Purple bacteria photosynthesis
WebFeb 27, 2015 · Green sulfur bacteria are strict anaerobes that are capable of photosynthesis. Green sulfur bacteria absorb longer wavelengths of light than purple sulfate bacteria. … WebGreen algae are aerobic and oxygenic, whereas purple bacteria are primarily anaerobic and anoxygenic . Moreover, green algae and purple bacteria absorb distinct wavebands because of the different photosynthetic pigments [e.g., the absorption peak of chlorophyll a is at ~600 to 700 nm and those of bacteriochlorophyll a at ~800 to 900 nm; (13, 14)].
