    摘要： A method for the anaerobic fermentation of organic waste materials in a digestion zone, which method comprises introducing into the zone algae produced externally of the zone, and/or at least part of the liquid substrate in which such algae have been grown.Apparatus for anaerobic fermentation consisting essentially of a liquid storage tank comprising an inner bag-like container made of flexible material and provided with inlet and outlet means for the introduction of feed materials and the simultaneous removal of liquid and gaseous products, an outer supporting wall or frame, and at least one layer of insulating material arranged between the outer wall of the frame and the container.

    摘要： The present invention relates to a process for producing deoxyribonucleic acids and/or ribonucleic acids (hereinafter designated as high-molecular nucleic acids), which is characterized by culturing aerobically a microorganism capable of producing deoxyribonucleic acid and/or ribonucleic acid in a culture medium containing hydrocarbon or carbohydrate as main carbon source, accumulating a substantial amount of deoxyribonucleic acid and/or ribonucleic acid and recovering the accumulated deoxyribonucleic acid and/or ribonucleic acid from the fermentation liquor.

    摘要： N-acetyl-3-(3,4-dimethoxyphenyl)alanine is converted by the enzymatic action of an acylase from Aspergillus oryzae to 3-(3,4dimethoxyphenyl)-L-alanine, leaving as an unreacted byproduct Nacetyl-3-(3,4-dimethoxyphenyl)-D-alanine. The process is preferably carried out in the presence of ammonia to adjust the pH to the desired value within the range of 6.0 to 9.0, and in the presence of cobaltous ions in a concentration of 10 4 to 5 X 10 2 M. 3-(3,4-Dimethoxyphenyl)-L-alanine is converted to 3(3,4-dihydroxyphenyl)-L-alanine by cleavage of the ether groups.
