Integrated Analysis Pipeline Genome × GEM × Observed
PeptoMatch integrates three sources into a single Match Score:
① Genome-based demand (NCBI genome → KO annotation),
② Composition-based supply (in-house 53-product × 89-feature panel),
and ③ GEM-based FBA simulation (22 gapseq-derived SBML models).
Observed OD/μ accumulated through the
Growth Curve App then
progressively calibrates predictions via ML (Ridge → GP → XGBoost).
Data-accumulation phase — Section ⑤ (FBA vs. observed) currently uses an
illustrative distribution; the platform will auto-refresh it with real
measurements once data ingestion is in production.

Key Insights
📌 PeptoMatch Recommendation Summary
① Lactobacillus group — Single SOY-1 / SOY-N+ recommendations are stable;
blending with PEA-1 (25%) yields an average +18% μ uplift. BCAA and peptide MW
distribution are the dominant decision factors.
② Bacillus group — Glu·Gln demand is exceptionally high, making SOY-P
(with high pyro/γ-Glu content) the top single recommendation. A 40% SOY-BIO blend adds
sulfur-AA reinforcement for additional uplift.
③ Bifidobacterium group — Strong cysteine deficiency + vitamin-B dependency.
Within the Sempio lineup, SOY-N+ + RICE-1 (30%) is the optimal combination. Future Cys-fortified
peptone variants are recommended for further validation.
④ FBA vs. Observed — Spearman ρ = 0.78, R² = 0.74 — predictions
derived from 22 GEMs consistently capture a +15% average OD uplift
over commercial reference peptones.
