Summary Introduction
To write:
The advantage and disadvantage of the multiple tube technique in detecting the coilforms.
Introduction:
Multiple-tube method is a method that is useful to identify and specify the total number of coliforms in a water sample. In this method, a sequence of tubes contains an appropriate selective broth culture medium. This media is inoculated with the test portions of a water sample.

They are hydrophobic, and they insert into the membranes to create pores.arrow_forwardFor the juice samples in exercise 3-4, you will be using the pour plate technique. In this exercise, you will add juice to a petri dish and pour agar over the sample and mix. Why is the media (potato dextrose agar, PDA) kept in a water bath until you are ready to use it, and why must you work fairly quickly? (One response answers both questions). The media is already solid and will form chunks The media has a dye added to it that must be kept at 45°C until ready to use O PDA is a media that allows growth of many types of fungi, and the heat from the water bath keeps the fungal spores from growing. The media is kept liquid in the water bath with heat, removing the tube from the heat source will cause the PDA to solidifyarrow_forward
