(Submitter supplied) Cyanobacteria are oxygenic photoautotrophs responsible for a substantial proportion of nitrogen fixation and primary production in the hydrosphere. Non-nitrogen fixing cyanobacteria, such as Synechocystis sp. PCC 6803, depend of the availability of nitrogenized species to survive. Therefore, an intricate regulatory network around the transcriptional factor NtcA maintains the homeostasis of nitrogen in these organisms. more...

(Submitter supplied) Unicellular cyanobacteria that do not fix nitrogen can survive prolonged periods of nitrogen starvation as bleached cells in a non-growing, dormant state. Upon re-addition of a usable nitrogen source, bleached cultures re-green within 48 hours and the cells return to vegetative growth. Here we investigated the process of resuscitation at the physiological and molecular level. Almost immediately upon nitrate addition, the cells initiate an amazingly organized resuscitation program: they first turn on respiration, gaining energy and activating the genes of the entire translational apparatus, genes for ATP synthesis and nitrate assimilation. more...

(Submitter supplied) Nitrogen starvation is an efficient environmental pressure used to increase lipid accumulation and oil droplet formation in microalgal cells. Various studies focused on metabolic changes occurring in microalgae in nitrogen starvation conditions, but the mechanisms at the basis of these changes are not completely understood. Between microalgae, green algae, with more than 7000 species growing in a variety of habitats, have been frequently studied for energy purposes, but also as source of bioactive extracts/compounds. more...

(Submitter supplied) Background: High-energy-density biofuels are typically derived from the fatty acid biosynthesis pathway, thus establishing free fatty acids (FFAs) as important fuel precursors. FFA production using photosynthetic microorganisms like cyanobacteria allows for direct conversion of carbon dioxide into fuel precursors. Recent studies investigating cyanobacterial FFA production have demonstrated the potential of this process, yet FFA production was also shown to have negative physiological effects on the cyanobacterial host, ultimately limiting high yields of FFAs. more...

(Submitter supplied) Biofilm formation by photosynthetic organisms is a complex behavior that serves multiple functions in the environment. Biofilm formation in the unicellular cyanobacterium Synechococcus elongatus PCC 7942 is regulated in part by a set of small secreted proteins that promotes biofilm formation and a self-suppression mechanism that prevents their expression. Little is known about the regulatory and structural components of the biofilms in PCC 7942, or response to the suppressor signal(s). more...
