Want this question answered?
tube coagulase is done in test tube while slide coagulase is done on slide.thnk you all! cheeres!
YES
Rabbit plasma, sometimes with EDTA added
staph. aureus test positive for catalase test and coagulase test consecutively
No, Catalase +ve, Coagulase +ve, Gram + cocci. Citrate test is usually used to differentiate members of the Family Enterobacteriaceae. Check Bergeys systematic bacteriology. 1980
it turns to rainbow colour....sucka
It is NEGATIVE

Coagulase is a protein enzyme. It is important to use fresh cultures in a coagulase test because coagulase expression is highest during the log phase of growth.
YES
H2S (hydrogen sulfide) Test: This test is used to check for Enteric gram negative bacilli by checking for the enzyme thiosulfate reductase which is produced by various intestinal microorganisms. So if bacillus subtilis can produce this enzyme then this test will give you a pos. (black in color) result. Yeah, no kidding. I'm pretty sure the question was what the result of it, or they wouldn't specify that it was b. subtilis. and it is positive for H2S production.
No, it is negative.B. subtilis on EMB agar:http://www.microbelibrary.org/microbelibrary/files/ccImages/Articleimages/Atlas_EMB/Bacillus-subtilis_EMB_fig11.jpg
