| Abstract: | Stable isotope probing of magnetic-bead-captured rRNA (Mag-SIP) indicated clear differences in in situ organic substrate utilization by major microbial groups between the more oxidized (0 to 2 cm) and sulfate-reducing (2 to 5 cm) horizons of marine intertidal sediment. We also showed that cyanobacteria and diatoms may survive by glucose utilization under dark anoxic conditions. |
