Bacterial colonies are defined as the assamblage of bacteria growing on a solid surface such as the surface of an agar culture medium, the assemblage often is directly visible, but also may be seen only microscopically.

Bacteria lives in colonies so what is the circumference of the colony?
for 3.14 time it would be 20mm
How do you distinguish between bacterial colonies and yeast colonies?
Under a microscope a yesat should have long filamentous hyphae whereas bacteria are simple rods or cocci. Acidic or antibacterial mediums should kill most bacteria most fungi (including yeasts) will remain living.
Who first developed the process of colony purification on solid media?
Robert Koch, he used potato slices to grow individual bacteria colonies.
In what ways do the macroscopic features of bacterial colonies differ from that of molds?
Bacteria looks more glossy, white or yellow Molds will have a fuzzy look to them
Larg colonies of bacteria know to exist in?
large colonies of bacteria know to exist in
Do Bacteria always live in colonies?
Yeah, they do.
Harmless bacteria produced colonies with what edges?
smooth
Harmless bacteria produced colonies with edges?
Smooth
How many cells do bateria have?
Bacteria are unicellular organisms; one cell. Some bacteria for cooperative colonies though.
What are the transgenic bacteria?
Trangenic bacteria are bacterial colonies which are genetically modified by deleting or adding a particular gene sequence.
What is incubation used for in culturing?
When doctors are trying to determine what bacteria is causing an illness they sometime get a sample from the person and swab it on a shallow glass dish that contains a material the bacteria like and grow on. Once the bacteria has grown into colonies technicians look at them under a microscope to determine what the bacteria is. The process of growing the colonies of bacteria is called culturing
What are clusters of bacteria called?
Bacteria that multiply quickly and have no motility form colonies in a cluster. However, so bacteria that have motility do not form clusters.
Is salmonella microscopic?
Yes, but you can sometimes see colonies of salmonella bacteria.
The strain of bacteria that caused pneumonia grew into what colonies on culture plates?
The disease-causing strain of bacteria grew into smooth colonies on culture plates, whereas the harmless strain produced with rough edges.
What field of biology is observing colonies of bacteria?
microbiology normal the bacteria are grown on agar plates atsrting out with a dense area and spread out to in the end isolate individual colonies and have some hope of identifying them
Will isolated colonies always be in the second sector on the streak plate?
No. It depends on the number of bacteria present in the initial sample. If the number of bacteria in the initial sample are limited, you may get isolated colonies in the first streak. If the number of bacteria in the sample are high, it may take several streaks before the sample is diluted to the point where isolated colonies are evident.
