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.
The broth is cloudy and there is usually sediment on the bottom and top of the broth in the container.
the bacteria can product colony in agar culture or opaque in broth culture
We can detect growth in a broth culture by observing turbidity. The turbidity can be detected by an instrument called calorimeter.
If bateria growson an agar plate it means that the thing that touched the LB Agar or what you swabed was contaminated.
you have to watch the bacteria for a few days but make sure you measure the bacteria each time you check it
You'll be able to see it, if it grows.
The bacteria's oxygen requirements
why is turbidity not an accurate measurement of viable bacteria in a culture
we could tell by our height because if your height grows your bones are still growing i know this because our bones need calcium to grow and that's how we grow
You don't have to even check. Everything on the planet is covered in bacteria. It may be growing, or just waiting for the right conditions for it to multiply. And even before you see anything like changes in color or oder, they have already multiplied into the thousands, and even millions. Unless it was just sterilized in a autoclave oven at the right temperature for the correct length of time, it already has bacteria that only time and available food supply that keep them from growing into what you can see or smell, but just remember, they are already everywhere. Technically, the only way to tell is by visual examination, and the only way to do that is with a microscope.
The purity of a culture of bacteria is important so it can test on that one type of bacteria. Gram staining can be good so you make sure everything in the streak plate is one color showing that it is gram positive and gram negative.
Please tell us answer
why is turbidity not an accurate measurement of viable bacteria in a culture
by growing on suitable media.
the only way to tell is to do the experiment multiple times and compare the results. also using a control group. an outlier in the results can be from contamination and be an error in the experiment.
A sputum culture will generally tell. Bacteria can be cultured, viruses can't.

What does a language's vocabulary tell about its culture?

its way to much to tell there is countless amouts of bacteria and it would be imposable to tell you.
You will see different color colonies, irregular ones, or round and even ones on a streak plate.

the photogenic bacteria have the size of spherical have a length of 2-4 x
