Proposed Dual Inhibition Mechanism

🦠
Mechanism 1: Methanogenic Archaea Inhibition
Bioactive polysaccharide fractions from SSF-processed seaweed are proposed to disrupt the cell membrane integrity of methanogenic archaea (primarily Methanobrevibacter ruminantium), directly reducing CH₄-generating metabolic activity. SSF fermentation at 45°C modifies carrageenan structure, potentially enhancing bioavailability of inhibitory compounds.
⚗️
Mechanism 2: H₂ → Propionate Redirection
Fermentation metabolites from L. buchneri OV-5 and W. cibaria KACC 92499P are hypothesised to promote propionate-pathway bacteria, shifting H₂ from methanogenesis (CH₄ production) toward propionigenesis. This represents an alternative H₂ sink that maintains energy yield while reducing methane output.

Note: Proposed mechanisms are based on preliminary in-vitro observations and current literature. Causal confirmation requires in-vivo mechanistic studies (planned Q4 2026).

Fermentation Strains:
Registration & Functional Profile

Both strains are selected for thermotolerance at 45°C — a critical requirement imposed by the gel-forming property of carrageenan in Eucheuma denticulatum, which prevents liquid-phase fermentation and necessitates solid-state processing.

🧬
Lactobacillus buchneri OV-5
Registration: OV-5 (Internal Designation)
Species: Lactobacillus buchneri (Lb. buchneri) — lactic acid bacterium
Thermotolerance: Active at 45°C — essential for SSF at carrageenan gel-forming temperature
Proposed function: Primary lactic acid fermentation; bioactive compound modification via enzymatic activity; partial acidification of substrate
SSF role: Initiates fermentation cascade; produces acetate and 1,2-propanediol from carbohydrates; modifies substrate matrix
Safety profile: L. buchneri has a long history of safe use in feed fermentation (silage); classified as generally recognised as safe in fermented feed contexts
Status: Internal strain designation OV-5 — KIPO patent application includes strain characterisation data
🧫
Secondary Fermentation Strain (Patent-Protected)
KIPO Patent Application Strain 2 · KACC-Registered Patent Strain
Species class: Heterofermentative lactic acid bacterium — thermotolerant at 45°C
Institutional deposit: Formally deposited at the Korean Agricultural Culture Collection (KACC) — National Institute of Agricultural Sciences, RDA
Thermotolerance: Active at 45°C; adapted for solid-state conditions
Proposed function: Secondary fermentation; exopolysaccharide (EPS) production from seaweed polysaccharides; potential prebiotic activity in rumen
SSF role: Synergistic with primary strain; contributes to substrate matrix modification and bioactive compound profile shaping
KACC registration: Deposited with KACC — "P" suffix indicates patent strain deposit; verifiable through KACC database (kacc.rda.go.kr)
Status: Formally registered — institutional deposit confirms existence; strain identity will be publicly disclosed upon patent grant
Note on strain identity: Both fermentation strains are formally characterised and documented in the KIPO patent application. Strain identities are patent-protected and will be disclosed upon grant. KACC registration is verifiable through kacc.rda.go.kr. Functional roles are proposed based on species-class literature and preliminary in-vitro observations; in-vivo mechanistic confirmation is pending.

Substrate Biology

Why Spinosum + Cottonii?
Substrate Selection Rationale

The 70:30 Spinosum-to-Cottonii ratio is determined by carrageenan content, gel-forming behaviour, bioactive compound profile, and supply chain availability from Vietnam. This is not arbitrary — the ratio is a core patent claim.

Eucheuma denticulatum (Spinosum)
Primary Substrate · 70%
Eucheuma denticulatum
Spinosum — ι-carrageenan dominant
  • ι-carrageenan gels at room temperature → liquid fermentation impossible
  • Gel formation is why SSF is not merely preferred — it is the only viable process
  • High bioactive sulphated polysaccharide fraction
  • Commercial scale availability: Vietnam (Ninh Thuận, Khánh Hòa)
  • Established supply chain via AENON Vietnam agricultural network
Kappaphycus alvarezii (Cottonii)
Secondary Substrate · 30%
Kappaphycus alvarezii
Cottonii — κ-carrageenan dominant
  • κ-carrageenan — complementary gel-forming profile to ι-carrageenan
  • Contributes distinct sulphated polysaccharide fractions to final product
  • 30% ratio modulates total substrate viscosity and SSF matrix structure
  • Also commercially cultivated in Vietnam — same supply chain
  • Both species: bromoform-free (no halogenated compound concerns)

The specific 70:30 ratio and SSF process combination is the subject of patent Claim 2. Variations from this ratio require separate validation.
