Wood Antimicrobial Behavior Test Method

Some wood species have antimicrobial properties and a variety of methods are used to investigate them. For testing the effect of antimicrobial compounds, direct and indirect methods are used. Meanwhile, the survival of microbes is also tested on surfaces (or material in contact with microbes) to validate the safety of surfaces.

Natural material wood antimicrobials AMR Extraction Microbial survival Natural compounds Diagnostics Discovery

1. Introduction

Some wood materials show antimicrobial properties [1][2]. This potential can be employed for hygienic purposes[3][4][5]. Therefore, researchers and field experts study the wood material to investigate its hygienic safety and search for new natural antimicrobial compounds.

2. Pros and Cons of Methods Used to Test the Antimicrobial Behavior of Wood 

Many factors influence the choice of method selection to study the antimicrobial properties of wood materials[6]. These factors are related to the availability of experimental material, test samples, the purpose of study, and skills of handlers. The advantages and disadvantages of the methods are summarized in Table 1.

Table 1. Pros and cons of the methods used to study the antimicrobial behavior of wood material.


Method Name




Direct methods

Direct diffusion method
(Well and disc)

The wood material is directly placed on microbe-inoculated agar or in a well and incubated for recommended time
Presence of the zone of inhibition is considered a positive result

1. Rapid and time saving
2. Applicable for low amount of material
3. Adapted for screening

1. Disc preparation time
2. High variability for quantitative applications
3. Studies only the effect of agar-diffused chemicals
4. May require the sterilization of wood samples

Culture-based microbial survival test

Initial microbial quantity is inoculated on wood samples and after the incubation time, the microbes are recovered, cultured, and viable cells are counted

1. Can study the structural and chemical role of wood components
2. Qualitative and quantitative results
3. Applicable for low amount of material

1. Difficulty in recovering all microbes present in pores
2. Microbial quantification is an extra step needed
3. Only viable cells are identified, while there can be still non-viable infectious cells present


The behavior and distribution of inoculated microbes on wooden structures is observed via microscopy

1. Rapid and time saving
2. Applicable for low amount of material
3. Adapted for screening

1. May require the fixation of samples
2. Difficult to differentiate microbial structures from wooden structures
3. May require competencies of image analysis

ATP luminescence

The ATP of microbes on wood is measured

1. Rapid and easy
2. Applicable for low amount of material
3. Adapted for screening

1. Difficult to differentiate the microbial ATP from other organic debris
2. Adapted only for solid surfaces

Molecular biology methods

The quantity and viability of microbes is tested via nucleic acid amplification 

Accurately measures the microbial survival

1. Expensive
2. Require sophisticated handling 

Extractive based methods

Extractive-based diffusion and dilution method

Extractives are placed on agar or in agar wells, or in broth, after loading on filter paper discs or directly

1. Adapted for qualitative and quantitative antimicrobial studies
2. Specific chemicals can be extracted depending upon the solvent used

1. Involves chemical handling
Extra step of extraction
2. One solvent cannot extract all active components
3. Does not study the role of structure of wood


Extractives are loaded on a chromatographic layer, and then the diffusion of active chemicals is studied for their antimicrobial properties

1. Adapted for qualitative antimicrobial studies
2. Specific chemicals can be extracted depending upon the solvent used and identified on the basis of their diffusion on the chromatographic layer

1. Involves chemical handling and extraction
2. One solvent cannot extract all active components
3. Does not study the role of structure of wood
4. Not a quantitative method

Mass spectrometry

The total profile of microbes is measured

1. Applicable for a low amount of material
2. Accurately measure the content of the active ingredient

For more specific results, the identified compounds are supposed to be tested by other culture-based methods
