Table 1 The reason of using RNA-SIP and DNA-SIP for studying ANME-1 and Bathy-8, respectively
SIP | Sensitivity | Downstream metagenomics | MAG availability | Archaeal group |
|---|---|---|---|---|
RNA-SIP | High | MAGs cannot be retrieved from RNA | Yes | ANME-1 |
DNA-SIP | Relatively low | Possible to retrieve MAGs from the DNA-SIP heavy fractions | No (Bathy-8 MAG was not retrieved from sediment) | Bathy-8 |
