Is bacillus cereus lactose positive?

No


What are the results for litmus milk test on Bacilus subtilis?

Bacillus subtilis will typically produce an alkaline reaction in litmus milk, turning it pink or purple. This is due to the bacterium's ability to break down lactose and produce ammonia. Additionally, Bacillus subtilis may also cause coagulation of the milk proteins, resulting in a solid clot formation.


Does Morganella Morganii ferment lactose?

no, it shows negative for lactose fermentation on MacConkey's agar


Why does Bacillus cereus ferment Glucose and not Lactose or Sucrose?

Because bacillus cereus is a Gram-positive, spore-forming, and rod-shaped, it\'s only able to ferment glucose.


Give result lactose test for bacteria citrobacter diversus?

Citrobacter diversus is capable of fermenting lactose, therefore it would test positive for lactose fermentation in biochemical tests. This bacterium produces acid and gas during lactose fermentation, which can be detected using appropriate methods such as the MacConkey agar test.


Why lactose does not undergo fermentation process?

Lactose does undergo fermentation when acted upon by lactase-fermenting microbes.


Does proteus mirabilis ferment lactose?

No.----------------------------------------------------------Disagree. You'll find a positive sucrose fermentation test for P. vulgaris at MicrobeLibrary.org. The site is an affiliate of the American Society of Microbiology, so I'm guessing it's a safe bet.


What are the biochemical tests for identification of bacillus subtilis?

The Kirby-Bauer antibiotic test is a general test that determines if an organism is resistant or susceptible to different antibiotics. Many different types of antibiotics can be used but some of the common ones are penicillin, tetracycline, chloramphenicol, and streptomycin.


Lactose fermentation mac conkey test which color indicate a positive test?

MacConkey agar is yellow (due to the lactose in the agar). When an organism consumes the lactose, the agar turns purple. Purple indicates a positive test. If the organism doesn't use the agar, the agar stays yellow.


Result of bacillus subtillis litmus milk test?

If Bacillus subtilis is inoculated into litmus milk, it will likely grow and metabolize lactose, forming acid as a byproduct. This metabolism will cause the litmus milk to turn pink or purple as the pH decreases due to the production of acid. The milk may also show coagulation due to acid production.
