Abstract
Constitutively dormant spores ofStreptomyces viridochromogenes germinate rapidly following treatment with 1.0% of the detergents Tween 80, sodium dodecyl sulfate (SDS), or sodium heptadodecyl sulfate. Six other detergents did not activate the spores. Activation by SDS was studied further. The spores were not activated following treatment with 0.09% or less of SDS for 60 min at 37°C. Activation was complete within 1 to 2 min of treatment with 1.0% SDS. the SDS-activated spores became deactivated during incubation in buffer. Deactivation was slow at 4°C and complete after incubation for 12 h at 25°C or 6 h at 37°C. The endogenous respiratory rate of the spores was increased 3-fold by SDS activation.
