Photogranules are dense algal-bacterial aggregates used in aeration-free and carbon-negative wastewater treatment, wherein filamentous cyanobacteria (FC) essential components. However, little is known about the functional role of symbiotic bacteria photogranulation. Herein, we combined cyanobacterial isolation, reactor operation, multiomics analysis to investigate cyanobacterial-bacterial interaction during The addition FC inoculated sludge achieved a 1.4-fold higher granule size than control, aggregation capacity FC-dominant photogranules was closely related extracellular polysaccharide (PS) concentration (R = 0.86). Importantly, found that cross-feeding between for macromolecular PS synthesis at heart photogranulation substantially enhanced granular stability. Chloroflexi-affiliated intertwined with throughout promoted biosynthesis using partial nucleotide sugars produced by FC. Proteobacteria-affiliated were spatially close FC, highly expressed genes vitamin B1 B12 synthesis, contributing necessary cofactors promote proliferation. In addition, Bacteroidetes-affiliated degraded FC-derived carbohydrates influenced granules development. Our metabolic characterization identified shed light on critical interactions from viewpoint cross-feeding.

Microbial mats are stratified communities often dominated by unicellular and filamentous phototrophs within an exopolymer matrix. It is challenging to quantify the dynamic responses of community members in situ as they experience steep gradients rapid fluctuations light. To address this, we developed a binary consortium using two representative isolates from hot spring mats: oxygenic phototrophic cyanobacterium Synechococcus OS-B' (Syn OS-B') anoxygenic phototroph Chloroflexus MS-CIW-1 (Chfl MS-1). We quantified motility individual cells entire colonies demonstrated that Chfl MS-1 formed bundles filaments moved all directions with no directional bias Syn was slightly less motile but exhibited positive phototaxis. This displayed cooperative behavior moving further than either species alone ordered arrays where both aligned light source. No observed when nonmotile pilB mutant used instead OS-B'. The also produced more adherent biofilm species, consistent close interspecies association revealed electron microscopy. propose cyanobacteria Chloroflexota cooperate forming natural microbial colonizing new niches building robust biofilms.
