title: The metabolism of aromatic ring fission products by Bacillus stearothermophilus strain IC3.
abstract: Bacillus stearothermophilus IC3 degraded the meta cleavage product of catechol, 2-hydroxymuconic semialdehyde, to pyruvate and acetaldehyde via the 4-oxalocrotonate pathway. The pathway was identical to those previously delineated in several mesophilic organisms. However, all the enzymes showed activity at 55 degrees C and other properties (substrate specificities and effects of metal ions) also differed from those displayed by the mesophilic enzymes. All enzymes of this meta cleavage pathway, except the 2-hydroxy-6-oxohepta-2,4-dienoate hydrolase and 4-hydroxy-2-oxovalerate aldolase activities, were induced by growth on phenol.
