Single-cell Bacterium Identification with a SOI optical microcavity
Applied Physics Letters, 2016Co-Authors: M. Tardif, J.-b. Jager, P. Marcoux, K. Uchiyamada, E. Picard, E. Hadji, D. PeyradeAbstract:Photonic crystals and microcavities act as on-chip nano-optical tweezers for Identification and manipulation of biological objects. Until now, optical trapping of virus and bacteria has been achieved and their presence in the vicinity of the optical resonator is deduced by the shift in the resonant wavelength. Here, we show trapping and Identification of bacteria through a properly tuned silicon on insulator microcavity. Through the spatial and temporal observations of bacteria–cavity interaction, the optical Identification of three different kinds of bacteria is demonstrated.

isolation and characterization of a fluorene degrading Bacterium Identification of ring oxidation and ring fission products
Applied and Environmental Microbiology, 1992Co-Authors: M Grifoll, M Casellas, J M Bayona, A M SolanasAbstract:Abstract An Arthrobacter sp. strain, F101, able to use fluorene as the sole source of carbon and energy, was isolated from sludge from an oil refinery wastewater treatment plant. During growth in the presence of fluorene, four major metabolites were detected and isolated by thin-layer chromatography and high-performance liquid chromatography. 9-Fluorenol, 9H-fluoren-9-one, and 3,4-dihydrocoumarin were identified by UV spectra, mass spectrometry, and 300-MHz proton nuclear magnetic resonance. The fourth metabolite has been characterized, but precise Identification was not possible. Since strain F101 is not able to grow with fluorenone, two different pathways of fluorene biodegradation are suggested: one supports cell growth and produces 3,4-dihydrocoumarin as an intermediate and probably the unidentified metabolite, and the other produces 9-fluorenol and 9H-fluoren-9-one and appears to be a dead-end route.
