Bacterial morphologies of the four Bacillus species (samples 1, 5, 7 and 10) in exponential (exp) and stationary phase (sta). The pure cultures were grown in complete medium over night (exp) and three days (sta) at 28 °C. Microscopic analysis shows bacteria of the Genus Bacillus. Bar: 0,5 micrometry.
