How do you identify a bacterial colony?
Each distinct colony represents an individual bacterial cell or group that has divided repeatedly. Being kept in one place, the resulting cells have accumulated to form a visible patch. Most bacterial colonies appear white or a creamy yellow in colour, and are fairly circular in shape.

Most bacteria come in one of three basic shapes: coccus, rod or bacillus, and spiral. The cocci are spherical or oval bacteria having one of several distinct arrangements (see Fig. 2) based on their planes of division.
