The Terminator

Streptomyces griseus is a hardy bacteria capable of eliminating nearly all competition in the soil it lives. It is, therefore, no surprise that it contributes 70% of naturally occurring antibiotics.[1]
Kingdom: Bacteria
Genus: Streptomyces
Species: S.griseus

It has a particularly thick peptidoglycan layer protecting its membrane that resists lysis. Even a 6 hour exposure to lysozyme enzymes failed to break the cell wall or prevent growth. Not only does it protect soil from bio contaminants but it also has a thick mycelium that prevents erosion and even digests numerous compounds such as chitin and lignocellulose, thus greatly improving soil quality. It also contributes the earthly smell via production of a compound known as geosmin.[2]
