Isolate coding: RnRn isolated from weathered rocks on RBC, RnPn isolated from weathered rocks on PCA, SnPn, isolated from swab streaking on PCA, BPn isolated from swab supernatant on PCA. Isolate with the same phenotype: based on oxidase and catalase reaction, colony morphology, Gram stain and cell morphology, resistance to the EOs tested. Bold numbers indicate the lower inhibitory concentration.
