Lethaia, EarlyView., 2021 Biomineralization is a generic term used to indicate biological‐mediated mineral formation. In carbonate mineralization, nucleation of crystals can be: (1) controlled directly by the organisms, like in the skeletal formation of most metazoans; (2) induced by microbial communities, by indirect precipitation mediated by their metabolic activities; or (3)

Directed Synthesis of Humic and Fulvic Derivatives with Enhanced Antioxidant Properties
Agronomy, 2021 Redox moieties, which are present in the molecular backbone of humic substances (HS), govern their antioxidant properties. We hypothesized that a directed modification of the humic backbone via incorporation of redox moieties with known redox properties ...

A Comprehensive Toxicological Assessment of Fulvic Acid
Evidence-Based Complementary and Alternative Medicine, 2020 Fulvic acid (FA), a humic substance, has several nutraceutical properties, including anti‐inflammation, antimicrobial, and immune regulation abilities. However, systematic safety assessment remains insufficient. In the present study, a battery of toxicological studies was conducted per internationally accepted standards to investigate the genotoxicity ...
