One important lineage of marine bacteria is the Roseobacter group. Members of this clade are the most abundant bacteria in marine ecosystems constituting up to 25% of the marine bacterioplankton. They have been detected in various marine habitats from coastal regions to deep-sea sediments and from polar regions to tropical latitudes. These bacteria are physiologically and genetically very versatile. Utilization of several organic and inorganic compounds, sulfur oxidation, aerobic anoxygenic photosynthesis, carbon monoxide oxidation, DMSP demethylation, and production of secondary metabolites are some of the important functional traits found in this clade. Moreover, several isolates are available allowing in-depth analysis of physiological and genetic characteristics. Although the Roseobacter group has been intensively studied in recent years, our understanding of its ecological contributions and the evolutionary processes shaping the genomes of this clade is still rather limited."],["dc.identifier.doi","10.3389/978-2-88945-538-6"],["dc.identifier.isbn","978-2-88945-538-6"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/63325"],["dc.language.iso","en"],["dc.publisher","Frontiers Media SA"],["dc.title","Molecular ecology and genetic diversity of the Roseobacter clade"],["dc.type","book"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]

Molecular analysis indicated an increasing diversity between communities of the Roseobacter group from the sea surface to the seafloor and revealed distinct compositions of free-living and attached fractions. Culture media containing dimethyl sulfide (DMS), dimethyl sulfonium propionate (DMSP) or dimethyl sulfoxide (DMSO) stimulated growth of roseobacters showing highest most probable numbers (MPN) in DMSO-containing dilutions of surface sediments (2.1 x 10(7) roseobacters cm(-3)). Twenty roseobacters (12 from sediments) were isolated from DMSP-and DMS-containing cultures. Sequences of the isolates represented 0.04% of all Bacteria and 4.7% of all roseobacters in the pyrosequencing dataset from sediments. Growth experiments with the isolate Shimia sp.

However, CARD-FISH and amplicon sequencing methods have not yet been directly compared to assess the composition of bacterioplankton communities. Therefore, these approaches were used to study the composition of bacterial communities in two North Sea seawater mesocosm experiments supplemented with diatom-derived organic matter (OM). All approaches revealed Proteobacteria and Bacteroidetes as major components of the bacterioplankton communities. The Roseobacter group and its RCA cluster, as well as Bacteroidetes and Gammaproteobacteria, responded most strongly to OM addition, whereas the SAR11 clade responded in only one of the two mesocosms. A correlation analysis showed that CARD-FISH and amplicon sequencing data of the SAR11 clade and the Roseobacter group, together with its RCA cluster, were highly significantly correlated, whereas Bacteroidetes did not yield any significant correlation and Gammaproteobacteria was only correlated with the potentially active fraction. However, subgroups of these phylogenetic groups, the SAR92 clade, the genera Pseudoalteromonas and Polaribacter, exhibited significant correlations in one of the two mesocosms. Correlations of CARD-FISH with amplicon sequencing data from the total and potentially active fractions of these lineages exhibited distinct differences.

Recent studies assessed microbial taxonomic and functional biogeography in global oceans but microbial functional biogeography remains poorly studied. Here we show that in the near-surface Atlantic and Southern Ocean between 62°S and 47°N microbial communities exhibit distinct taxonomic and functional adaptations to regional environmental conditions. Richness and diversity showed maxima around 40° latitude and intermediate temperatures, especially in functional genes (KEGG-orthologues, KOs) and gene profiles. A cluster analysis yielded three clusters of KOs but five clusters of genes differing in the abundance of genes involved in nutrient and energy acquisition. Gene profiles showed much higher distance-decay rates than KO and taxonomic profiles. Biotic factors were identified as highly influential in explaining the observed patterns in the functional profiles, whereas temperature and biogeographic province mainly explained the observed taxonomic patterns. Our results thus indicate fine-tuned genetic adaptions of microbial communities to regional biotic and environmental conditions in the Atlantic and Southern Ocean."],["dc.description.sponsorship","Deutsche Forschungsgemeinschaft"],["dc.identifier.doi","10.1038/s41467-022-28128-8"],["dc.identifier.pii","28128"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/105966"],["dc.language.iso","en"],["dc.notes.intern","DOI-Import GROB-530"],["dc.relation.eissn","2041-1723"],["dc.rights.uri","https://creativecommons.org/licenses/by/4.0"],["dc.title","Significance of gene variants for the functional biogeography of the near-surface Atlantic Ocean microbiome"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]

To understand the interactions between DOM and the bacterial community (BC), it is important to identify the key factors on both sides in detail, chemically distinct moieties in DOM and the various bacterial taxa. Next-generation sequencing facilitates the classification of millions of reads of environmental DNA and RNA amplicons and ultrahigh-resolution mass spectrometry yields up to 10 000 DOM molecular formulae in a marine water sample. Linking this detailed biological and chemical information is a crucial first step toward a mechanistic understanding of the role of microorganisms in the marine carbon cycle. In this study, we interpreted the complex microbiological and molecular information via a novel combination of multivariate statistics. We were able to reveal distinct relationships between the key factors of organic matter cycling along a latitudinal transect across the North Sea. Total BC and DOM composition were mainly driven by mixing of distinct water masses and presumably retain their respective terrigenous imprint on similar timescales on their way through the North Sea. The active microbial community, however, was rather influenced by local events and correlated with specific DOM molecular formulae indicative of compounds that are easily degradable.

At the Southern polar front, chitin-supplemented microcosms were characterized by higher fractions of actively growing cells and a community shift from Alphaproteobacteria to Gammaproteobacteria and Bacteroidetes. At the Antarctic ice shelf, chitin degradation was associated with growth of Bacteroidetes, with 24% higher cell numbers compared with the control.

As much of organic matter consists of polymers, investigating the hydrolytic potential among marine bacteria is crucial for the understanding of marine nutrient cycles and their linkages with bacterial community structure. The present study characterized the response of bacterioplankton communities to polymeric carbohydrates at four locations in the Southern and Atlantic Oceans using natural seawater microcosms amended with chitin, alginate, and agarose. Cell numbers as determined by flow cytrometry increased markedly in temperate water microcosms (Patagonian Shelf), yielding almost double cell numbers with alginate and chitin compared to the control regime (3 × 106 cells mL-1). In warm water microcosms (Mauritanian Upwelling), only alginate distinctly stimulated bacterial growth, yielding almost double cell numbers (2.3 × 106 cells mL-1). Cell numbers remained almost unchanged in polar water microcosms (Polar Front, Antarctic Ice Shelf). 454 pyrosequencing as well as CARD-FISH revealed that Gammaproteobacteria were significantly stimulated across all locations and regimes (p < 0.05). Agarose and alginate strongly stimulated Alteromonadaceae in temperate waters, reaching relative abundances of 63 and 78%, respectively. This was largely due to single OTUs related to Pseudoalteromonas atlantica and Alteromonas macleodii, respectively. The response of Colwellia was determined by both location and substrate, being stimulated by agarose and alginate in polar waters and by chitin at all locations except the Antarctic Ice Shelf. The latter instead featured a significant stimulation of Fibrobacteres (reaching 28%). Chitin strongly stimulated Reichenbachiella (Cytophagales) in polar and temperate waters, with relative abundances increasing by 300- to 1500-fold (p < 0.005). At present, several alginate-degrading strains from the Gammaproteobacteria and Bacteroidetes are investigated by physiological and whole-genome analyses, indicating that closely related strains have distinct alginate utilization modes.
