“…The Roseobacter ‐clade bacteria are aerobic anoxygenic phototrophs (which also include Porphyrobacter ) that can use energy from light while growing on organic substances as carbon source (Koblížek, 2015). Members of this clade are reported to favour algal growth (Grossart and Simon, 2007; Seyedsayamdost et al ., 2011; Luo and Moran, 2014; Park et al ., 2017), although some representatives are able to turn the mutualistic relationship into a parasitic one, lysing algal cells to feed on the intracellular substances, when molecules signalling algal cell ageing are released (Seyedsayamdost et al ., 2011). A stimulating effect of the Roseobacter ‐clade representative Pelagibaca bermudensis on T. striata growth was reported under P‐limitation, possibly implying a P recycling activity of this bacterium (Park et al ., 2017).…”

“…strain AG2, performed similarly in vitamin‐added and vitamin‐free medium. Roseobacter ‐clade representatives are reported to be able to synthesize vitamin B 12 (Tang et al ., 2010), but only about half are able to synthesize vitamins B 1 and B 7 (Luo and Moran, 2014). An auxotrophy for these latter vitamins may explain the different behaviour of Roseivivax halotolerans strain LBG3 (significant decrease in bacterial number during growth in vitamin‐free medium) compared with Nautella italica strain CIar and Ponticoccus sp.…”

SummaryAlgal cultures are usually co‐cultures of algae and bacteria, especially when considering outdoor mass cultivation. The influence of associated bacteria on algal culture performance has been poorly investigated, although bacteria may strongly affect biomass (or derived product) yield and quality. In this work, the influence on growth and productivity of Tetraselmis suecica F&M‐M33 of bacterial communities and single bacterial isolates from the algal phycosphere was investigated. Xenic laboratory and outdoor cultures were compared with an axenic culture in batch. The presence of the bacterial community significantly promoted culture growth. Single bacterial isolates previously found to be strictly associated with T. suecica F&M‐M33 also increased growth compared with the axenic culture, whereas loosely associated and common seawater bacteria induced variable growth responses, from positive to detrimental. The increased growth was mainly evidenced as increased algal biomass production and cell size, and occurred after exhaustion of nutrients. This finding is of interest for biofuel production from microalgae, often attained through nutrient starvation processes leading to oil or carbohydrate accumulation. As axenic T. suecica F&M‐M33 showed a similar growth with or without vitamins, the most probable mechanism behind bacterial positive influence on algal growth seems nutrient recycling.

“…For example, some marine bacteria, such as those affiliated with the SAR11 and SAR86 lineages, are mainly free-living (754,755), while the marine Rhodobacteraceae group of the Alphaproteobacteria (i.e., the MRC), the Alteromonadaceae and Vibrionaceae groups of the Gammaproteobacteria, and Bacteroidetes (mainly the Flavobacteria group) are frequently surface associated (13,272). The separation of the free-living and surface-associated lifestyles is likely a result of long-term evolution, and these distinct capabilities are deeply rooted in microbial genetics (756)(757)(758). The ecophysiology of surface-associated marine Alteromonas and Vibrio is discussed above, so the foci of this section are the MRC and Bacteroidetes.…”

“…Some of the MRC bacteria produce auxins (such as indoleacetic acid), essential vitamins, and siderophores, entering into mutualistic relationships with algae (272,595,603,610,758,762,765,773,774). All MRC bacterial genomes harbor the genes that encode c-di-GMP signaling systems, and more than half of the MRC genomes harbor the genes that encode motility, chemotaxis, and diverse chemoreceptor proteins (8,595,609,682,762,775), likely important in locating algae and establishing tight interactions and associations (8,595,776).…”

SUMMARYBiotic and abiotic surfaces in marine waters are rapidly colonized by microorganisms. Surface colonization and subsequent biofilm formation and development provide numerous advantages to these organisms and support critical ecological and biogeochemical functions in the changing marine environment. Microbial surface association also contributes to deleterious effects such as biofouling, biocorrosion, and the persistence and transmission of harmful or pathogenic microorganisms and their genetic determinants. The processes and mechanisms of colonization as well as key players among the surface-associated microbiota have been studied for several decades. Accumulating evidence indicates that specific cell-surface, cell-cell, and interpopulation interactions shape the composition, structure, spatiotemporal dynamics, and functions of surface-associated microbial communities. Several key microbial processes and mechanisms, including (i) surface, population, and community sensing and signaling, (ii) intraspecies and interspecies communication and interaction, and (iii) the regulatory balance between cooperation and competition, have been identified as critical for the microbial surface association lifestyle. In this review, recent progress in the study of marine microbial surface colonization and biofilm development is synthesized and discussed. Major gaps in our knowledge remain. We pose questions for targeted investigation of surface-specific community-level microbial features, answers to which would advance our understanding of surface-associated microbial community ecology and the biogeochemical functions of these communities at levels from molecular mechanistic details through systems biological integration.

The major fatty acid is C 18 :1 ω7 c or summed feature 8 (C 18 :1 ω7 c /ω6 c ). The major quinone is ubiquinone 10. Abundant in the surface layers of the ocean. Species have been isolated from marine sand, marine sediment, rhizosphere soil of mangrove trees, hot springs, the upper 3,000 m of marine environments, the brine–seawater interface, and the interiors of ark clams ( Scapharca broughtonii ), oysters, and sea squirts ( Halocynthia roretzi ).
