SIMULATING GROWTH OF Bacillus ON AGAR PLATE
|
Abstract:
As Bacillus colony is an interdependent system, it was simulated that the metabolite restrained reproduction of bacillus by computer. For this purpose, diffusionrate k0 and the ratio r(r=Tr/Td)were used, Tr is the time for reproducing one grneration, Td is the time of one diffusing step, and the inhibition coefficient of metabolite on reproduction is m. At r=4.0, the different combination of k0 and m were studied comparatively and the results are in accord with the fact. Applying contour line and vectorgraph to analyze the concentration of matebolite, results showed that the interior of bacillus colony tends to become equilibrium and stable while the edge of bacillus colony is highly instable.
