Anoxygenic photosynthesis

Anoxygenic photosynthesis is a process used by certain bacteria to convert sunlight into energy without producing oxygen. Unlike plants, which release oxygen as a byproduct of photosynthesis, these bacteria utilize different molecules, such as hydrogen sulfide or organic compounds, instead of water. This method allows them to thrive in environments where sunlight is available but oxygen is limited, such as in muddy sediments or deep water. Anoxygenic photosynthesis plays a crucial role in the ecosystem by contributing to the cycling of elements and supporting diverse microbial communities.
