Amycolatopsis orientalis (previously known as Streptomyces orientalis)^[2] is a Gram-positive bacterium in the phylum Actinomycetota.^[1]^[3] It produces several substances with antimicrobial properties, including the antibiotic drug vancomycin.^[4]^[5]

History

A. orientalis was originally discovered by Edmund Kornfeld, an organic chemist at Eli Lilly and Company, in a soil sample gathered by a missionary from forests on the island of Borneo. The antibiotic vancomycin was first isolated from the bacteria in 1953.^[5]^[6]
