title: [Formation of alpha-aminobutyric acid in Clostridium sordellii].
abstract: After a modified growth C. sordellii is able to ferment threonine as mono-substrate. It could be demonstrated for the first time that alpha-aminobutyric acid is definitely formed from threonine by clostridia. The pH-optimum of this reaction is greater than 8, the temperature optimum is greater than 28 degrees C. Further fermenting products are: glycine and presumably acetaldehyde.
