Micoorganisms capable of lysing the cell wall of the red yeast Rhodosporidium were isolated from the soil obtained with in the precincts of the Yosida Shrine in Kyoto by screening for their ability to utilize the cell wall prepared from the red yeast as a carbon source which was seeded On an agar plate.The actinomycete strain YM1-1 supposed to be Streptomyces was found to Produce the lytic enzymes.The supernatant obtained by culturing of this soil microbe lysed the cell wall of the red yeast.The resulting crnde lytic enzyme fractions, after sedimentation by addition of ammonium sulfate, showed the high lytic activity toward the red yeast cell wall and laminarin, indicating mainly contained β-glucan-hydrizing activity, In addition, the actinomycete strain YM1-1 adhered to form flocculent clumps.The tendency to form clumps may facilitate the separation of the microorganism after a batch cultivation.
