Cyanobacteria exhibit gliding motility, a unique form of self-propulsion with ecologi cal implications, particularly within microbial communities subjected to fluctuating environmental conditions. Aggregates of cyanobacterial filaments engage in collective motility, with their dynamics modulated by environmental cues such as light exposure and oxidative stress. Building on established frameworks, notably those involving Fluc tiforma draycotensis under stress conditions [1], this study examines the aggregation and motility dynamics within cyanobacterial aggregates, incorporating methodologi cal adaptations to elucidate underlying physical mechanisms at both individual and aggregate scales.
