One study researching alternative methods for urinalysis found that urea levels could be detected using electrochemical signaling from redox reactions that take place on the surface membrane, specifically the conversion of urea to ammonia (8). The bacterium was added to the citrate and left to incubate for 48 hours, results showed a negative result. This complex is a larger molecule than the original crystal violet stain and iodine and is insoluble in water. Being a non-fermentor, the bacterium is also associated with acid production in culture rather than gases which are commonly associated with fermenting bacteria. Decolorization Solution: Add 30 mL hydrochloric acid to 1 L of 95% denatured alcohol. There are two methods of acid-fast staining. Gram-positive coccal bacterium that is a member of the Firmicutes, and is frequently found in the human respiratory tract and on the skin. A direct correlation between the ammonia oxidation peaks and the urea concentrations in the synthetic urine were shown (8). More often, women present with UTI, flank pain, or hematuria, and are found to have a persistently alkaline urine pH (>7.0). Biochemical Test and Identification of Citrobacter freundii.
