Biochemical Test of Listeria monocytogenes
About Author
Durham fermentation tubes for glucose, lactose and sucrose?
Citrate test is not listed. Positive or Negative?
In one of the research papers, the citrate test was NEGATIVE (-ve). Paper Link-https://www.ijcmas.com/Archives/vol-2/PDF/R.Vinothkumar%20et%20al.pdf
My rating was 3/5!
The details were scanty for beginners.
But it’s okay with professionals.
Though, there’s need to carry everyone along. So you can choose a midway between the two.
