Microalgae under environmental stress as a source of antioxidants
TL;DR: In this article, the authors discuss the mechanisms of stress and the corresponding antioxidant response in photosynthetic green microalgae and blue-green algae and show that each microalgal species responds differently to each stress, yielding an increase in enzymatic antioxidants such as superoxide dismutase, catalase, and glutathione peroxidase.

Colorimetry of Total Phenolics with Phosphomolybdic-Phosphotungstic Acid Reagents
TL;DR: In this paper, the use of Folin-Ciocalteu reagent rather than the FolinDenis reagent, gallic acid as a reference standard, and a more reproducible time-temperature color development period was investigated.
