Saccharopolyspora spinosa

Saccharopolyspora spinosa is a species of actinobacterium first isolated from soil in a rum still in an abandoned sugar mill on the Virgin Islands. It was discovered and described by researchers Mertz and Yao while collecting specimens to be screened for novel antibiotics.^[1] It develops aerial, pale, yellowish pink hyphae and bears long chains of spores encased in spiny spore sheaths. It can also reproduce by fragmentation in an aqueous environment. Its type strain is A83543.1 (= NRRL 18395).
