Microcystin can occupy certain sites on the enzymes important for life processes in the bacteria.

Molecular data can and are being combined with microbial ecosystem models, but to keep up with and take advantage of the full scope of observations, models need to become more mechanistically detailed and complex, which is a technical and cultural challenge for the ecological modeling community.Īgent-based modeling individual-based modeling microbial ecology model calibration model validation modeling. While microcystin is a strong toxin for humans and animals, it’s highly beneficial for cyanobacteria, said Ferdi Hellweger, chair of Water Quality Engineering at TU Berlin’s Institute of Environmental Technology and lead author of the Science paper. It then reviews 16 studies that compared model results with molecular observations. This article presents a framework that aligns observations and models along the dimension of abstraction or biological organization-from raw sequences to ecosystem patterns for observations, and from sequence simulators to ecological theory for models. PMID: 30175444 DOI: 10.1111/1462-2920.14397 Abstract Recent observations of natural bacterial communities show high genetic diversity in organic carbon uptake systems (microdiversity) and specificity in substrate species taken up. Dynamic modelling of mixotrophic microalgal photobioreactor systems with time-varying yield coefficient for the lipid consumption (2014) Sung Jin Yoo et al. 2 Department of Microbiology, University of Tennessee, Knoxville, TN, USA. Models predict planned phosphorus load reduction will make Lake Erie more toxic (in review).
A grand challenge is to use these data to improve predictive models and use models to explain observed patterns.

The catch: the toxin is extremely beneficial While microcystin is a strong toxin for humans and animals, it’s highly beneficial to cyanobacteria, says Professor Dr. Advances in technologies for molecular observation are leading to novel types of data, including gene, transcript, protein, and metabolite levels, which are fundamentally different from the types traditionally compared with microbial ecosystem models, such as biomass (e.g., chlorophyll a) and nutrient concentrations.
