Distinguish early non-sucrose growth from later sucrose contribution in E. coli SPC #1853
Description
Finding
CommunityMech:000066. Early W/W delta-cscR growth was insensitive to induced export; source infers use of other photosynthates. Keep the existing carbon-support direction without sucrose exclusivity, preserve more-than-two-week continuous persistence, and qualify the proposed connection to cyanobacterial stimulation. Carbon feeding alone does not establish syntrophy. Remove 85% of fixed carbon from concentration; it is background exporter capability, not a dyad concentration. Preserve conditional positive reciprocal growth and unresolved mediator.
Evidence And Scope
https://pubmed.ncbi.nlm.nih.gov/28127397/
Whole six records and all existing graph nodes/directions reviewed. Primary Sesame, SynCom Y and shared SPC main text/captions were independently retrieved from Europe PMC and read; Azotobacter scope is the independently retrieved primary abstract, not full text. SPC supplement captions S1-S12 and figure pixels S2/S4/S5/S8 were additionally inspected; mathematical framework and remaining supplement images were not reviewed. No raw-data reanalysis.
Fresh all-state title/body dedup and ignored/hidden-inclusive local searches were performed. Matching #757/#714/#605/#310 bodies and related #529 were read; these do not duplicate the exact findings. PRs/comments were not exhaustively searched.

Sixteen nodes/nine existing directions retained; three nodes/three arrows removed. All 34 reviewed quotations match independent primary text and unchanged caches. Four in-memory claim-inflation probes were rejected at scientific assertions. Plain just-lint passed;explicit-runtime no-incremental mypy additionally checked. Source-read boundaries are recorded in the PR and ledger; non-graph follow-up #1855 remains open. Not independent approval; close only after protected-main merge.
