What medium doesn't contain viable microbes?
Sterile environments such as medical-grade clean rooms or sterile laboratories are examples of settings where microbial contamination is controlled to the point that the medium may not contain viable microbes. However, outside of controlled sterile environments, it can be difficult to find a medium that is completely free of viable microbes.
What is the term that refers to the purposeful addition of microorganisms into a laboratory nutrient medium?
Inoculation is the term that refers to the purposeful addition of microorganisms into a laboratory nutrient medium.
Why is a sterile swab used to collect bacteria in the mouth?
because it is important that in nutrient media to grow up only bacteria that may be present in your mouth.In tha case tha swabs are not sterile in nutrient media will growth mouth and swab bacteria and the will give a flas positive result.
How does autotrophic bacteria get food?
They are grown on medium that contains the nutrient that they cannot synthesize
Does Bacillus subtilis grow in MacConkey broth?
Bacillus subtilis is grown on nutrient agar or in nutrient broth. The preferred medium is M9 with glucose.
What is a medium in hydroponics?
The medium is a sterile substrate that takes the place of soil; it provides a place for the plants to grow in as well as a medium through which the nutrient solution can pass. Hydroponics employs a sterile medium, one that does not interact with the plants - perlite, vermiculite, inert stone or rock wool. Hydroponic gardening system that is based on water, not soil. So container is a hydroponic growing medium. There are various types of hydroponic growing mediums like Oasis Cube, Coconut Fiber, Fillers, Ebb and Flow System and aeroponics.

What is nutrient agar?
simply agar medium
What is the term that refers to the purposeful addition of microorganisms into a laboratory nutrient medium?

What is the procedure for growing ecoli in a petri dish?
To grow E. coli in a petri dish, first prepare a nutrient agar medium by mixing agar with a nutrient broth, then autoclave to sterilize. Once cooled to about 50°C, pour the agar into sterile petri dishes and allow it to solidify. Inoculate the agar surface with E. coli using a sterile loop or swab, then incubate the plates upside down at 37°C for 24 hours. After incubation, observe the growth of colonies.
What is rooting medium?
Usually a sterile mix of vermiculite, pearlite, moss, and steralized soil.
What are the equipments used in hydroponics farming?
Hydroponics substitute a nutrient medium in place of soil. for the plants to root and grow. The nutrient medium may be either a water solution or an inert material.
How should a sterile packaged be handled?
Using sterile gloves and making sure it does not touch any non-sterile/contaminated objects
What will result when 1 to 5 agar is added to nutrient broth boiled and cooled?
The agar will solidify and form a gel-like substance in the nutrient broth. This agar-nutrient mixture is used as a solid medium for growing and isolating bacteria in a laboratory setting.
What nutrient medium that has all of its chemical components identified and their precise concentrations known and reproducible would be termed?
Defined medium.
