Introducing multiple genomic alterations into cyanobacteria is an essential tool in the development of strains for industrial and basic research purposes. We describe a system for generating unmarked mutants in the model cyanobacterial species Synechocystis sp. PCC6803 and marked mutants in Synechococcus sp. PCC7002.

Laboratory Simulation of an Iron(II)-rich Precambrian Marine Upwelling System to Explore the Growth of Photosynthetic Bacteria

We simulated a Precambrian ferruginous marine upwelling system in a lab-scale vertical flow-through column. The goal was to understand how geochemical profiles of O2 and Fe(II) evolve as cyanobacteria produce O2. The results show the establishment of a chemocline due to Fe(II) oxidation by photosynthetically produced O2.

Here, we describe methods of sampling from the euphotic zones of marine and freshwater ecosystems to isolate cyanophages (and their hosts) and post-sampling processes that enrich single genotypes and characterize virus-host interaction dynamics.
FAQs
Thylakoid membranes organize photosynthetic pigments and electron-transfer systems within the cell. When these systems are driven by sunlight, they support the production of ATP and reducing power, which provide energy and chemical capacity for downstream cellular processes. Studying this membrane-based organization helps researchers connect photosynthetic activity with microbial growth and metabolism.
Carbon fixation links captured carbon dioxide to the cell’s metabolic activities, while regulatory networks coordinate this process with growth and changing cellular demands. These controls prevent photosynthetic energy production from being studied in isolation. In S. elongatus, they provide a framework for examining how metabolism is integrated with physiology and how cells regulate carbon assimilation.
Daily cellular rhythms coordinate biological activities over recurring day-night cycles. In S. elongatus, circadian regulation offers a tractable system for studying how timing information interacts with photosynthesis, metabolism, and growth. This makes the organism useful for investigating biological timekeeping alongside core physiological processes rather than treating regulation as a constant, unchanging response.
Its relatively simple genetic system allows researchers to examine photosynthesis and microbial physiology while connecting genetic changes to cellular functions. The organism also combines oxygen-producing photosynthesis with regulated carbon assimilation and daily rhythms. Together, these features make it a useful model for studying several interacting biological processes within one comparatively accessible cyanobacterial system.
Scientists can use the organism’s relatively simple genetic system to study how cellular functions are controlled and to engineer strains with selected metabolic properties. This approach supports investigations of photosynthesis, carbon assimilation, and microbial physiology, while also enabling work aimed at sustainable bioproduction. The resulting strains can serve as experimental systems for connecting genetic design with metabolic outcomes.
S. elongatus supports research on sustainable bioproduction because its photosynthetic metabolism can be studied and engineered toward renewable compounds. The overview specifically identifies biofuels and other renewable products as application areas. These efforts extend fundamental work on carbon fixation and energy conversion into research concerned with producing useful chemicals through biologically based systems.
