  1. Great info, but M. tuberculosis is an acid resistant bacterium. The staining picturese shows that, coloring with carbofushin. In the information you have Gram negative. When M. tuberculosis is Gram stained, the reaction is Gram variable.

  2. Thanks for contribution plz my question is that staphylococcus bacteria is used to produce catalase enzymes this mean that the can be used in several aspects more especially in industry
