Question

discuss in detail methods used for measurement of bacterial growth ​

Answer 1

Answer:

There are many ways to measure bacteria growth, and some are more complex than others. Though you sacrifice some consistency in your measurements, the simplest methods are accurate enough and used commonly. The most well-known methods are observing and counting the bacteria, measuring wet or dry mass, and measuring turbidity. Your school’s lab should have the equipment and supplies to conduct at least one of these experiments

Gather your materials. There are a few special tools you should have in addition to what is stocked in most biology labs. Having your instruments and containers ahead of time will allow you to complete the experiment without having to run back and forth to the cabinet. It is important to know what each piece will be used for up front. You should know some basic terms as well.

Get a counting chamber. These tools have a chamber, slide, and microscope built in, so they are easy to set up and use. You can buy them from lab and classroom supply companies. They come with instructions that guide you through the whole process. [2]

Get a pour plate or a spread plate. These are the containers you will observe the bacteria in.

Culture is the term used to describe an organism grown artificially for an experiment.

Broth is a liquid medium that the culture grows in.

Use your pour plate or spread plate. You can also place the bacteria directly onto a plate for viewing under a microscope. Apply the culture to the plate and place under a microscope. Observe how many bacteria cells there are.
