X-ray photoabsorption-induced processes within protonated rifamycin sodium salts in the gas phase [PDF]
, 2021 Up to now, the response of antibiotics upon ionizing radiation has been very scarcely reported. Here, we present the results of X-ray photoabsorption experiments on isolated rifamycin, a broad-range antibiotic against Gram-positive and Gram-negative ...

Discovery of a new source of rifamycin antibiotics in marine sponge actinobacteria by phylogenetic prediction [PDF]
, 2006 Phylogenetic analysis of the ketosynthase (KS) gene sequences of marine sponge-derived Salinispora strains of actinobacteria indicated that the polyketide synthase (PKS) gene sequence most closely related to that of Salinispora was the rifamycin B ...
