Answer:
See the answer below
Explanation:
<em>Obligate anaerobes are microbes that can only survive in oxygen-deficient environments. They are killed by the normal atmospheric level of oxygen and will only thrive in environments whose oxygen levels are lower than that of normal atmospheric level. </em>
Obligate bacteria such as <em>Clostridium botulinum </em>obtain their energy through <u>anaerobic respiration processes such as fermentation and anaerobic respiration.</u> During this process of fermentation, the lactic acid pathway is mostly used but other fermentation pathways such as propionic acid, mixed acid, acetogenesis, and methanogenesis pathways can be used.
That answer would be hypothesis
