“…For example, Planctomycetales colonize marine particles and algal or abiotic surfaces (12,14,(605)(606)(607), and sulfur-oxidizing, iron-corroding Leucotrichaceae colonize algal and submerged carbon steel surfaces (18, 608). Stalked or prosthecate Caulobacter and Hyphomonas bacteria are primary colonizers of algal or submerged surfaces (246,266,607). It is reasonable to hypothesize that holdfast-mediated irreversible attachment may be a key step in surface colonization by most of these pioneer bacteria.…”

“…For example, Alteromonas species are widespread in the ocean and are common surface-and particlecolonizing bacteria in both shallow and deep waters (243)(244)(245)(246). Alteromonas species are metabolic generalists capable of rapid responses to an environmental disturbance (247)(248)(249).…”

“…Studies have shown that Bacteroidetes bacteria are common in marine environments (791), abundant in organic particle-rich coastal waters (108,113,130,611,791), responsive to algal and jellyfish blooms (272,537,756,(791)(792)(793), copiotrophic (252), and prone to leading a surface-associated life (12,17,246,272,574,607) supported by the extracellular degradation of complex biopolymers such as polysaccharides and proteins (194,791,(794)(795)(796)(797). These bacteria harbor a large number of genes for adhesive exopolysaccharides, adhesion proteins, proteases, peptidases, glycoside hydrolases, and lipases, and several genes for biopolymer degradation are coregulated with the genes for TonBdependent transport systems (794,795,(798)(799)(800)(801)(802).…”

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.

“…Most, if not all, eukaryotes (including Ectocarpus) have evolved complex interactions with bacteria (Zilber-Rosenberg and Rosenberg, 2008). There are several examples where algal-bacterial associations benefit algal hosts, and have become an integral part of their biology (see Goecke et al, 2010;Hollants et al, 2013 for recent reviews): epi-and endophytic bacteria, for instance, are known to provide nitrate (Chisholm et al, 1996) or vitamins (Croft et al, 2006) to their hosts, thus increasing their fitness. Within the Ectocarpales, an absolute dependence on bacteria has been observed in E. fasciculatus as well as Pylaiella littoralis, both of which do not develop properly in axenic conditions, although algal growth can be restored by addition of the cytokinin kinetin to the culture medium (Pedersén 1968(Pedersén ,1973.…”

Host–microbe interactions as a driver of acclimation to salinity gradients in brown algal cultures

et al. 2015

Like most eukaryotes, brown algae live in association with bacterial communities that frequently have beneficial effects on their development. Ectocarpus is a genus of small filamentous brown algae, which comprises a strain that has recently colonized freshwater, a rare transition in this lineage. We generated an inventory of bacteria in Ectocarpus cultures and examined the effect they have on acclimation to an environmental change, that is, the transition from seawater to freshwater medium. Our results demonstrate that Ectocarpus depends on bacteria for this transition: cultures that have been deprived of their associated microbiome do not survive a transfer to freshwater, but restoring their microflora also restores the capacity to acclimate to this change. Furthermore, the transition between the two culture media strongly affects the bacterial community composition. Examining a range of other closely related algal strains, we observed that the presence of two bacterial operational taxonomic units correlated significantly with an increase in low salinity tolerance of the algal culture. Despite differences in the community composition, no indications were found for functional differences in the bacterial metagenomes predicted to be associated with algae in the salinities tested, suggesting functional redundancy in the associated bacterial community. Our study provides an example of how microbial communities may impact the acclimation and physiological response of algae to different environments, and thus possibly act as facilitators of speciation. It paves the way for functional examinations of the underlying host-microbe interactions, both in controlled laboratory and natural conditions.

“…Marine macroalgae (seaweeds) are commonly associated with bacteria that either live on the surface or in the cytoplasm and/or vacuolar systems of the cells [6][7][8]. These bacteria are able to influence the morphogenesis and life cycle of their algal host [9][10][11] and are linked with various metabolic functions such as the production of growth factors, fixed nitrogen and antimicrobial & 2013 The Author(s) Published by the Royal Society.…”

Permanent residents or temporary lodgers: characterizing intracellular bacterial communities in the siphonous green algaBryopsis

The ecological success of giant celled, siphonous green algae in coastal habitats has repeatedly been linked to endophytic bacteria living within the cytoplasm of the hosts. Yet, very little is known about the relative importance of evolutionary and ecological factors controlling the intracellular bacterial flora of these seaweeds. Using the marine alga Bryopsis (Bryopsidales, Chlorophyta) as a model, we explore the diversity of the intracellular bacterial communities and investigate whether their composition is controlled by ecological and biogeographic factors rather than the evolutionary history of the host. Using a combination of 16S rDNA clone libraries and denaturing gradient gel electrophoresis analyses, we show that Bryopsis harbours a mixture of relatively few but phylogenetically diverse bacterial species. Variation partitioning analyses show a strong impact of local environmental factors on the presence of Rickettsia and Mycoplasma in their association with Bryopsis. The presence of Flavobacteriaceae and Bacteroidetes, on the other hand, reflects a predominant imprint of host evolutionary history, suggesting that these bacteria are more specialized in their association. The results highlight the importance of interpreting the presence of individual bacterial phylotypes in the light of ecological and evolutionary principles such as phylogenetic niche conservatism to understand complex endobiotic communities and the parameters shaping them.
