Destruxin Production in Metarhizium Brunneum Under Different Light and Nutrient Conditions

Destruxin A, B, and E concentrations from bioreactor batch cultures of the fungus Metarhizium brunneum BIPESCO 5 under five illumination conditions and two nutrient media. The dataset, authored by Jan Schobert and last updated in April 2026, shows production is affected by light wavelength in a nutrient-dependent manner. Shorter wavelengths like UV-A, blue, and green light enhanced destruxin A and B in a nutrient-rich medium but reduced them in a nitrogen-limited one.

Use Cases

• Modeling the influence of light wavelength on fungal secondary metabolite yield based on the described illumination conditions.
• Investigating nutrient-dependent metabolic responses in fungi based on the comparison between Sabouraud-4%-glucose and nitrogen-limited minimal media.
• Analyzing the stability of destruxin A:B ratios under different environmental stressors as described in the study.

Strengths

• Experimental design includes five controlled illumination conditions with specific wavelengths and intensities (e.g., 660 nm red light at 1.4 mW cm^-2).
• Directly compares metabolite production across two distinct nutritional states (nutrient-rich vs. nitrogen-limited media).
• Published under a permissive CC-BY-4.0 license, facilitating reuse.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small in size (969.0 KB), indicating a limited scope.
