  • Research on the roles played by gut microbes in human health is hampered by our inability to isolate and study them in pure cultures. Here, the authors describe an approach that allows targeted cultivation and rapid characterization of a significant proportion of human gut bacteria.

  • In an inter-laboratory study, the authors compare the accuracy and performance of three optical density calibration protocols (colloidal silica, serial dilution of silica microspheres, and colony-forming unit (CFU) assay). They demonstrate that serial dilution of silica microspheres is the best of these tested protocols, allowing precise and robust calibration that is easily assessed for quality control and can also evaluate the effective linear range of an instrument.
