Abstract Nutrient-induced blooms of the globally abundant freshwater toxic cyanobacterium Microcystis cause worldwide public and ecosystem health concerns. The response growth toxin production to new recycled nitrogen (N) inputs impact heterotrophic bacteria in phycosphere on these processes are not well understood. Here, using microbiome transplant experiments, cyanotoxin analysis, nanometer-scale stable isotope probing measure N incorporation exchange at single cell resolution, we monitored growth, production, community structure several strains grown amino acids or proteins as sole source. We demonstrate that type organic available shaped microbial associated with Microcystis, external input led decreased bacterial colonization colonies. Our data also suggest certain could directly uptake acids, but lower rates than bacteria. Toxin analysis showed biomass-specific microcystin was impacted by source (i.e. nitrate, protein) rather total availability. Single-cell revealed some communities competed for N, other promoted increased likely through ammonification modification. laboratory culture support nature, Microcystis-associated play critical roles this process influencing cyanobacterial succession either decreasing (via competition) increasing biotransformation) availability, especially under inorganic scarcity.

Abstract Freshwater harmful algal blooms are often dominated by Microcystis , a phylogenetically cohesive group of cyanobacteria marked extensive genetic and physiological diversity. We have previously shown that this diversity the presence microbiome heterotrophic bacteria influences competitive interactions with eukaryotic phytoplankton. In study, we sought to explain these observations characterizing Monod equation parameters for resource usage (maximum growth rate μ max half‐saturation value K s, quota) as function N P levels four strains (NIES‐843, PCC 9701, 7806 [WT], Δ mcyB ) in absence derived from isolated Lake Erie. Results indicated limited differences maximum rates but more pronounced values among strains. The largest impact was reducing minimal nitrogen concentration sustaining half saturation values, variable results depending on strain. also differed each other their quotas extent which affected them. Our data highlight importance altering ‐intrinsic traits, strain hierarchies, thus bloom dynamics. As quota, s commonly used models blooms, our suggest model improvement may be possible incorporating genotype dependencies resource‐use parameters.
