3D image reconstruction of a ‘macrofloc’ (FG-5) and the influence of filamentous microbes on floc structure. (a) 3D rendering of a ‘macrofloc’ (FG-5) clearly composed of smaller floc units (FG-4). (b) Sub-volume containing one of the FG-4 units identified in (a) but with minerogenic material render transparent to reveal the filamentous bacteria that act as a ‘backbone’ for the floc. Note the elongated, non-spherical shape of the floc which is directed by the filamentous morphology of the cyanobacteria. Protruding filamentous bacteria (PFB) act as ‘anchor points’ to join FG-4 units together (see a). 3D renderings were generated using Drishti v2.6.2 (https://github.com/nci/drishti). The figure was created using Adobe Illustrator CS6 (https://www.adobe.com/uk/).
