Mechanistic insights into magnetite-enhanced Indoleacetic acid production by a mixed culture

Key Points

• Indoleacetic acid production is significantly enhanced in the presence of magnetite, indicating a positive effect on microbial metabolism.
• Metrics showed a 30% increase in indoleacetic acid levels when magnetite was introduced into the culture system.
• This analysis utilized mixed cultures to explore how magnetite influences metabolic pathways for enhanced production.
• Findings suggest that magnetite could serve as a biostimulant to improve nutrient uptake and bioproduct yield in microbial fermentation.
