Bacteria or any organism have basic requirement to survive grow and multiply i.e. is food and nutrition. Bacterial colonies arise when bacterial cell get sufficient amount of nutrient and favourable condition like optimum temprature and pH. These factor influence the multiplication of bacterial cells which leads in the formation of their colonies, this can be observed in laboratory by growing bacterial cells on nutrient agar medium and on incubate it in incubator at specific temp. the colonies on petriplates of nutrient agar shows distince morphology by different bactreial species.

What is used to grow colonies of bacteria away from open air contaminants?
A Petri dish is commonly used to grow bacteria, because it is sealed and sterile.
Is there an explanation of why bacteria from one different swabbed object will grow more colonies on a petri dish than another?
It could be the medium in the Petri dish in which the different bacteria grow. It could also be the swabbing technique.
What do fungi and bacteria grow from?
fungi and bacteria grow from spores.
Do Bacteria always live in colonies?
Yeah, they do.
Can I use gelitan in a petri dish to grow samples?
Gelatin medium gives individual bacteria to produce seprate colonies, but despite this gelatin is not an ideal solidifying agent because it can be digested by many bacteria and melt at tempratures above 28oC.
What is used to grow colonies of bacteria away from open air contaminants?
A Petri dish is commonly used to grow bacteria, because it is sealed and sterile.
What are the Advantages for growing bacteria in a broth and on agar plate?
Agar plates gives you a more visual view of the bacteria growth but is limited in the amount of bacteria that can grow on the plate. With broth, you won't be able to see the bacteria colonies but you will be able to grow much more of the bacteria for sampling.
Why does yeast colonies never allow other bacterial colonies to grow around in any media?
The yeast colonies never allow other bacterial colonies to grow around any media because they don't want competition. The yeast colonies never allow other bacteria colonies to grow around any media because they eliminate competition.
Can the streptococcus variety of bacteria grow both hairlike and dotlike colonies?
streptococcus is a strip of sphere like bacteria. They can be found on their own or in long strips
Is there an explanation of why bacteria from one different swabbed object will grow more colonies on a petri dish than another?
It could be the medium in the Petri dish in which the different bacteria grow. It could also be the swabbing technique.
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
Which environment has the most total bacteria either petri dish or liquid agar?
Actually the liquid agar medium is used in the petridishes to grow the colonies of bacteria. The nutritional environment available to the bacteria results in to faster growth of their colonies and also they can be used for the experiments more rapidly
How is extracted breast milk prepared for laboratory testing?
The milk is cultured, allowing colonies of bacteria to grow. The causative bacteria then can be specially prepared for identification under a microscope.
Why are there still some colonies growing in the areas exposed to ultraviolet light?
Some colonies grow under harsh conditions. Certain colonies of bacteria can thrive in areas exposed to a great amount of ultraviolet light.
Larg colonies of bacteria know to exist in?
large colonies of bacteria know to exist in
Where should colonies appear in the case of streak plates?
When using streak plates, the colonies should appear along the streak lines. This is where the bacteria have been introduced and is the first place they will grow.
Does Bacteria grow on fat?
No, bacteria do not grow on fat
