摘要： It is intended to provide an ACT1 gene promoter represented by SEQ ID NO:9, a GAP3 gene promoter represented by SEQ ID NO:10, a PMA1 gene promoter represented by SEQ ID NO:11, and a TEF1 gene promoter represented by SEQ ID NO:12; a plasmid containing a gene expression unit containing such a promoter; transformed cells having the plasmid transferred thereinto; and a process for producing a copolymerized polyester by culturing the transformed cells.

摘要： It is intended to provide a method of purifying PHA, which is separated from PHA-containing microbial cells, at a high purity without causing a considerable decrease in its molecular weight. Namely, a method of purifying a 3-hydroxyalkanoic acid copolymer produced by a microorganism wherein a treatment with hydrogen peroxide is carried out while continuously or intermittently adding an alkali to an aqueous suspension containing the 3-hydroxyalkanoic acid copolymer separated from the microorganism to thereby control the pH value of the aqueous suspension.

摘要： A process for producing a poly-3-hydroxyalkanoic acid which comprises physically treating a microorganism cell suspension containing the poly-3-hydroxyalkanoic acid to crush the cells while continuously or intermittently adding an alkali to the suspension and then separating out the poly-3-hydroxyalkanoic acid.

摘要： Novel, useful and optically active 2-aralkyl-3-sulfonyloxy-1-propanols and 2-aralkyl-3-sulfonyloxypropionic acids prepared from optically active 2-aralkyl-3-acyloxy-1-propanols as the starting compound; and optically active 2-aralkyl-3-thiopropionic acids as an important intermediate for enkephalinase inhibitors. They are commercially advantageous, optically active sulfonic esters.
