WebColonies of Bacillus subtilis bacteria tend to form more wavy, fern-like edges to their colonies in the semi-solid medium. This is because of uneven distribution of nutrients. Those bacteria in a relatively nutrient-rich zone will be able to grow faster, and often grow in the direction of the nutrient source. WebIn conclusion, each particular chemical composition (organic matrix, inorganic filler, fluoride, and various metallic ions) can enhance or inhibit biofilm formation. Irregular topography and rough surfaces provide favorable interface for bacterial colonization, protecting bacteria against shear forces during their initial reversible binding and biofilm formation.

WebFor plating to a 100 mm plate, 100–200 µL of cell suspension generally works well. If very few colonies are anticipated, the entire cell suspension may be plated. However, if a very high number of colonies is expected, the cell suspension may be diluted up to 1:100 in S.O.C. medium before plating to avoid the formation of a bacterial lawn.

WebEach bacterium with a plasmid gives rise to a cluster of identical, plasmid-containing bacteria called a colony. Several colonies are checked to identify one with the right plasmid (e.g., by PCR or restriction digest). A colony containing the right plasmid is grown in bulk and used for plasmid or protein production. WebThe present study found differences in the number of S. mutans colonies between both groups of brackets in which CL showed more accumulation of bacteria. Some studies show that the SL brackets present better hygiene, 8,11 and they are less susceptible to bacterial colonization due to their shape and lack of wire or elastomeric ligatures. 12
