What is the colony morphology of Bacillus Cereus?

Answer 1

Bacillus subtilis is a gram-positive bacterium, and its cells are rod shaped. The bacteria are usually cultured in Tryptone Soya Agar, and the colonies appear wrinkled, dull and raised. This bacterium colonizes vegetation and is prevalent in the soil.

Answer 2

B. subtilis spores have surface irregularities on the order of 7 to 40 nm in size and it will grow on any agar. Since they are motile, they can produce odd rotating structures especially if the agar is soft.

Answer 3

Bacillus cereus typically forms large, opaque, and irregularly shaped colonies with a slightly rough texture on agar plates. The colonies can also be flat or slightly raised, and they may have a matte or shiny appearance.

Answer 4

Colonies are large, irregular and flat with an undulate margin

Answer 5

elevation :umbonate

edge;entire with undulate

internal charectaristics :rough

color: creamy offwhite.

Answer 6

The morphology, which refers to the shape of the bacteria, would be rods (bacillus). The arrangement in relation to the other cells would be chains. They will also be large (mega).

Answer 7

Bacillus is a Gram Positive Rod shape irregular Bacteria.

Genus - bacilus

Species simplex

family - micobes

order- line

Answer 8

Cream coloured (on nutrient agar); Flat and circular with undulate margins.

Answer 9

circular and white
