    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.
