Carbon-fixing bacteria and sediment organic carbon response to the introduction of mangrove plant Sonneratia caseolaris (opens in new tab)

The fast-growing Sonneratia caseolaris has been widely used in restoration efforts to accelerate the recovery of degraded mangrove ecosystems. Carbon-fixing bacteria (CFB) are recognized as major microbial contributors to sediment carbon accumulation in the mangrove wetlands. However, the response of the CFB community and sediment organic carbon (SOC) to introduced S. caseolaris is still unknown. In this study, the sediment properties (especially SOC), the abundances of carbon-fixing genes (c...
