15/10/1992 · Bacillus subtilis colonies show periodic growth on agar plates. The organism has been observed to show several colony morphologies including diffusion-limited aggregation (DLA) type, dense branching morphology (DBM), Eden type, and spreading without producing openings.
01/01/1994 · The bacterium grew to a fractal colony through the diffusion-limited aggregation process, a round colony reminiscent of the Eden model, a colony with a straight and densely branched structure similar to the dense branching morphology, a colony spreading without any openings, and a colony with concentric rings, on plates with various agar and nutrient concentrations.
Positive control organism: Bacillus subtilis Selective for Gram negative Organisms Eosin–Methylene Blue (EMB) Agar is a differential medium for the detection of Gram negative enteric bacteria. The medium contains peptone, lactose, sucrose, dipotassium phosphate, eosin and methylene blue dyes.
