Consider the following microorganisms:
- **Bacterium A**: A Gram-positive, spore-forming rod that is strictly aerobic, thermophilic, acidophilic, and
resistant to streptomycin. It ferments glucose but not lactose.
**Bacterium B**: A Gram-negative rod that is a facultative anaerobe, mesophilic, neutrophilic, and resistant
to ampicillin and tetracycline. It ferments lactose and sucrose.
**Bacterium C**: A Gram-positive coccus that is strictly anaerobic, psychrophilic, acidophilic, and resistant
to erythromycin and chloramphenicol. It does not ferment carbohydrates.
**Bacterium D**: A Gram-positive rod, facultative anaerobe, mesophilic, neutrophilic, halophilic, resistant
to streptomycin and ampicillin. It ferments glucose, lactose, and mannitol.
**Bacterium E**: A Gram-positive coccus, facultative anaerobic, mesophilic, halotolerant, resistant to
chloramphenicol, and ferments mannitol.
**Bacterium F**: A Gram-negative rod, strictly aerobic, mesophilic, resistant to chloramphenicol and
tetracycline. It does not ferment carbohydrates.
If this mixture of bacteria is inoculated into mannitol salt agar supplemented with chloramphenicol and
incubated at 37Ā°C under anaerobic conditions, which of these bacteria will be able to grow?
