Question

identification of microbes​

Answer 1

Answer:

Among the techniques we use are: DNA sequencing – to identify bacteria, moulds and yeasts. Riboprinter analysis – for bacterial identification and characterisation. Repeat–based polymerase chain reaction – for assessing the similarity of microorganisms.

Explanation:

Traditional methods for microbial identification rely on phenotypic identification using staining, culturing and simple biochemical tests. Nowadays, newer and more powerful molecular, immunological, and biochemical analytical methods complement and sometimes replace traditional methods.

Answer 2

Explanation:

Identification of microorganisms – provides the name of the organism (to genus or species level), which can help in determining whether it is a safety or spoilage concern or is likely to be heat resistant, for example.

Sometimes, however, you need to know more - including where a contaminant came from. Many organisms occupy a diverse range of habitats, and so the only way of knowing the origins of a particular contaminant is to identify/characterise it to a specific strain and then match that with a strain elsewhere in the environment or in a particular food ingredient.
