Abstract
To evaluate the suitability of Bacillus subtilis as a production host of heterologous proteins for pharmaceutical purposes, we assessed the biological activity of this bacterium and its major cell envelope components, lipoteichoic acid (LTA) and peptidoglycan-teichoic acid complex (PG-TA) in several eukaryotic effector assays. LTA and PG-TA were found to be non-toxic for mice and guinea-pigs in a short-term toxicity assay. PG-TA was weakly pyrogenic and weakly mitogenic. Both LTA and PG-TA acted as immunologic adjuvants in mice and when injected in mice, also caused an increase in the number of granulocyte-monocyte colony-forming cells in the bone marrow probably via stimulation of production of granulocyte-macrophage colony-stimulating factor.
