The primary object of the present invention is to provide a polymer synthase gene which is derived from mangrove soil metagenome, and the method for producing the useful copolymer by using this polymer synthase. Another object of the present invention is to provide an enoyl-CoA hydratase gene which is derived fromsp. CFMR 7, and the method for producing the useful copolymer, P(3HB-co-3HHx) with increasing the composition of 3HHx by the expression of this enoyl-CoA hydratase. In order to achieve these objects, an isolated polynucleotide encoding for a polypeptide with polymer synthase activity comprising an amino acid sequence set forth in SEQ ID NO: 1 or 3, or an amino acid sequence set forth in SEQ ID NO: 1 or 3 wherein one or more amino acids is replaced, deleted or added are provided.

In a turbidimeter for measuring a turbidity of a test solution to be measured i.e. culture solution in a fermentation apparatus, a semiconductor laser diode and a semiconductor photodiode are integrally arranged in a detection portion of the turbidimeter in such a manner that a laser beam emitted from the semiconductor laser diode is made incident upon the semiconductor photodiode through the test solution. Moreover, a protection circuit for the semiconductor laser diode and the semiconductor photodiode is also arranged in the turbidimeter to cut off a current flowed therethrough when an environmental temperature becomes above a predetermined temperature. Therefore, the turbidimeter can be made small in size and light in weight, and the turbidity can be measured accurately over wide range.
