Luria agar is Luria broth with the addition of 15 grams per liter agar. Agar is a solidifying agent that makes the liquid media solid at room temperature. Hence, luria agar would be a petri dish of agar while luria broth would be liquid to go in a tube or flask.

∙ 9y agoNutrient agar will grow the largest number of different types of microbes, fungi and bacteria, however some bacteria will not grow on this. A subtype of nutrient agar, luria bertani is a general medium and may be used for cultivation of microorganisms that are not fastidious.

∙ 15y agoThe primary difference is the state in which the nutrient is in. Nutrient broth's tend to be liquid, while agar plates tend to be solid. Although both can be composed of any number of nutrients depending on the wanted bacterial growth, the fact that broths are liquid and agar is solid manifest as different pros and cons when culturing bacteria. For example, agar plated cultures grow as flat cultures, favoring say animal epithelial cells which normally grow on a flat surface to which they attach, while bacteria grown in liquid cultures often form colloidal suspensions.
While bacteria such as Escherichia coli may be grown on solid media or in liquid media, many cells types prefer a particular medium. Additionally the ultimate use for the culture may determine whether one of the culture types is most appropriate (for example counting colonies will best be done on an agar plate).

What is the procedural difference between using broth and agar as a source of bacteria for preparing a smear?
If your colonies were grown in broth, you can simply use your loop to collect loopfuls of liquid medium and smear that onto a glass slide. If they were grown on an agar plate you would have to add a few drops of water to the surface of the glass slide.
Which grows more bacteria broth or agar?
Agar, because broth is a natural fuel source for bacteria, whilst some types of agar are scientifically created, which makes it supreme for growing bacteria.
What is slant broth and deep?

Why MacConkey agar is solid at room temperature while MacConkey broth remains Liquid at room Temperature?
MacConkey agar is solid at room temperature because it is a gel-like polysaccharide. Broth that has 1.5 percent agar in it and is heated up will become a liquid.
What is the composition of luria agar?
The composition of luria agar is NaCl,Trypotone, Yeast extract and agar.
What does LB stand for in LB agar?
LB stands for Luria Bertani. It is a growth medium used for most of the bacterial cultures, compositions of LB broth is 10g of tryptone, 5g of yeast extract and 10g of NaCl. For LB medium add 75g/l of Bacteriological buffer in the broth and pour it in the plate to solidify,.
Is broth has agar?
no, broth stands for liquid and agar is used as solidifying agent so broth is not containig agar.
