    摘要: At least one type of excretable, thermostable amylolytic enzyme, such as amylase and pullulanase, can be recovered from a culture medium in which thermophilic anaerobic bacteria, such as Thermoanaerobacter finii or Thermobacteroides acetoethylicus, are propagated anaerobically in continuous culture, in the presence of a higher saccharide as carbon source, such an enzyme having a high stability at temperatures between 60.degree. and 70.degree. C. in absence of metal ions and substrate and under aerobic conditions.
