Expression

Organism Comment Expression
Saccharolobus solfataricus aspartate is identified as the most repressing sole carbon source for alpha-amylase production. Repression by glucose down
Saccharolobus solfataricus constitutively produced at low levels but can be induced further by starch addition up
Saccharolobus solfataricus glutamate is the most derepressing sole carbon source for alpha-amylase production up
