Proposed biodegradation pattern of neomycin using R. ericae, where (B)–(D) show possible structural isomers of oxidation products of D-ribose (A). The tentative identities of the oxidation products were verified by UHPLC-Q-TOF MS analyses. Extracted ion chromatograms (Neo1Re, 168 h) at m/z 133.0498 (A), 148.0608 (B), 129.0185 (C) and 147.0291 (D)
