<p>A primary object of the present invention is to provide an inexpensive, simple, and highly efficient process for producing 3-hydroxybutyric acid or a salt thereof. This object can be achieved by a process for producing 3-hydroxybutyric acid or a salt thereof, the process comprising the following steps (1) to (3):
(1) step 1 of culturing one or more halophilic bacteria belonging to the genus Halomonas under aerobic conditions in a medium containing an inorganic salt and one or more organic carbon sources;
(2) step 2 of changing the culture conditions in step 1 from aerobic culture to microaerobic culture, and culturing bacterial cells of the halophilic bacteria to produce 3-hydroxybutyric acid or a salt thereof in a culture medium; and
(3) step 3 of collecting the 3-hydroxybutyric acid or the salt thereof from the culture medium obtained in step 2.</p> |
