Germicidins are a groups of natural products arising from Streptomyces species that acts as autoregulatory inhibitor of spore germination. In Streptomyces viriochromogenes low concentrations (200 pM) inhibit germination of its own arthrospores and higher concentrations inhibit porcine Na+/K+ -activated ATPase. Inhibitory effects on germination are also observed when germicidin from Streptomyces is applied to Lepidium sativum.
