Enhancing the Industrial Potential of Filamentous Cyanobacteria
… were to improve the industrial potential of filamentous N2-fixing cyanobacteria by increasing its biofuel tolerance, and to evaluate the economic feasibility and environmental impacts of a theoretical, cyanobacteria-based biofuel production facility. To develop a method to quantify …

Exploring the silicification of microbes and understanding their role in the fossil record
Filamentous cyanobacteria that built macroscopic tufted mats in Proterozoic peritidal environments were fossilized by silicification, but the environmental and biological factors that shaped these structures and enabled this type of preservation are not well understood. Recent work has shown that …

Characteristics of cone-forming cyanobacteria and implications for the origin of conical stromatolites
… and stromatolites. To elucidate the role of the cyanobacteria, we enrich cyanobacteria from modern hot-spring communities of cone-forming microbes and subsequently test how the formation of conical structures depends on individual strains of the community. In our analysis, we augment …

Utility of Ion Mobility – Mass Spectrometry in Peptidoglycan Structural Determination
… and collision cross section (CCS). PG of two filamentous cyanobacteria, Nostoc commune and Limnospira platensis, were chosen for this work as they have not been characterized before now despite commonplace use as sources of nutrition. The analyses revealed that muropeptides can be organized …

Biological nitrogen fixation in a nitrogen limited tropical lake, Lake Chapala, Mexico.
… Chapala when mixed with known nitrogen-fixing cyanobacteria. Greater nitrogen fixation by the added cyanobacteria was found with greater available nitrogen in the water. Also, the rate of nitrogen fixation by the introduced cyanobacteria increased when the water from Lake Chapala was filtered. …

Exploring the Potential of Algae-Bacteria Communities For Biotechnology
… organisms ranging from prokaryotic cyanobacteria to eukaryotic algae spread across many phyla. Traditional algal biotechnology approaches have focused on growing algae in monoculture, in contrast to nature, where algae live in association with many other organisms. One association of …

Contributions to the Proterozoic and Cambrian Evolution of Eukaryotes
… that represent the primary producers' cyanobacteria and eukaryotic phytoplankton (acritarchs). Careful investigation of the basal Cambrian Yanjiahe Formation in the Yangtze Gorges area and the Yurtus Formation in the Aksu area revealed abundant acanthomorphic acritarchs, clustered …
