    Abstract: 2. Animal feed additives based on fermentation broth further contain, in addition to the additive, other fermentation broth constituents. Such products, after spray-drying, generally have an excessively low bulk density and/or are sticky. To granulate these products, processing aids have therefore been added, e.g. perlite or sawdust. Alternatively, such products have been dewatered by azeotropic distillation with paraffin oil to give granules. The object of the invention is a highly concentrated animal feed additive which, in particular, is to have a bulk density of at least 550 kg/m and a standardisable active compound content. 2.2. By pelletising, stable granules can be produced from an animal feed additive-containing fermentation broth if the fermentation product is contained at at least 33% by weight. Granules can particularly readily be produced by pelletising if the pellets are built up of at least 30% by weight fine grain with at least 70% by weight having a particle size

    Abstract: Fermentative preparation of amino acids for animal feed supplement purposes is a complex process, since the amino acid is present in the fermentation broth at 40 to 90 %, up to 10 % of proteins, 8 % of carboxyl acid with less that 8 C, up to 10 % of sugar, up to 5 % of fats and oils, 3 to 30 % of mineral substances. The method consists of the cultivating at least one microorganism, producing at least one amino acid in fermentative medium, comprising at least one source of carbon and nitrogen, mineral substances and trace elements, at the second step fermentation consists of at least 30 % of fermentation time is concentration of valuable sugar in fermentative medium max. 0.3 % wt. and at the end to obtain fermentative tan-liquor with valuable sugar max. 1g/l, at the third step there are partly reduced microorganisms of the biomass to max. 10 % wt. in dry matter and at the fourth step the additive is dried straight from fermentative tan-liquor.

    Abstract: The gaseous mixture resulting from the catalytic reaction of 3-methylpyridine with ammonia and oxygen is treated with water to recover 3-cyanopyridine. The treatment takes place in two steps. In the first step there is used a temperature of about 30 to 60.degree.C and in the second step at a temperature about 10 to 30.degree.C lower than in the first step.

    Abstract: The present invention provides a process for producing pyridines which are aromatically and heteroaromatically substituted in the 2 and 3 position, in which aromatically and heteroaromatically substituted ketones, which have at least one reactive methylene group adjacent to the keto group, are reacted with aliphatic oxo compounds, which have an unsaturated carbon bond adjacent to the oxo group, in the gas phase in the presence of ammonia and in the presence of a catalyst having dehydrating and dehydrogenating properties at temperatures from approximately 250 to550.degree.C.
