Fluorescence images of single cells and micro-colonies of bacteria. Bacteria in compost are stained with EtBr (a, c and e) and SYBR Green II (b, d and f). Single bacterial cells in compost suspension before incubation (a and b) and micro-colonies developed after incubation on LB medium (c and d) observed under blue excitation by epifluorescence microscopy. Micro-colonies are also observed using micro-colony auto counting system (e and f) (in Wang et al. (2007) Fig. 3). (Color figure online)
