No. Agar is a solid at room temperature and would just become solid again. A TSB does not contain agar and therefore can be liquid at room temperature.
E. coli is actually green on tryptic soy agar. The agar itself is a white, amber color.
Use a moistened sterile swab to sample the floor. Put this is tryptic soy broth and incubate for 24 hrs at 32 deg C. Streak the resulting solution on to mannitol soy agar and incubate at 32 deg C until colonies form.
It swarms the whole plate.
you can strain the ingredients and broth with a strainer and take out the solid ingredients.

I'm not sure about Tryptic Soya Agar but where I work we regularly use Tryptic Soya Broths (TSB). All our samples are human tissue samples and they are placed in a small bottle containing the TSB solution. These are then sent for testing. So I imagine Tryptic Soya Agar would be used for similar purposes except of course it would be a solid jelly in a dish and would have to be swabbed with the sample. They're basically just food for any bacteria or fungi that are present.
Oden is a Japanese stew consisting of various ingredients such as daikon radish and fish cakes in a light broth. The stock can be prepared by boiling soy sauce, dashi kombu and bonito flakes.
You can't keep broth from being absorbed by dry ingredients such as pasta or grains (e.g. barley, rice, quinoa, etc.). And frankly, why would you want to? Most other ingredients used to make stock or broth (carrots, onions, celery, meats, etc.) usually give up their moisture to the broth. The best you can do to minimize absorption is to cook the dry ingredients in water in other containers and add them to your broth just before you serve it. The problem with that is that the pasta or grain won't share the broth's flavor. They'll taste "different" than the broth: usually less savory. Another remedy is to add lesser amounts of dry ingredients to where they don't affect the amount of broth as much.
So that you can be sure that the results are due only to one specific species.
Two days at room temperature on TSA (tryptic soy agar)
