title: [Preparation of an active strain of Bacillus licheniformis--producer of thermostable alpha-amylase].
abstract: A highly potent strain of Bacillus licheniformis 103 that synthesized thermostable alpha-amylase with temperature and pH optima of 90-95 degrees C and 6.0-8.5, respectively, was obtained by mutagenesis and selection. The composition of fermentation media and conditions for submerged cultivation of the producer were optimized. alpha-Amylase whose activity reached 260 U/ml was obtained in laboratory fermenters.
