A novel bacterium, Cellulomonas uda CB4, and production of cellulase by cultivation of the bacterium on a medium containing a cellulosic material are disclosed.

Process for production of cellulase

A physiologically active polysaccharide is prepared by treating autolysis-insoluble matters of yeasts of Saccharomyces with a yeast cell wall-lytic enzyme and obtaining a water-soluble physiologically active substance in the resulting solution-fraction. The novel polysaccharide possesses specific physical and chemical properties, and provides a chemotherapeutic agent such as a carcinostatic agent which can be used in the treatment of implanted tumors in mice and rats and an interferon inducer.

Physiologically active polysaccharides, production and uses thereof

Prodigiosin, an antibiotic, is effectively produced by culturing a novel Serratia marcescens R-2 strain. A synthetic culture medium is also provided, which contains a higher fatty acid having 12 to 18 carbon atoms, a salt thereof or an ester thereof as the sole or main source of carbon and in which a strain of Serratia marcescens having the abilities to assimilate the source of carbon and to produce prodigiosin can be cultivated to obtain prodigiosin.
