Overview

This study demonstrates active carbon fixation rates in mangrove sediments, implying diverse microbial mechanisms at play.

Key Points

  • Active carbon fixation rates ranged from 0.02 to 3.27 mmol C m −2 day −1 across sediment depths.
  • Six distinct carbon-fixing pathways were identified, with the CBB cycle and WL pathway being predominant.
  • Metagenomic and metatranscriptomic analyses showed microbial activity linked to environmental factors in mangrove sediments.
  • Methane-producing archaea, such as Methanosarcinia, were vital in driving carbon fixation in deeper sediment layers.
