    摘要： Microbial polysaccharides can be liberated from their amine adducts by treating them with ammonia or a highly volatile amine in the presence of monohydric alkanols having 1 to 3 carbon atoms. It is advantageous to use the amine adduct in the form of a moist press cake in which it is isolated from fermenter broths. The free polysaccharides are obtained in a virtually quantitative yield.

    摘要： Phospholipids which are obtained within the framework of protein synthesis from fermentatively produced constituents of micro-organisms may be used, following a conversion into a water-dilutable form, for example by emulsification or by a chemical modification, such as saponification or sulfonation, as greasing agents for the greasing of leather and fur skins. In this capacity they are superior to vegetable and animal phospholipids.

    摘要： Ribonucleic acid in a mixture of crude nucleic acids is selectively hydrolyzed with 5'-phosphodiesterase to 5'-ribonucleotides without hydrolyzing desoxyribonucleic acid in the mixture. Selective hydrolysis is carrying out by contacting the crude nucleic acid mixture with 5'-phosphodiesterase immobilized on a polymer carrier. The crude mixture of nucleic acids is preferably obtained by aqueous extraction of microorganisms that have previously been extracted with ammonia and a lower alcohol to remove lipids. The polymer carrier is preferably a copolymer of glycidylmethacrylate, allylglycidylether, methacrylamide and methylene-bis-methacrylamide.
