Streptomyces avermitilis

This bacterium was discovered by Satoshi Ōmura in Shizuoka Prefecture, Japan.

[4] The genome consists of a single chromosome with a linear structure, unlike most bacterial genomes, which exist in the form of circular chromosomes.

[5] Avermectins are industrially derived from the fermentation products of S.

[1][6] Avermectin itself was discovered by the Satoshi Ōmura group[6] and first disclosed in Burg et al.

[1] One of the most widely employed drugs against nematode and arthropod infestations is the avermectin derivative ivermectin, as well as abamectin, a widely used insecticide and antihelmintic.
