How could you tell the bacteria were growing in the culture?
Bacteria growing on a petri dish can have more than one bacteria growing on it, but different characteristics can be seen like cilia, motility and color. To know more specifically what those other bacteria strains are, get a sample and grow it on agar by itself.
What can you use besides agar to grow bacteria?
Any type of liquid, even water, will do fine. Although agar is best recommended as it has a lot of nutrients, allowing lots of bacteria to grow. Other liquids work but they don't grow as much and as vigorously.
Why does nutrient broth go cloudy?
Nutrient broth becoming cloudy in appearance is usually a good indication that one or more cultures of bacteria or fungi has grown in the broth. This can be confirmed by viewing a sample of the broth under a simple light microscope, or by streaking a sample onto nutrient agar and incubating it to see if colonies become visible (usually within a few days).
What does agar in the petri dish provide the bacteria with?
A medium (substrate) to grow on and, depending on the agar, nutrients for growth. See link below for more information.
How will the arrangement of thre lactococcus lactis in broth differ from the arrangement in a slant culture?
In the slant culture, the bacterial growth is even to spreading to irregular. On the other hand, in broth culture, the growth ranges from sedimentation at the bottom, to turbid growth to pellicle growth.
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.
Which technique agar or broth provides more information?
Out of the two, nutrient agar will provide more information on the variety of bacteria that are in an environment. Nutrient agar is a better environment for bacteria and fungi to thrive in.

What else grows on an agar plate other than bacteria?
Theoretically, anything. As the agar is a non-selective agar many bugs can grow on nutrient agar. The only ones that can't are ones that have different growing conditions or different characteristics that makes it difficult or impossible to grow, but that is more uncommon.

What is the difference between nutrient broth and nutrient agar and can you elaborate more?
When 2%agar is added to nutrient broth ,it is called nutrient agar.Nutrition Broth is liquid media containing beef extract and peptone.Nutrition Agar is solid media containing beef extract, peptone, and agar

What kind of agar should be used to grow bacteria from hands before and after washing for a grade 8 science fair?
blood or nutrient agar would work, but blood agar will most likely grow more bacteria.

What microorganism grows more slowly in a refrigerator?
bacteria

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
