photoautotrophy मीनिंग इन हिंदी

This mechanism of photoautotrophy usually uses hydrogen sulfide ( H 2 S ) as an electron donor and a single photosystem as a catalyst, oxidizing sulfide to sulfur and sulfate to support the growth of phototrophs in anoxic sulfidic environments exposed to light, such as laminated microbial mats and pycnoclines of stratified lakes.
