It is important to characterise different strains of particular species for the benefit of microbiologists and scientists.
IT is necessary so that scientists can discuss about the species without mentioning the characteristics.
They are characterised on basis of biochemical and other phenotypic criteria and by DNA relatedness(on basis of genetic similarity).
Within same speicies the strains differ by the types of diseases the cause, what is there environmental habitat and many other physiological characters so strains are grouped on basis of large number of phenotypic characters.
For example while grouping of stains microbiologists are interested in serotype, antimicrobial resistance pattern, and toxin and invasiveness factors in Escherichia coli, whereas geneticists are concerned with specific mutations and plasmids.
So in all it is an easy way for microbiologists to communicate among themselves using different strains.

Consider an LB broth flask into which two E. coli strains are inoculated. Strain "A" is wild-type, with g = 22 min at 37oC, and 45 min at 27oC. Strain "B" has a temperature-sensitive mutation, such that g = 52 min at 37oC, but at 27oC g = 44 min.We inoculate equal amounts of cells (1 ml of each starter culture whose population is 1 x 106 cfu/ml) into each of two separate 1 liter volumes of LB broth at...

· In one experiment Lederberg used Gal+ and Gal– strains of E. coli. One half of a plate that contained medium with galactose as the only carbon source was inoculated with phages that came from lysed cells of the Gal+ strain. The other half of the plate was left uninoculated. A Gal- strain was then placed on the entire plate. Numerous colonies appeared on the half of the plate inoculated with the phage, whereas only a few appeared on the...

Operon. A particular E. Coli strain has a mutation in the operator of the tryptophan operon. How would you expect it would affect the functioning of the operon and the metabolism of the cells? What would happen if the trp operon had a mutation in the: 1. Promoter region? 2. Repressor gene (domain binding to tryptophan)? 3. Leader sequence TGGTGG? 4. Region 3 of Leader mRNA?

Replication of the E. coli chromosome starts at a particular point, the origin of chromosomal replication (oriC) and proceeds bidirectionally around the circular chromosome. A. Describe how the strands at oriC are separated to allow replication of the chromosome. B. Once the replication is initiated the process of bidirectional semi-discontinuous DNA replication occurs. Describe this process.
