摘要:
Dry microorganism cultures comprising at least one microorganism species in carrier-bound form are present in the form of particles which a) have a particle size of at least about 0.1 mm and b) are compressed; processes for preparing dry microorganism cultures and their use for preparing foodstuffs and feedstuffs are also claimed.
摘要:
The present invention relates to the preparation of isomerically pure substituted cyclohexanols starting from a mixture of cis/trans substituted cyclohexanols which comprises reacting the cis/trans mixture of a substituted cyclohexanol with a dicarboxylic acid anhydride in the presence of a lipase, to give the trans semi-ester which is separated off from the unreacted substituted cyclohexanol cis isomer.
摘要:
The invention relates to the area of health-beneficial preparations and production methods thereof, in particular to the use of thermally pre-treated Lactobacillus preparations having specific bonding capacity for Streptococcus mutans for caries prophylaxis. The invention further relates to the Lactobacillus preparations and thermal pasteurization.

摘要:
A strain of Bacillus subtilis which is a tryptophan auxotroph, resistant to sulfaguanidine and flourotryptophan and produces anthranilic acid in a nutrient solution containing L-tryptophan, and process for the preparation of anthranilic acid by fermentation.
摘要:
A process for the preparation of optically pure D- or L-lactic acid by fermentation of an aqueous nutrient medium, which contains nitrogen, vitamins, aminoacids, sugars and trace elements, by means of a microorganism, at pH 4-6, wherein the nutrient medium contains brewers' yeast as the source of nitrogen, vitamins, aminoacids and trace elements.
