Bacteria DO perform photosynthesis. They are capable of 
utilizing light as an energy source for growth and 
synthesizing its own cellular components from inorganic 
compounds like CO2, H2O, H2S, H2, and nitrate. There are two 
classes: photolithotrophe and photoorganotrophe. The 
cyanobacteria are photolithotrophe. Photolithotrophe bacteria 
utilize H2S or H2 and sunlight for CO2 reduction and produce 
glucose and elemental sulfur. Just my two cents.
