5.3 Differentiating strains for aroma and oil-grade resin

1. Key Concept

Not all fungal strains produce the same resin quality or aroma profile. Selecting the right strain—or combination—is crucial for premium agarwood.

  • Some strains stimulate rapid resin accumulation but lower aroma complexity
  • Others produce highly aromatic compounds but slower or shallower resin

2. Strain Effects on Resin

Strain TypePrimary EffectResin CharacteristicAroma & Oil Grade
Fusarium-based (e.g., FusaPrime™)Strong defense activationDeep resin veins, moderate speedHigh-quality oil, woody & balsamic notes
Multi-strain consortium (e.g., Harmonia™)Sustained & multi-pathway stimulationDense, layered resinComplex, premium aroma; best for oud oil
Yeast / non-Fusarium microbes (part of MycoChem™)Aroma enhancementModerate quantityRich sesquiterpenes & chromones; enhances fragrance intensity
Fast-colonizing aggressive fungiRapid resin initiationShallow or brittle resinOften less aromatic, may reduce oil quality

3. Factors Determining Aroma & Oil-Grade

  1. Fungal metabolism
    • Different fungi produce different enzymes and metabolites
    • Metabolites interact with tree compounds → unique aroma signature
  2. Colonization pattern
    • Deeper xylem colonization → higher resin density → better oil yield
  3. Synergy with chemical stress
    • Chemicals like FerroBoost™ + fungi → denser, richer resin
  4. Tree genetics & health
    • Some trees respond better to specific fungal strains

4. Practical Guidance for Inoculation

  • Use Fusarium strains (FusaPrime™) for deep, high-quality resin veins
  • Use a fungal consortium (Harmonia™) for aromatic complexity and higher oil grade
  • Combine chemical and biotic inoculants for best balance:
    • Abiotic → triggers fast response
    • Biotic → sustains resin formation and aroma diversity

5. Farmer-Friendly Analogy

“Think of fungi like chefs: one can make lots of food quickly (quantity), another can make gourmet dishes with complex flavors (aroma). Using the right team gives both quantity and premium quality.”
