Fig. 8From: SpoVG is an important regulator of sporulation and affects biofilm formation by regulating Spo0A transcription in Bacillus cereus 0–9The colonial morphology of B. cereus 0–9 and its spo0A mutants. Tested strains were seeded on NA medium and cultured at 30 °C for 2 days. And then, the image of each colony was shoot by stereomicroscope.
