A bacterium which produce hyaluronic acid complex was isolated from soil, and identified as Klebsiella sp. L-10. The maximal hyaluronic acid complex production was obtained when the strain was cultured at $37^{\circ}C$ for 18hrs with shaking in the optimal medium containing 0.1% yeast ext., 3% tryptone, 5% glucose, 10mM $K_2HPO_4$and $KH_2PO_4$, respectively and initial pH6.5 and the final hyaluronic acid complex production under the above condition was 1,400mg per liter of cultures.
