An in vitro investigation of the antimicrobial activity of oxifulvic acid
in-vitro Grade C 2000
Authors: van Rensburg, C.E.J., van Straten, A., Dekker, J.
Journal: Journal of Antimicrobial Chemotherapy 46 : 853-854
Key Findings
- Oxifulvic acid (coal-derived FA) tested against S. aureus, E. coli, P. aeruginosa, C. albicans
- MIC data provided for each organism
- Humic substances account for 50% of dissolved organic carbon in stream water
- Fulvic acids are 9-10× more abundant in water than humic acids
- Coal-derived FA designated 'oxifulvic' to distinguish from naturally occurring FA
Key antimicrobial data paper providing MIC (minimum inhibitory concentration) values for oxifulvic acid against common pathogens. While the FA is coal-derived (not peat-derived), the chemical structure is comparable and the MIC data is widely cited for FA antimicrobial claims across all sources. Listed as TIER 3 in papers-to-find. Note: same research group (van Rensburg) later published the 2015 review already in the graph.
