Source-derived summary

Knoellia subterranea is a species of Gram positive, nonmotile, non-sporeforming bacteria. The bacteria are aerobic and mesophilic, and the cells can be irregular rods or coccoid. It was originally isolated from an air sample from cave soil from Reed Flute Cave in Guilin, China. K. sinensis was one of the first described species of Knoellia, being discovered along with the type strain K. sinensis. The species name refers to its subterranean isolation location

The optimum growth temperature for K. subterranea is 28-37 °C, but cannot grow at 42 °C. The optimum pH is 5.0-9.0.

Editorial summary

“Knoellia subterranea” enters the record as species of bacterium. Crown Archives preserves that source wording while asking what Knoellia, subterranea and species can confirm, complicate or overturn.

Editorial reviewUseful for establishing the present vocabulary of the subject while preserving a route back to the evidence on which that vocabulary rests. The current 94-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its strongest next move is a source search built around Knoellia, subterranea and species.
Editorial analysis

Why this record matters

“Knoellia subterranea” is worth following because a concise public description often conceals a longer documentary argument. Here, Knoellia, subterranea and species provides the most credible route into that argument.

Evidence profile

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 Oct 29, 2023. The linked authority identifier is Q21273978. None of the 0 selected statements returned an explicit reference.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. 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.
