Citrate Test Negative Bacteria List. Web 24 hour cultures of citrate positive species (klebsiella, enterobacter, proteus, serratia, pseudomonas, or salmonella) and citrate negative species. Web imvic series contains the following biochemical tests:
No growth and no color change. Enterobacter species (minority of strains gives negative result) citrobacter. Some citrate negative organisms may grow weakly on the surface of the slant, but they will not produce a color.
Web Bacterial Species That Are Capable Of Metabolizing Citrate Are Considered Citrate Positive And Will Cause Simmons' Citrate Agar To Change From Green To Blue.
Variable (different strains give different results) proteus vulgaris; Principle of citrate utilization test a citrate utilization test. Web 24 hour cultures of citrate positive species (klebsiella, enterobacter, proteus, serratia, pseudomonas, or salmonella) and citrate negative species.
