Abstract: A structural board includes a pair of intermediate members having plural projections. The intermediate members are positioned in parallel, and the projections are in contact with each other between the intermediate members. At least one of the intermediate members are light permeable. An illuminator is provided between the intermediate members.

Abstract: A floor sheet assembly has an intermediate member and a pair of sheet members. The intermediate member includes at least a thin panel, on which a plurality of hollow projections is formed. The pair of sheet members sandwiches the intermediate member. The intermediate member and the pair of sheet members form a honeycomb structure.

Abstract: An expressing system which enables a large amount of production of a protein in Humicola, in particular, Humicola insolens, and particularly host-vector systems and a process for producing a protein using the systems, wherein an expression vector comprising the regulator sequences, i.e., the promoter, the signal sequence, and the terminator, of the cellulase NCE1 gene or NCE2 gene derived from Humicola insolens is constructed and used. The expression vector enables highly efficient production of cellulase NCE4, for example, in Humicola insolens at a rate as high as about 4.5 g or more per one liter of culture.

Abstract: A high-yield production system for proteins and peptides has been established, and especially a high-yield production system for cellulase in Trichoderma viride and similar filamentous fungi. The cellulase cbh1 gene regulator sequence derived from Trichoderma viride gives high expression of target proteins. The regulator sequence can therefore be used for high-yield expression of target proteins, especially cellulase. In particular, 15 g/L of an endoglucanase derived from Humicola insolens was successfully produced with this regulator sequence.

Abstract: A highly active cellulase suitable for use in a removal of nap of cellulose-containing fibers, a process for reducing cellulose-containing fibers and a process for decoloring denim-dyed cellulose-containing fibers, and its gene are provided. A novel cellulase NCE4 isolated from Humicola insolens is a highly active cellulase, and can be used for various treatments of cellulose-containing fibers.

Abstract: The object of the present invention is to analyze the amino acid sequence of the protein constituting the cellulase system, to clone the gene coding for the components of the cellulase system, and to establish a technique of inserting a clonal gene into the above strain thereby to produce cellulase having enhanced avicellase activity. The present invention relates to a protein having a part or the whole of the amino acid sequence depicted in the sequence listing under SEQ ID NO:1 and possessing cellulase activity, a DNA coding for the protein, an expression vector containing the DNA, a microorganism as transformed by the expression vector, and a process for producing a protein having enhanced cellulase activity by using the microorganism.

Abstract: A method for transforming strain PF1022, which produces a cyclic depsipeptide (substance PF1022) and belongs to the order Agonomycetales of the class Hyphomycetes has been established by using a plasmid constructed with a promoter, a terminator, a marker gene and a target gene. When the strain PF1022 was transformed by this method, a gene encoding an enzyme, which is the target gene, was transduced into the host. As a result, the utilization of nutrients by the strain PF1022 was improved and, further, its cyclic depsipeptide productivity was also improved.
