Micrograph of Paenibacillus strain Y412MC10 cells showing individual cells and chains of cells. Cells were streaked on YT agar and incubated 18 hr. at 37°C. A colony was removed, re-suspended in sterile water and stained using a 5 μM solution of SYTO® 9 fluorescent stain in sterile water (Molecular Probes). Dark field fluorescence microscopy was performed using a Nikon Eclipse TE2000-S epifluorescence microscope at 2000× magnification using a high-pressure Hg light source and a 500 nm emission filter.
