[2]: 518 The microbiologist examines the appearance of the colony, noting specific features such as size, colour, shape, consistency, and opacity. [1]: 165–8 A hand lens or magnifying glass may be used to view colonies in greater detail. [3]: 96 The opacity of a microbial colony can be described as transparent, translucent, or opaque.
The formation of patterns in the growth of bacterial colonies has extensively been studied experimentally. Resulting morphologies appear to depend on the growth conditions. They include well known morphologies such as dense branched morphology (DBM) or diffusion-limited aggregation (DLA), but much complex patterns and temporal behaviour can be fou
Spiroplasma is a genus of Mollicutes, a group of small bacteria without cell walls. Spiroplasma shares the simple metabolism, parasitic lifestyle, fried-egg colony morphology and small genome of other Mollicutes, but has a distinctive helical morphology, unlike Mycoplasma. It has a spiral shape and moves in a corkscrew motion.

Colony ontogeny refers to the developmental process and progression of a colony. It describes the various stages and changes that occur within a colony from its initial formation to its mature state. [14] The exact duration and dynamics of colony ontogeny can vary greatly depending on the species and environmental conditions.
An agar plate – an example of a bacterial growth medium*: Specifically, it is a streak plate; the orange lines and dots are formed by bacterial colonies.. A growth medium or culture medium is a solid, liquid, or semi-solid designed to support the growth of a population of microorganisms or cells via the process of cell proliferation [1] or small plants like the moss Physcomitrella patens. [2]
The morphology is quite variable and seems to depend, in part, on the age of the culture as the smallest form observed, coming from the elementary body, is 80nm to 100nm wide in diameter. [13] Different cell forms have been observed varying from coccoid cells to filaments and irregularly shaped structures with coccoid forms and ring- or disc ...
