Bound Pseudomonas PHA and DNT graph outcomes by polymer and assay #1858

Finding

CommunityMech:000167. Preserve sucrose support, PHA production, DNT transformation and conditional cyanobacterial growth promotion. Replace PHB-specific graph grounding with the already-curated general PHA term: the 2017 study reports medium-chain-length products, not a PHB homopolymer. Production/remediation endpoints are not additional cross-feeding events. Keep cscAB, cscRABY/nitrate-blind and EM173 DNT implementations separate in wording; 8.8-fold is endpoint accumulation, not a production-rate measurement. DNT disappearance includes adsorption/reduction and is not proof of complete mineralization. Omics suggests unidentified exchange; it does not establish reverse sucrose transfer or a universal mutualism across all assays.

Evidence And Scope

https://pubmed.ncbi.nlm.nih.gov/28814973/
Whole three canonical records and all ten nodes/six existing arrows reviewed. Independently retrieved primary abstract for Halomonas; primary main text/captions for Shewanella, PHA, DNT and multi-omics; nitrate-study abstract and relevant coculture Results/Discussion. Exact read spans and limitations will accompany the decision ledger. No raw data or separate supplement/figure-pixel audit.

Fresh all-state issue title/body dedup and ignored/hidden-inclusive local searches performed. Read matching #1093/#258/#1851/#1669/#1606/#1605/#837/#836/#835 and related #529; no duplicate exact finding in that bounded scope. PRs/comments and all local historical reports were not exhaustively read.

Lifecycle

Address in dependent batch110; close only after protected-main merge. Self-adversarial review is not independent approval. Existing graph repairs add no topology or provider spend.
