Overview

Analyzing antioxidant enzymes and growth rates in cyanobacteria strains suggests potential for biofertilizers and therapeutics.

Key Points

  • This research examines the antioxidant status and growth rates of various cyanobacteria strains in nitrogen-free media.
  • Analyzed antioxidant enzyme activities and growth rates in Nostoc and Desmonostoc strains.
  • Assessed retinol and α-tocopherol content, fatty acid composition, and cellular mechanisms under nitrogen limitation.
  • Conducted principal component analysis to evaluate metabolic adaptations.
  • Nostoc sphaeroides showed the highest growth rate and glutathione peroxidase activity.
  • Nostoc commune and Desmonostoc caucasicum exhibited greater superoxide dismutase activity.
  • Desmonostoc caucasicum demonstrated unique adaptive strategies, indicated by increased succinate dehydrogenase activity.
