Proposed Undergraduate Thesis Title:
“Development and Evaluation of a Bio-Inoculant Formulation of Fusarium oxysporum for Artificial Induction of Agarwood (Aquilaria malaccensis) Resin Formation”
I. Introduction
Background of the Study
Agarwood (Aquilaria malaccensis) produces one of the most valuable natural resins in the world, used in perfumery, incense, and traditional medicine. Resin formation in Aquilaria is typically induced by biotic stress such as fungal infection, particularly by Fusarium oxysporum. However, uncontrolled infection can damage trees and reduce yield quality.
Developing a bio-inoculant formulation that standardizes resin induction while maintaining tree health is vital for sustainable agarwood production. This study aims to develop and evaluate a controlled inoculant using Fusarium oxysporum under laboratory and field conditions.
II. Statement of the Problem
- How can Fusarium oxysporum be effectively isolated, cultured, and formulated into a stable bio-inoculant for agarwood induction?
- What is the optimal inoculation method and concentration for inducing oleoresin formation without causing extensive tree damage?
- How does the bio-inoculant affect resin yield and quality compared to natural infection or chemical induction methods?
III. Objectives
General Objective:
To develop a standardized bio-inoculant formulation of Fusarium oxysporum for enhanced resin formation in Aquilaria malaccensis.
Specific Objectives:
- Isolate and identify indigenous Fusarium oxysporum strains from naturally infected Aquilaria trees.
- Determine the optimum growth conditions and carrier materials for bio-inoculant formulation.
- Evaluate the effectiveness of different inoculation techniques (drilling, wounding, injection) on resin induction.
- Assess the biochemical characteristics of induced resin (color, aroma, GC-MS composition).
IV. Significance of the Study
- Scientific contribution: Provides baseline data for controlled microbial inoculation in agarwood production.
- Economic relevance: Promotes sustainable, farmer-friendly resin induction methods.
- Environmental impact: Reduces dependency on chemical inducers or destructive wounding practices.
- Industrial potential: Supports the development of local bio-products (e.g., BarIno FusaTrinity™ under Crown Organic Fertilizers Inc.).
V. Review of Related Literature (abbreviated)
- Agarwood formation mechanisms: (Okudera & Ito, 2009; Mohamed et al., 2014)
- Role of Fusarium oxysporum in Aquilaria infection: (Chhipa et al., 2017; Liu et al., 2013)
- Artificial induction techniques: drilling, chemical stimulation, fungal inoculation (Persoon et al., 2021)
- Bio-inoculant formulation: carrier media (talc, peat, lignite, rice bran) and microbial stabilization methods (Rai et al., 2015).
VI. Methodology
1. Isolation and Identification
- Collect wood samples from infected Aquilaria trees.
- Culture on PDA (Potato Dextrose Agar).
- Morphological and molecular identification (ITS sequencing).
2. Bio-Inoculant Formulation
- Prepare fungal biomass in liquid culture.
- Mix with organic carriers (sterilized rice bran, molasses, and MgCl₂-sugar nutrient mix).
- Test viability and shelf life at room temperature.
3. Inoculation Experiment
- Select 3–5-year-old A. malaccensis trees.
- Apply inoculant through drilling or syringe injection at standard depths.
- Compare with control groups (no inoculation and chemical induction).
- Monitor resin formation at 1, 3, and 6 months.
4. Data Collection
- Visual resin grading (color, spread, hardness).
- Weight of resinous wood (g per tree).
- GC-MS analysis for aromatic compound profiling (agarospirol, benzylacetone, etc.).
5. Statistical Analysis
- ANOVA to test differences among treatments.
- Post-hoc analysis (Duncan’s Multiple Range Test) for mean comparisons.
VII. Expected Results
- Optimized Fusarium oxysporum strain with high resin-inducing potential.
- Effective, low-damage inoculation method for sustainable resin formation.
- Biochemically confirmed resin comparable to natural agarwood quality.
- Prototype bio-inoculant product suitable for commercialization.
