Phaeoacremonium parasiticum 

Phaeoacremonium parasiticum is a darkly pigmented (dematiaceous) filamentous fungus that has gained attention in agarwood (Aquilaria spp.) resin induction research due to its role as a biotic stress agent.

Agarwood-focused profile you can directly use for R&D notes, SOP annexes, or farmer education (simplified where appropriate).

1. Basic Profile

  • Kingdom: Fungi
  • Phylum: Ascomycota
  • Growth form: Slow-growing, woody-tissue–colonizing fungus
  • Pigmentation: Dark (melanin-rich cell walls)
  • Natural habitat: Wood, vascular tissue, wounded tree xylem

2. Role in Agarwood Formation

In Aquilaria trees, P. parasiticum acts as a biotic trigger that:

  • Invades wounded xylem tissues
  • Causes localized vascular stress
  • Activates the tree’s defense metabolism
  • Stimulates sesquiterpene and chromone biosynthesis
  • Contributes to dark resin deposition around infection sites

👉 The fungus itself does not produce agarwood — the tree produces resin in response to fungal stress.

3. Why It’s Used in Agarwood Inoculation

Compared to aggressive pathogens, P. parasiticum is valued because it:

  • Colonizes slowly and controllably
  • Creates sustained stress, not rapid tree death
  • Promotes uniform resin spread when properly dosed
  • Works well in consortium-based inoculants (not solo)

This makes it suitable for professional, managed induction systems like:

  • MycoChem™
  • FusaPrime™
  • FusaTrinity™-type formulations

4. Best Use Strategy (Industry Practice)

Never used alone. Best results occur when combined with:

  • Other resin-associated fungi (e.g. Fusarium, Lasiodiplodia)
  • Abiotic primers (iron, mineral stressors)
  • Controlled drilling + dosing protocols

This creates a balanced biotic–abiotic induction system:

Stress → Defense → Resin → Maturation

5. Culturing Notes (High-Level, Non-Technical)

  • Grows on PDA, rice, or enriched organic substrates
  • Prefers woody carbohydrate sources
  • Slow growth = lower contamination risk
  • Requires clean handling and controlled inoculum density

(Technical culturing parameters should remain internal/proprietary.)

6. Safety & Compliance Notes

  • Not edible
  • Not for open environmental release without permits
  • Should be handled under controlled inoculation programs
  • Best deployed via licensed Contract Inoculation Services
