Marine Bacteria and Archaea: Diversity, Adaptations, and Culturability

Impact of grazing, resource availability and light on prokaryotic growth and diversity in the oligotrophic surface global ocean

“…7B), which agrees with the widespread adaptation of sphingomonads to oligotrophic environments (Lauro et al, 2009;Aylward et al, 2013). In addition, oligotrophic bacteria present a reduced transcriptional control compared to copiotrophic bacteria that preclude them to sense and react to environmental fluctuations (Lauro et al, 2009;Gifford et al, 2013;Cottrell and Kirchman, 2016;Overmann and Lepleux, 2016). In addition, oligotrophic bacteria present a reduced transcriptional control compared to copiotrophic bacteria that preclude them to sense and react to environmental fluctuations (Lauro et al, 2009;Gifford et al, 2013;Cottrell and Kirchman, 2016;Overmann and Lepleux, 2016).…”

“…Both SAR11 and Prochlorococcus are well-known representatives of the oligotrophic lifestyle in the marine realm (Overmann and Lepleux, 2016). A member of the Sphingobium genus was also negatively affected by dilution (Fig.…”

“…Thalassococcus genus) and Thalassospira (Fig. A recent review on adaptations of oligotrophic bacteria highlights their characteristically low loss rates by top-down agents such as protistan grazers or viruses (Overmann and Lepleux, 2016; and references therein). The bacterial taxa negatively affected by filtration, such as OM60 (NOR5) Gammaproteobacteria or Prochlorococcus (Fig.…”

“…A member of the Sphingobium genus was also negatively affected by dilution (Fig. Oligotrophic bacteria are typically very abundant and exhibit a series of adaptations that allow them to succeed in very diluted environments, including their small sizes, streamlined genomes, high grazing and viral infection resistance, or slow but constant growth irrespective of substrate concentration (Cottrell and Kirchman, 2016;Overmann and Lepleux, 2016;Dadon-Pilosof et al, 2017). Oligotrophic bacteria are typically very abundant and exhibit a series of adaptations that allow them to succeed in very diluted environments, including their small sizes, streamlined genomes, high grazing and viral infection resistance, or slow but constant growth irrespective of substrate concentration (Cottrell and Kirchman, 2016;Overmann and Lepleux, 2016;Dadon-Pilosof et al, 2017).…”

“…The permanent stratification of tropical and subtropical oceans reduces nutrient supply to the upper layers (Longhurst, 2010), originating a large nutrient-depleted habitat where light intensity and depth penetration are large (Tedetti and Sempéré, 2006). Pelagibacter (SAR11) and Prochlorococcus are two wellknown genera representative of the oligotrophic lifestyle (Overmann and Lepleux, 2016). Pelagibacter (SAR11) and Prochlorococcus are two wellknown genera representative of the oligotrophic lifestyle (Overmann and Lepleux, 2016).…”
