Impact on the Fe redox cycling of organic ligands released by Synechococcus PCC 7002, under different iron fertilization scenarios. Modeling approach
TL;DR: In this paper, the role played by the natural organic ligands excreted by the cyanobacteria Synecococcus PCC 7002 on the iron redox chemistry was studied at different stages of growth, considering changes in the organic exudation associated with growth under two different scenarios of iron availability.
Biomass and its potential for protein and amino acids : valorizing agricultural by-products
TL;DR: The results showed that protein extractability depended crucially on the type of biomass used, and most proteins were extracted using proteases that worked at acidic pH assisted protein extraction, which is in line with the literatures study.

Antibacterial and anti-hyperlipidemic activities of the brown alga Hormophysa cuneiformis from Ad Dammam Seashore
TL;DR: In this paper, a laboratory experiment was conducted to test antibacterial activity of ethanol extract of the brown alga Hormophysa cuneiformis against three types of Gram positive and three of Gram negative bacteria, where extracts of this alga proved efficient activity against these pathogenic bacteria species ranged between medium and high suppression action.

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.

Antioxidant activity applying an improved ABTS radical cation decolorization assay.
Roberta Re,Nicoletta Pellegrini,Anna R. Proteggente,Ananth S. Pannala,Min Yang,Catherine Rice-Evans +5 more
TL;DR: A method for the screening of antioxidant activity is reported as a decolorization assay applicable to both lipophilic and hydrophilic antioxidants, including flavonoids, hydroxycinnamates, carotenoids, and plasma antioxidants.

Oxidants, oxidative stress and the biology of ageing.
Toren Finkel,Nikki J. Holbrook +1 more
TL;DR: Evidence that the appropriate and inappropriate production of oxidants, together with the ability of organisms to respond to oxidative stress, is intricately connected to ageing and life span is reviewed.

Antioxidant activity and phenolic compounds of 112 traditional Chinese medicinal plants associated with anticancer.
TL;DR: Traditional Chinese medicinal plants associated with anticancer might be potential sources of potent natural antioxidants and beneficial chemopreventive agents, and contain significantly higher levels of phenolics than common vegetables and fruits.
