  1. Id like to note that some of these are incorrect. Bergy’s manual specifically states the fact that it is positive for gelatin hydrolysis as well as a positive methyl red test and a negative VP test.

  2. If you see -ve in the table it means negative and +ve it serves as positive so it means a sign of reaction
