Question

how can mycoplasma survive without oxygen in brief?​

Answer 1

Answer:

Absence of cell wall in mycoplasmas makes them penicillin resistant. Option B is correct. They are facultative anaerobes which allow them to carry out aerobic respiration in presence of oxygen and anaerobic respiration in its absence, i.e., they can survive without oxygen.

Answer 2

Answer:

Without a cell wall, pathogenic species in this genus are unaffected by many antibiotics such as penicillin or other beta-lactam antibiotics that target cell wall synthesis. Mycoplasma are the smallest bacterial cells yet discovered, can survive without oxygen and are typically about 0.1 μm in diameter.
