Apart from uid and cyd, what other genes are best for carrying out q-PCR to quantify E. coli from water with minimum coliform bacterial population?
What is the best procedure for sequencing bacteria in phylogenetic analysis. Using isolated plasmid DNA from the bacterial cells and adding omto the primer (27F and 1492R) or just taking the...
