/ɡriːn ˈsʌlfər ˈbæktəriəm/

Meaning and Usage

"Green sulfur bacterium" refers to a group of photosynthetic bacteria that are characterized by their green pigmentation. These bacteria perform photosynthesis using light energy, and they are found in various environments, particularly in anoxic conditions such as hot springs, and in the sediments of lakes and marshes. They play a crucial role in the sulfur cycle as they utilize sulfide as electron donors.

The phrase "green sulfur bacterium" is relatively specialized and primarily occurs in written contexts, particularly in scientific literature, due to its specific relevance in microbiology and environmental science. This term is not commonly used in everyday conversations.
