Coloured scanning electron micrograph (SEM) of 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. These soil bacteria are responsible for the musty odour 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. These compounds have a unique mode of action coupled with a high degree of activity on targeted pests (especially caterpillars and flies) with low toxicity to non-target organisms.
