In an axial flow fan according to the present invention, a plurality of blades rotate about a rotation axis of the blades to convey a fluid. In the axial flow fan, the plurality of blades each have a leading edge at a leading side in a rotational direction, a trailing edge at a trailing side in the rotational direction, and an outer peripheral edge connecting the leading edge and the trailing edge. The leading edge of one of the plurality of blades and the trailing edge of another blade adjacent to the leading edge of the blade in the rotational direction are connected by a plate-shaped connection portion. The plurality of blades each have at least one plate-shaped reinforcement rib extending from a periphery of the rotation axis toward the outer peripheral edge of the blade.

A storage apparatus according to an aspect of the present invention is configured to perform a deduplication process on write data from a host. For the deduplication process, the storage apparatus calculates a feature value of write data, and records, in a management region, metadata that is a set of the feature value of the write data and information on a storage position of the write data. However, to prevent the amount of metadata stored in the management region from increasing, if write data meets a predetermined condition, the storage apparatus does not perform the deduplication process, and suppresses creation of metadata of the write data.

According to the present invention, a process for producing an amino acid using a microorganism in which aspartate aminotransferase activity is decreased or deleted, and which has the capability of producing and accumulating the amino acid is provided.

Method for producing L-amino acid using a microorganism with decreased aspartate aminotransferase activity

The present invention provides a process for producing a dipeptide or a dipeptide derivative using a phosphate donor, a substance selected from the group consisting of adenosine-5'-monophosphate, adenosine-5&#x2032;-diphosphate and adenosine-5&#x2032;-triphosphate, one or more kinds of amino acids or amino acid derivatives, and as enzyme sources, a protein having polyphosphate kinase activity, or a culture of cells having the ability to produce the protein or a treated matter of the culture, and a protein having the activity to ATP-dependently form the dipeptide or dipeptide derivative from one or more kinds of amino acids or amino acid derivatives, or a culture of cells having the ability to produce the protein or a treated matter of the culture.

Process for producing dipeptides or dipeptide derivatives

The present invention provides a protein which catalyzes the synthesis of a dipeptide different from L-Ala-L-Ala, a process for producing the protein which catalyzes the synthesis of a dipeptide, a process for producing a dipeptide using the protein which catalyzes the synthesis of a dipeptide, and a process for producing the dipeptide using a culture of a microorganism producing the protein which catalyzes the synthesis of a dipeptide or the like as an enzyme source.

Process for producing dipeptides

The present invention provides a protein having low-substrate-specific amino acid racemase activity; DNA encoding the protein; a recombinant DNA comprising the DNA; a transformant carrying the recombinant DNA; a process for producing the protein by using the transformant; and a process for producing a racemic amino acid which comprises allowing a culture of the transformant or a treated matter thereof as an enzyme source and an amino acid to be present in an aqueous medium to racemize the amino acid in the aqueous medium, and recovering the racemic amino acid from the aqueous medium.

The present invention relates to: a process for producing D-serine wherein a microbial cell which is modified to have a higher L-serine deaminase activity thanDH5&#x3b1; strain, a culture of said cell, or a processed product thereof is brought into contact with DL-serine in a DL-serine-containing medium to decompose L-serine, and the remaining D-serine is recovered from the medium; and a microorganism used for this production process. D-serine is a useful compound as a synthetic intermediate for useful medicaments such as D-cycloserine.
