Why we do not use jelly instead of agar as a medium for the growth of bacteria?

Jelly - solid or liq: Microbiologists want their bacteria to be on a well-defined, predictable, relatively pure media, so that everyone agrees on the resulting growth pattern, shape, color, etc. Preference is given to solid media (agar plates) or liquid media (broth).

How long can I use the same water bottle before washing or acumulating harmful bacteria?

How long can I use the same water bottle before washing or acumulating harmful bacteria?

Wash it twice a week: A healthy person using a water bottle to carry clean drinking water is unlikely to get an illness from "harmful" bacteria in the bottle. Neither the water nor the bottle are sterile, so there will be some bacteria, but probably won't cause disease. Rinsing the bottle with a little drinking water at each refill will help keep the bottle clean. Actual cleaning of the bottle can be done twice a week. ...Read more

The CDC recognizes UV light as an effective way to disinfect small quantities of clear water. Any particles in the water (however small) could block the UV light and protect the germs. Boiling and iodine are older technologies that work. ...Read more
