Saccharopolyspora spinosa
species of bacterium
Saccharopolyspora spinosa is a species of actinobacterium first isolated from an abandoned sugar mill in the Virgin Islands. It was discovered and described by researchers Mertz and Yao while collecting specimens to be screened for novel antibiotics. 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).
Saccharopolyspora spinosa is the source of a family of insecticidal compounds called spinosyns. They act as neurotoxins by activation of nicotinic acetylcholine receptors in insects. The insecticide Spinetoram is composed of two synthetic derivatives of spinosyns.

This brief starts where responsible research should: with the source description of “Saccharopolyspora spinosa” as species of bacterium. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of bacterium. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated May 7, 2026. The linked authority identifier is Q16992363. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2011.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
