摘要:
A four-roller type sizing mill apparatus for forming round steel rods, comprises two four-roller mills each having two pair of facing rollers. One pair of facing rollers is arranged in rolling direction perpendicular to the rolling direction of the other pair of rollers. The two four-roller mills are arranged in line, with the rolling direction of one of the two four-roller mills being shifted by 45.degree. from the rolling direction of the other four-roller mill. The two pair of rollers of a first four-roller mill positioned closer to the rolling material inlet are separated from each other by a distance which is greater than zero and not greater than five times the projected contact length of one of the pair of rollers positioned closer to the rolling material inlet. The distance is measured between a first standard straight line which passes through the centers of one of the pair of rollers and lies on a plane parallel to the side surfaces of the same pair of rollers and a second standard straight line obtained by projecting the axes of the other pair of rollers onto the above-mentioned plane.

This invention relates to a novel microorganism that efficiently produces a dodecahydro-3a,6,6,9a-tetramethylnaphtho[2,1-b]furan intermediate using sclareol as a substrate. As a result of concentrated studies, a plurality of novel microorganisms having properties of interest that are not classified as conventional microorganisms were isolated and identified. The novel microorganism of the present invention belongs to Ascomycetes and has the ability of producing a dodecahydro-3a,6,6,9a-tetramethylnaphtho[2,1-b]furan intermediate using sclareol as a substrate. Such microorganism of Ascomycetes represents a new finding and it can be effective for producing dodecahydro-3a,6,6,9a-tetramethylnaphtho[2,1-b]furan and an intermediate thereof.

The invention relates to a mutant α-amylase obtained by making replacement or deletion of at least one of amino acid residues such as the 167th Gln, 169th Tyr and 178th Ala in the amino acid sequence set forth in SEQ ID NO:1 in an α-amylase having said amino acid sequence, or an α-amylase having a homology of at least 70% to said amino acid sequence, a gene encoding the mutant α-amylase, a vector, transformed cells, a process for producing a mutant α-amylase, comprising culturing the transformed cells, and a detergent composition comprising the mutant α-amylase. The mutant α-amylase of the invention has excellent properties of high resistance to chelating agents, high specific activity in an alkaline region and excellent stability to heat, and is hence useful for detergents for automatic dish washer, laundry detergents and the like.

摘要:
A proteinase-resistant cellulase, a microorganism producing the same, and a process for producing such a proteinase-resistant cellulase is disclosed. The cellulase can be used as an additive to detergent compositions for washing clothes containing a proteinase, without immobilization or stabilization by chemical modification. The proteinase-resistant cellulase can be produced by a novel microorganism, Aspergillus niger KSM-24 [deposited with Fermentation Research Institute, Agency of Industrial Science and Technology (FERM BP-3359)].

摘要:
Liquefying alkaline amylases, each having residual activity not less than 70% when treated at pH 10 and 45° C. for 30 minutes in the presence of 1 to 100 mM of EDTA or EGTA, are described. Also described are detergents comprising these amylases. In comparison with conventional amylases for detergents, the liquefying alkaline amylases of this invention have a high chelating-agent resisting performance.
