In the previous papers, it was reported that Staphylococcus aureus K. 363 produced the substance which promoted the leucocytes migration, and the conditions for the assay of L. P. S. were described.
In the present paper, the culture conditions for the production of L. P. S. were investigated. There was no difference in L. P. S. between living or killed bacteria and culture filtrate of K. 363 in the Media No. 5.
The L. P. S. is heat-labile, not precipitated by heavy metal such as Zn, and dialysable through cellophan bag.
The role of L. P. S. in inflammation was discussed.
