A

B
Staphylococcus
C
Sporosarcina
D
Clostridium
Verified step by step guidance1
Understand what endospores are: Endospores are highly resistant, dormant structures formed by certain bacteria to survive harsh environmental conditions.
Recall which bacterial genera are known for endospore formation: Typically, endospore formation is characteristic of genera such as Bacillus and Clostridium, which are both Gram-positive rods.
Consider the genus Sporosarcina: This genus is also known to produce endospores, similar to Bacillus and Clostridium.
Analyze the genus Staphylococcus: Staphylococcus species are Gram-positive cocci and are not known to produce endospores; they survive harsh conditions by other mechanisms.
Conclude that among the options, Staphylococcus is the genus that does NOT produce endospores.
