What is the difference between bacillus and clostridium?
Bacillus and Clostridium are both Gram positive, spore forming, bacilli (rods).Bacillus sp. are aerobic.Clostridium sp. are anaerobic.After performing a catalase activity test, Clostridium will be negative and Bacillus will be positive for catalase activity.

What is the hydrogen sulfide test used on Bacillus subtilis?
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.

What is alppha hemolytic?
Alpha hemolysis (α-hemolysis) means that the bacterial enzymes only partially break down the blood cells. This results in the media showing a yellowish/greenish/brownish discoloration (like a bruise) around the colonies, indicating incomplete hemolysis.How to Interpret Beta Hemolysis on Blood Agar: Test for Strep Throat - Identifying B-hemolytic Streptococcus

Differentiating between bacillus cereus and clostridium sporogenes?
The easiest way to distinguish one from the other is by performing an amylase test. Bacillus cereus will test positive by displaying a clear zone around the bacteria. Clostridium sporogenes will test negative because it does not produce the exoenzyme amylase. Another way is by performing a catalase test. Bacillus will test positive because it's an aerobe and Clostridium will test negative because it's anaerobic.
