[Problems] To provide a method for efficient production of an acetic acid bacterium-type ceramide which is expected to have physiological effects such as making skin beautiful, by increasing the content of ceramide contained in cells of an acetic acid bacterium. [Means for Solving the Problems] There has been developed a method for increasing the acetic acid bacterium-type ceramide where the content of the acetic acid bacterium-type ceramide in cells of the acetic acid bacterium is able to be made as high as to a level of 10 to 30 fold by such a manner that acetic acid bacterium after finishing the culture is kept at the pH of 2.0 to 8.0 and the temperature of 4 to 70° C. for 3 hours to 7 days. As to the acetic acid bacterium used, Acetobacter malorum NCI 1683 strain (FERM BP-10595) or Gluconacetobacteri hansenii NCI 1468 strain (FERM BP-10596) is preferred.
