Carbon comes from blackened marshmallow or egg-shells, newspapers which contain cellulose, and sulphur source, for example, calcium sulphate in winogradsky column.
Carbon is important because it promotes the growth of different microorganisms. For example chlorobium, chromatium, rhodomicrobium, and Beggiatoa.
Hydrogen sulphide gradient is generated from bottom to the top in a winogradsky column because they dominate the zone with sulphur which reduces bacteria.
Photosynthesis is different between cyanobacteria and green and purple sulphur which is sulphur anaerobic bacteria being the top layer of aerobic bacteria which produces carbon dioxide which feeds back into the column by creating another reaction.
