textile and detergent industry and in pulp and paper industry.

Abstract: A method is described for the identification and cloning of promoters that express under a defined environmental condition, such as growth in glucose medium. Using this method, five Trichodermal promoters capable of the high expression of operably linked coding sequences are identified, one of which is the promoter for T. reesei tef1. Also provided are altered cbh1 promoters, altered so that glucose no longer represses expression from such promoter. The invention further provides vectors and hosts that utilize such promoters, and unique fungal enzyme compositions from such hosts.

Abstract: The isolation and cloning of Actinomadura spp. xylanases having a molecular weight of 35 kDa and 50 kDa are described. These xylanases are thermostable and useful in biobleaching of wood pulp.

Abstract: 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.

Abstract: The present invention is directed to a new cellulase composition for treating and finishing cellulose-containing textiles. The improved properties of the cellulase composition are based on an elevated content of EGII endoglucanase type component in an otherwise complete cellulase composition. When the composition with elevated EGII contents is used improved color properties, increased lightness, improved visual appearance and reduced pilling tendencies are achieved. The strength properties of the textile materials are essentially unchanged as compared to previously used cellulase compositions.

Abstract: The present invention is directed to a new cellulase composition for finishing of cellulose-containing textiles, especially cotton. The improved properties of the cellulase composition are based on an elevated content of CBHII cellobiohydrolase type component in an otherwise normal background cellulase composition. When the composition with elevated CBHII contents is used improved color properties, increased lightness, improved visual appearance and reduced pilling tendencies are achieved. The strength properties of the textile materials are essentially unchanged as compared to previously used cellulase compositions.

Abstract: 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.

Abstract: The present invention provides a recombinant combination strain which is capable of over-expressing at least two different genes under two separate promoters in filamentous fungi. The genes encode phytase and pH 2.5 acid phosphatase. Mixtures containing desired ratios of the two enzymes are prepared by recombinant DNA techniques. The enzyme mixtures show a cooperative effect in the degradation of phytic acid and its salts. The preferred ratios of the two enzymes are from about 3:1 to about 16:1.
