    摘要: A yeast strain with high power to produce alcohol by fermentation is produced by a method comprising directly conjugating the haploid of the strain No. 909-1 with each tetrad of the ascospores of the strain No. 180 by spore-to-cell mating, acclimating the resultant zygote in the medium of waste after alcohol fermentation, and acclimating the surviving cells of the zygote in the medium of the beet molasses containing 2-deoxyglucose. The yeast strain produced is designated as Strain M-9 (FERM BP 1481) of genus Saccharomyces cerevisiae. Alcohol is produced by culturing the Strain M-9 in a medium of beet molasses.

    摘要: The ventilating fan system comprises an air flow passage including a duct for guiding the air in a room to outside and a ventilating fan arranged in the air flow passage; whereby said ventilating fan is an inversion type ventilating fan, in which opposed rotating blades arranged in a direction perpendicular to flowing direction of the air are rotated in reverse directions, and the ventilating fan is arranged at an end portion of the air flow passage closer to outside and sucks the air in the room and discharges it to outside.
