By using pour-plate method with the suitable growth medium.
Wire chambers
Nitrogen gas are normally detected using a Gas Chromatography which can also detect various other gases such as Co2, Co, Nox and so on.
we can check the presence of acidity in tea by using pH paper.
In basic medium using photometric method......
it is where you separate a solid from a liquid using a funnel & filter paper
well, krill cant "smell" things by the human definition using air to smell. however, they can detect odors using water as a medium.
I had to detect the man that was in the car with the lost boy !
In liquid medium one starts by placing one or two loopfuls of the liquid medium directly on the slide. From solid media such as nutrient agar. One starts by placing one or two loopfuls of water on the slide and then using an inoculation loop to disperse the organisms in the water. Bacteria growing on solkid media tend to cling to each other and mus be dispensed suficiently by dilutiion in water.
By using an Oscilloscope
by using compass.
The metabolism of the peptides (as the baterial culture uses them) causes the production of ammonia, which increases the pH.
by using special liquids
The culture on solid media (agar) surface aids microbiologist in identifying microorganism because individual species often from colonies of characteristic size and appearance. When mixed population has been plated properly, it sometimes is possible to identify the desired colony based on its overall appearance and use it to obtain a pure culture. Whereas in liquid broth we get mixed culture and can not identify the seprate colony of any microbial species in that mixed culture.
You can detect alcohol in the body with a blood test. You can also detect alcohol in the body, like police officers, by using a breathalyzer test.
to detect animals using photographing to see
Ice is a type of solid.
That depends on what medium you are using.
