Mycological applications of x-ray microanalysis

Area of Science:

• Mycology
• Biochemistry
• Analytical Chemistry

Background:

• Aspergillus species are ubiquitous fungi with significant ecological and pathogenic roles.
• Understanding the elemental composition of fungi is crucial for various applications, including industrial biotechnology and medical research.

Purpose of the Study:

• To identify and quantify elemental composition in Aspergillus fumigatus and Aspergillus niger.
• To demonstrate the utility of X-ray microanalysis for elemental detection in fungal samples.

Main Methods:

• X-ray microanalysis utilizing wavelength dispersive spectroscopy (WDS).
• Detection of characteristic K alpha emission lines for elemental identification.

Main Results:

• Calcium, potassium, sulfur, phosphorus, and magnesium were detected in Aspergillus fumigatus.
• Calcium, potassium, chloride, sulfur, phosphorus, sodium, and magnesium were detected in Aspergillus niger.
• Elemental identification was confirmed through characteristic K alpha X-ray lines.

Conclusions:

• Wavelength dispersive X-ray microanalysis is effective for determining the elemental profile of Aspergillus species.
• The identified elements are integral components of fungal cellular structures and metabolic processes.
• This elemental data can inform future research on Aspergillus physiology and interactions.
