Cyanobacterial biofactories: combining evolved and synthetic genetic regulatory mechanisms to yield carbon-neutral bioproductsDownload
While cyanobacteria hold the promise of producing useful bioproducts from little more than sunlight and carbon dioxide, their economic feasibility hinges on developing better mechanisms to manipulate gene expression in order to divert photosynthate towards product formation. A recent report...
Mixing displays a major role in the growth of photosynthesis microorganisms in active suspensions: it gives access to nutrients, improves the microorganisms’ exposure to light, and homogenizes temperature distribution in photobioreactors (PBRs). Therefore, mixing is an essential factor in the...
Cyanobacteria are among the most abundant primary producers in the oceans and are present in nearly every environment on the planet. They were one of the first organisms to evolve nearly 3.8 billion years ago, making them excellent analogs for the investigation of ancient ocean chemistry. The...
Expression of the stress-regulated RNA helicase of Synechocystis sp. PCC 6803, CrhR, is altered by three known stresses, temperature, light and salt concentration. Here we show that altering the source of fixed nitrogen, either urea, ammonia, nitrate or lack of fixed nitrogen, also results in...
Redox and Light Derived Mechanisms of Environmental Perception are Utilized for Regulation of the Cyanobacterial RNA Helicase crhRDownload
Cyanobacteria occur worldwide in environments that contain water and sunlight. They are crucial, positive players in carbon, oxygen and nitrogen cycling and function as producers of biosynthetic products such as biofuels. To optimize these processes, understanding mechanisms by which...
The Role of Iron in Suppressing Internal Phosphorus Loading and Toxic Cyanobacterial Blooms in Freshwater LakesDownload
Harmful algal blooms occur in nutrient-rich lakes around the world, diminishing the value of these ecosystems for wildlife and humans. Management of algal blooms is an on-going challenge for lake managers and policy makers. The overarching goal of this research was to advance our understanding of...
