TL;DR: This work proposes the use of biofuels derived from aquatic microbial oxygenic photoautotrophs, more commonly known as cyanobacteria, algae, and diatoms, to mitigate some of the potentially deleterious environmental and agricultural consequences associated with current land-based-biofuel feedstocks.

TL;DR: Environmental and nutritional conditions that increase anaerobic ATP production, prior glycogen accumulation (in the light), and the intracellular reduction potential (NADH/NAD+ ratio) are shown to be the key variables for elevating H2 evolution.

TL;DR: For cultures grown at all salt concentrations, hydrogen was produced, but its yield did not correlate with increased catabolism of soluble carbohydrates, and ethanol excretion becomes a preferred route for fermentative NADH reoxidation, together with intracellular accumulation of reduced products of acetyl coenzyme A (acetyl-CoA) formation when cells are hypoionically stressed.

TL;DR: It is concluded that the bidirectional hydrogenase in cyanobacteria primarily functions as a redox regulator for maintaining a proper oxidation/reduction state in the cell.

TL;DR: Deletion of the gene encoding glucose-1-phosphate adenylyltransferase (ΔglgC) in the non-nitrogen-fixing cyanobacterium, Synechocystis sp.
