Gram-positive bacteria are bacteria that have thick cell walls which yield positive results in the Gram staining test. Lipoteichoic acid is a major component of the cell wall of gram-positive bacteria.
- All bacteria indicated in the question can be classified by the Gram staining test:
- Actinomycetes are Gram-positive bacteria
- The genus <em>Arthrobacter </em>includes Gram-positive bacteria
- <em>Escherichia coli </em>(<em>E. coli</em>) is a Gram-negative bacterium
- <em>Staphylococcus spp.</em> are Gram-positive bacteria
- <em>Bacillus spp</em> are Gram-positive bacteria
- <em>Mycobacterium spp.</em> are Gram-positive bacteria
- Prokaryotes can be divided into two domains: Bacteria and Archaea.
- Gram staining is a method used to classify bacteria, but this method IS NOT USED to stain Archaea.
- In consequence, I would not use the Gram test to stain Archaebacteria because Archaebacteria aren't bacteria (Option A is correct).
- Archaebacteria belong to the Archaea domain.
