METHOD FOR PRODUCING POLYHYDROXYALKANOATE (PHAS) USING HALOBACTERIUM AND HALOBACTERIUM

摘要

Disclosed are a method for producing polyhydroxyalkanoate (PHAs) using a halobacterium belonging to the genus Halomonas, wherein the halobacterium can grow in a medium containing an inorganic salt and a single organic carbon source and having a pH of 8.8 to 11 and produce PHAs in an amount of 20% by weight or more based on the dry cell weight, and the halobacterium is cultured in a medium containing an inorganic salt and a single or plural organic carbon source(s) under an alkaline condition to produce PHAs in an amount of 20% by weight or more based on the dry cell weight; and the halobacterium belonging to the genus Halomonas which can grow in a medium containing an inorganic salt and a single organic carbon source and having a pH of 8.8 to 11 and produce PHAs in an amount of 20% by weight or more based on the dry cell weight.
