What is it called when feces are placed in a growth medium for bacterial analysis?
stool culture
What is the function of media agar?
Agar, which is a polysaccharide polymer, is a solidifying agent for culture medium. It also provides a solid surface for bacterial growth.
Which of these algae are used to prepare a medium for bacterial culture?
Red Algae ?
Why is culture medium cooled 48 temperature before is poured?
In pour plate technique the culture to be grwon is pour in melted agar medium, now when we add the diluted sample in agar plate and if the melted agar is very hot, it can lead to the damage of bacterial or fungal cell and may cause in abruption of growth, so the agar is cooled to get the optimum temp. for growth of microbial cell.
What type of culture medium would increase the size of a bacterial capsule?
it depends on the bacterial capsule, some grows on glucose, some grow on carbondioxide and low iron(LIM culture).

What is bacterial suspension?
Refers to the bacteria suspended on the petri dish or growth medium.

What information is gained from bacterial culture?
Many things can be found by using bacterial culture: Is this a bacterium in the first place. In what form does it show on a streak plate. Does it grow in air or not or both. Does it grow on everyday medium (nutrient agar) or does it need special medium (fastidious). What color is it on the medium. Is it sensitive to various antibiotics.
Why is ground beef a better bacterial growth medium than steak or roast?
The bacteria would be grounded up with the beef and it would be spread throughout the meat, making it ideal for the media to have bacterial growth throughout. Unlike the steak or roast where it would only have bacterial growth on the surface.
How can you determine whether a bacterium is lipolytic?
When lipids are added to an agar-solidified culture medium and are cultured with lipolytic bacteria, the surrounding medium becomes acidic due to the release of fatty acids. By adding a pH indicator (such as Spirit Blue which has a lavender color), it is possible to detect lipolysis by a clear area surrounding the bacterial growth. A clear area around bacterial growth indicates a positive test. In the absense of lipolysis, the medium retains its lavender color and is a negative reaction.
Why is milk such a good culture medium?
milk contains calcium,fats,proteins,all of which are required for bacterial growth.this is why milk is a good culture...
What algae is used to prepare a medium for bacterial culture?
Gracilaria algae used for prepare agar agar powder and it act as solidify agent in medium.
How do you grow aerobic culture?
* We all know that Aerobic means in presence of air. * when a culture medium is kept outside in presence of air to grow is considered as growth in aerobic medium. * Simply it can be called as the growth of culture media in invibo condition but not in invitro condition.
