Bound cellobiose-biofilm causal graph claims to measured assays #1335

Source-based self-adversarial finding in Clostridium_Phytofermentans_Ecoli_Cellobiose_Biofilm_Consortium (CommunityMech:000196).

The graph combines planktonic substrate/ethanol measurements with biofilm biomass measurements, assigning all outputs to all three mechanisms. The primary Discussion expressly says biofilm cellobiose use and ethanol production were inferred, not directly measured. Polymer-cellulose process annotations also need separation from the tested cellobiose consortium.

The reciprocal necromass node has only a one-way pair; its peptide mediator is more certain than the assays. Oxygen partitioning is typed as colonization facilitation although the protective biofilm was established anoxically before oxygen exposure. The aggregate productivity endpoint is typed SYNTROPHY rather than distinguishing its constituent mechanisms.

Acceptance: preserve glucose-addition/cellobiase controls, both necromass-addition benefits, oxygen profiles, CFU evidence and condition-specific productivity. Account for all four nodes/three arrows, qualify mechanism contributions, distinguish qPCR from viability and biomass from EPS, and retain both canonical taxa. No new graph structure is required.

Primary: Park et al. 2020, PMID:33268782. Full main body, tables and captions read; images/supplements not inspected. Local ignored-inclusive search and 674 all-state issue titles/bodies checked; no duplicate exact graph issue in that scope. Broader enum #749/#752 remain separate. This is self-review, not independent approval.
