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.
