摘要： A PHA copolymer which is slowly crystallized is improved in crystallization speed to improve the melt workability of the PHA copolymer in working such as injection molding, film molding, blow molding, fiber spinning, extrusion foaming or bead foaming, thereby improving the resultant articles in productivity. A method for the improvement is a method for producing a PHA mixture, including the step of culturing a microorganism having both of a gene encoding a PHA synthase that synthesizes a copolymer PHA (A) and that is derived from the genus Aeromonas, and a gene encoding a PHA synthase that synthesizes a PHA (B) different in melting point from the copolymer PHA (A) by 10°C or more to produce, in a cell of the microorganism, two or more PHAs different in melting point from one another by 10°C or more simultaneously.

摘要： A process for efficiently producing optically active amino compounds, mainly (R)-amino compounds, at a low cost by means of a microbial enzyme; a polypeptide suitable for use in the production process and having a stereoselective transaminase activity; and a DNA coding for the polypeptide. The process is characterized by comprising causing a transaminase to act on a ketone compound as an amino acceptor in the presence of a primary amine as an amino donor to stereoselectively transfer the amino group to thus obtain an optically active amino compound. The DNA contains a base sequence coding for a polypeptide having a stereoselective transaminase activity. The polypeptide can be obtained by incubating a microorganism belonging to the genus Arthrobacter.
