Caption: Saccharopolyspora pogona - Gram-positive, aerobic, filamentous, rod prokaryote (bacterium). Saccharopolyspora pogona is a soil actinomycete that belongs to the Actinomycetes group and are bacteria that share many characteristics with fungi. They grow usually as filaments (chains of cells) and often branch to form a network of filaments (mycelium) in the soil. At the tips of filaments spore chains of indefinite length develop (not seen in this image). These soil bacteria are responsible for the musty odor of soil. A close relative, Saccharopolyspora spinosa, was first identified in 1982 and subsequently a new class of metabolite products (called spinosyns) were discovered under fermentation conditions by this actinomycete. These compounds have a unique mode of action coupled with a high degree of activity on targeted pests (especially catepillars and flies) with low toxicity to non-target organisms.
