Abstract

PURPOSE:To obtain the lysosphingolipid by a biological method comprising treating neutral sphingolipid with the cells (treated product) of a specific new genus Rhodococcus microorganism. CONSTITUTION:Neutral sphingolipid is treated with the cells of a genus Rhodococcus microorganism (e.g. Rhodococcus sp.strain GL-26) having an ability to produce an enzyme for converting the neutral sphingolipid into the lysosphingolipid. The obtained lysosphingolipid can effectively be utilized by introducing a carboxyl group-containing compound to the amino group of the lysosphingolipid.
