In this study, the cbb genes which encode the key enzymes in the Calvin cycle were used as functional markers to investigate the distribution pattern of CO2 fixing potential of autotrophic bacteria at different depths of the South China Sea (SCS). The results revealed that cbb gene abundance was similar between the surface and the deep layer of SCS, over two fold higher than the middle layer. The types of cbb genes showed dramatically different distributions with depths. Metagenomic amplicon sequencing revealed that Synechococcus was the main genus containing cbb genes in the surface layer, along with Rubrivivax and Limnohabitans in the middle, and unclassified Epsilonproteobacteria in the deep. Furthermore, the surface layer had the highest CO2 fixing potential due to that Synechococcus had a high CO2 fixation capacity and relatively high autotrophic growth rate. The difference in the distribution of bacterial species and therefore cbb types with depths was potentially affected by the variation in light intensity and concentration of dissolved oxygen, inorganic carbon and reducing substances.

Geologic Data

The distribution pattern of early Telychian (turriculatus–crispus graptolite biozone) red beds in the Eastern Yangtze Platform of South China is reconstructed based on regional geologic data. The red beds are developed in three areas, which are separated by regions without red deposition. The distribution pattern indicates that the Cathaysian Oldland was the provenance of sediment rich in ferric oxides, which are essential for the formation of red beds. Silurian marine siliciclastic red beds, both in China and worldwide, tended to develop during times of relatively low sea level. Coeval hematitic oolites that formed far from the coast may record a change from reducing to oxidizing conditions in the ocean. Furthermore, it is likely that a fall in global sea level, a transition from reducing to oxidizing conditions in the ocean, and a cooling climate, all of which were closely related to the early Telychian Valgu Event, promoted the global development of marine red beds during this period.
