What will happen if the correct concentration of agar is not used?
If the correct concentration of agar is not used, it may lead to inconsistencies in the solidification of the agar, affecting the growth of microorganisms or the results of experiments. Too much agar can make it difficult for organisms to grow, while too little agar can result in a weak gel structure that doesn't hold up well over time.
Why the inoculated agar medium plate must be inverted position in incubator?
Moisture in the air condenses on the lid of the plate and drops on top the agar if the plates are place right way up. The falling water droplets will spread the bacteria and especially ruin streak plates and spead plates where you need clear distict separate colonies.
Is Agar a homopolysaccaride or heteropolysaccaride?
Agar is a heteropolysaccharide composed of agarose and agaropectin. Agarose makes up the majority of agar and consists of repeating units of agarobiose, while agaropectin is a minor component with a more complex structure.
What is the concentration of bacteriological agar normally used in making solid media?
Agar is added in a concentration of 1.5% to solidify liquid media. Although there are different concentrations of agar used to create different conditions such as in Sabouraud's Agar and semisolid agar.
How do you pick up a reagent bottle?
To pick up a reagent bottle, ensure your hands are clean and dry. Grasp the bottle around its body or neck, being careful not to touch the lid or the inside of the bottle to maintain the purity of the reagent inside. Lift the bottle carefully to prevent spills or breakage.
Why shouldn't you dig into agar with the loop?
Streaking is to produce single colonies. If we are digging to the agar while streaking the microbes, instead of growing on the agar surface grows in the subsurface as well. These colonies may be difficult to isolate.
How do you throw a pie?
Pick it up with care, then find the enemy and chuck it. Then make a new one, but be careful!
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.
Why MacConkey agar is solid at room temperature while MacConkey broth remains Liquid at room Temperature?
MacConkey agar contains agar as a solidifying agent which solidifies at room temperature to provide a solid surface for bacterial growth and colony isolation. MacConkey broth, on the other hand, does not contain agar and remains liquid at room temperature to allow for easier culture of bacteria in liquid medium for metabolic studies or growth analyses.
Why colony represent a pure culture?
The colony started from one single microbe that divided and divided until it formed what we call a colony of all the same bacteria. By selecting that colony we can be sure that its is pure and will grow only into a pure culture. Be sure to select on that is isolated so that you will not pick up a contaminate.
What do you do if your dog as yellow slimy poo?
first of all pick it up like normal but be careful it's hard to pick up. Then book it a vets appointment and see what they say hi. It's possible to be diarrhea.
Does an x-ray pick up a hairline fracutre?

By selecting that colony we can be sure that its is pure and will grow only into a pure culture. Be sure to select on that is isolated so that you will not pick up a contaminate.
How do you take care of a new born guinea pig?
first, don't pick it up for at least a week. this might stress the mother out and then she might kill the baby. then care for it the way you would care for an adult. but when you pick it up, just be a bit careful not to hurit it.
