Abstract

Algae and bacteria have coexisted ever since the early stages of evolution. This coevolution has revolutionized life on earth in many aspects. Algae and bacteria together influence ecosystems as varied as deep seas to lichens and represent all conceivable modes of interactions - from mutualism to parasitism. Several studies have shown that algae and bacteria synergistically affect each other's physiology and metabolism, a classic case being algae-roseobacter interaction. These interactions are ubiquitous and define the primary productivity in most ecosystems. In recent years, algae have received much attention for industrial exploitation but their interaction with bacteria is often considered a contamination during commercialization. A few recent studies have shown that bacteria not only enhance algal growth but also help in flocculation, both essential processes in algal biotechnology. Hence, there is a need to understand these interactions from an evolutionary and ecological standpoint, and integrate this understanding for industrial use. Here we reflect on the diversity of such relationships and their associated mechanisms, as well as the habitats that they mutually influence. This review also outlines the role of these interactions in key evolutionary events such as endosymbiosis, besides their ecological role in biogeochemical cycles. Finally, we focus on extending such studies on algal-bacterial interactions to various environmental and bio-technological applications.

Fig. 1 A pictorial representation of evolution of algae after primary (PE) and secondary endosymbiosis (SE) events. The green branches indicate the green lineage while the red branches indicate the red lineage respectively. The dashed lines indicate the presence of sub-groups within the respective lineages where primary and/or secondary endosymbiosis is known to have occurred.

Fig. 2 Confocal laser scanning images merged with differential interference contrast microscopic images of several multicellular algae and their closest unicellular relative. The strains were stained with SYBR green and pseudo-colored in yellow. The images reveal the presence of bacteria in all strains, including V. carteri (B), especially in flagellates and outer layers of ECM (A & B) whereas the gonidia do not have significant bacterial presence on their outer surface (C). The scale bar represents 5 μ m.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
