Viruses in marine sediments: a review of their effect on biogeochemistry and microbial interactions | Applied and Environmental Microbiology In the ocean, viruses are known to mediate the carbon cycle, keeping dissolved organic carbon (DOC) in the microbial loop and preventing its movement into secondary consumers (1). However, few direct measurements of this carbon flux exist, and recent considerations of the ocean system consider that viruses can not only loop carbon in the dissolved pool but also participate in a carbon shuttle through the creation of aggregates that pellet or can be part of a viral vent that releases carbon into the atmosphere (2). While the pelagic ocean has been well reviewed for viral contributions to microbial diversity and biogeochemical cycling, less attention has been paid in recent years to the sedimentary portion of the ocean, where carbon is potentially stored over geological time, but viral influence can still be felt. Here, we review the literature on viruses in sedimentary ecosystems and their potential role in biogeochemistry and microbial diversity.

Dehalogenimonas Strain W from Estuarine Sediments Dechlorinates 1,2-Dichloroethane under Elevated Salinity Organohalide-respiring bacteria (OHRB) have been found in various environments and play an indispensable role in the biogeochemical cycling and detoxification of halogenated organic compounds (HOCs). Currently, few ORHB have been reported to perform reductive dechlorination under high salinity conditions, indicating a knowledge gap on the diversity of OHRB and the survival strategy of OHRB in saline environments (e.g., estuarine, marine). This study reports the characterization of an enrichment culture dominated by a new Dehalogenimonas population strain W derived from estuarine sediments, which demonstrates the capability to dechlorinate 1,2-dichloroethane (1,2-DCA) to ethene under elevated salinity (≥5.1% NaCl, w/v). Metagenomic and proteomic analyses revealed that the distinctive high-salinity dechlorination of strain W is primarily attributed to a putative reductive dehalogenase (RDase) DdeA, which shares >91.4% amino acid identity with the dihaloeliminating RDase DcpA from other Dehalogenimonas strains. Additionally, ectoine biosynthesis enzymes (EctABC) contribute to the strain’s salt tolerance. These findings underscore the potential of OHRB, particularly Dehalogenimonas, to detoxify HOCs in high-salinity environments, such as estuarine and marine ecosystems, by employing compatible solutes as an adaptive mechanism.
