It is described using terms like brittle, creamy, sticky and dry. Staphylococci are considered to have a creamy consistency, [1]: 173 while some Neisseria species are sticky, and colonies of diphtheroid bacteria and beta-hemolytic streptococci are typically dry. [1]: 167–8 Bacteria that produce capsules often have a slimy (mucoid) consistency.
The process of colony hybridization: growth of cell colonies, replication on filter, hybridization, and identification of desired colonies. Colony hybridization is a method of selecting bacterial colonies with desired genes through a straightforward cloning and transfer process. [1]
Therefore, a method for the detection of the insert would be useful for making this procedure less time- and labor-intensive. One of the early methods developed for the detection of insert is blue–white screening which allows for identification of successful products of cloning reactions through the colour of the bacterial colony.
Actinomyces species may form endospores, and while individual bacteria are rod-shaped, Actinomyces colonies form fungus-like branched networks of hyphae. [3] The aspect of these colonies initially led to the incorrect assumption that the organism was a fungus and to the name Actinomyces, "ray fungus" (from Greek actis, ray or beam, and mykes ...
Rapid identification of E. rhusiopathiae can be achieved with the API Coryne System. It is a commercial strip system based on a number of biochemical reactions for the identification of coryneform bacteria and related genera, including E. rhusiopathiae. The system permits reliable and rapid identification of bacteria and has been considered to ...
Colony morphology is very variable and a single strain may display multiple colony types, [17] [18] so inexperienced laboratory staff may mistakenly believe the growth is not pure. The organism grows more slowly than other bacteria that may be present in clinical specimens, and in specimens from nonsterile sites, is easily overgrown.

The plate count method relies on bacteria growing a colony on a nutrient medium so that the colony becomes visible to the naked eye and the number of colonies on a plate can be counted. To be effective, the dilution of the original sample must be arranged so that on average between 30 and 300 colonies of the target bacterium are grown.
