Cyanobacteria Blooms and the reaction with Dynamic Microbiomes

Figure. Metatranscriptomes were re-examined to demonstrate shifts. A) community richness (rpob phylogenies) and B) functional richness or unique KEGG orthology assignments of the re-occuring microbiome. The data results show that only small components of communit and function are 4% and 15% respectively that remained common after 3 generations. 

In nature, the natural process of bacteria persisting in fresh water environments depends on the effect of weather, organisms, etc. In the laboratory, scientist are able to manipulate the reduction of contaminants and creating pure cultures. Without microbiomes and the relationship of cyanobacteria the process is limited and complications may occur in research. Microcystis aeruginosa NIES-843 cultures were in light limited control with different sources and reduced conditions in samples that were cultivated identical microbiomes for 3 cycles of growth. On the right hand side on the image, we are able to depict that there is nutrient availability from the shift in microbiomes. Specifically, Microcystis aeurginosa NIES-843 cultures that were started from the same stock and transferred for 3 generations to Nitrogen and Phosphorus conditons to experiment how cyanobacterium would react (Steffen et al. 2014). A series of questions such as to what extent can a microbe's microbiome affect gene expression & what biological pattern can scientists expect to see in nature in combination with cell interaction, chemistry, physics, etc. within changing environments.
