What else can I help you with?
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 the most common way to grow bacteria is?
The most common way to grow bacteria is in an agar petri dish. The bacteria are usually placed by a swab into the petri dish and incubated for a predetermined period of time (The agar serves as a food source for the bacteria). Then, growth, or no growth, of bacteria will be observed.
What do fungi and bacteria grow from?
fungi and bacteria grow from spores.
Why bacteria is grow in labortary if its ubiquitous in nature?
Bacteria can grow in the laboratory because the conditions provided are optimal for their growth, such as a nutrient-rich environment, suitable temperature, and pH levels. In nature, bacteria may face competing organisms or adverse conditions that limit their growth, whereas in the laboratory, these limiting factors are controlled or removed.
What is the purpose for pour plate?
The purpose of a pour plate is to determine the concentration of bacteria in a sample by counting the number of colonies that grow on the agar plate after incubation. This method allows for both surface and subsurface colonies to be counted, providing a more accurate representation of the bacterial population in the sample.
Can bacteria grow in distilled water?
Yes, bacteria can grow in distilled water if it is exposed to contaminants or nutrients that support their growth. Distilled water itself does not contain nutrients for bacteria to thrive, but if it comes into contact with substances that provide nutrients, bacteria can grow in it.
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
How do you decide which colonies should be picked from a plate culture of mixed flora?
To decide on which colonies you should pick from a plate culture, you'll have to know whether you desire to grow a mixed culture of different microbes and bacteria or a pure culture that consists of only one strain of bacteria or microbe.
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
How do you identify a contamination on a pour plate?
Contaminants on a pour plate may appear as additional colonies that are morphologically different from the intended microbial culture. Contaminants can also show different colors, textures, or sizes compared to the colonies of the desired organism. Additionally, contaminants may grow in areas where there should be no growth on the agar plate.
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.
How Cultivation of bacteria?
To cultivate bacteria, you would typically streak a sample onto a nutrient agar plate in a sterile environment. The plate is then incubated at the optimal temperature for the specific bacteria species to grow. After incubation, colonies of bacteria will form, which can be studied and analyzed.
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
