“…These electrons are transported via the ETC, and iron-sulfur protein ferredoxin (PetF) or NAD(P)H via FNR (ferredoxin/NAD(P) H oxidoreductase) acts as an e À donor to [FeFe] or [NiFe] hydrogenase, respectively. In algae, ferredoxin directly linked to synthesize H 2 via the ETC and in cyanobacteria NAD(P)H donates e À to [NiFe] bidirectional hydrogenase to synthesize H 2 (Kufryk et al, 2013). Adenosine triphosphate and NADPH generated by light reaction are used to fix CO 2 during a dark reaction.…”

A new cyanobacterial strain was isolated and purified from salt Lake Balkhash, Kazakhstan. According to its morphological and ultrastructural characteristics, 16S rRNA sequence and the fatty acid profile, the strain has been classified as Cyanobacterium spp. and assigned as Cyanobacterium sp. IPPAS B-1200. The strain is characterized by a non-temperature inducible ∆9-desaturation system, and by high relative amounts of myristic (14:0-30%) and myristoleic (14:1∆9-10%) acids. The total amount of C 14 fatty acids reaches 40%, which is unusually high for cyanobacteria, and it has never been reported before. The remaining fatty acids are represented mainly by palmitic (16:0) and palmitoleic (16:1∆9) acids (the sum reaches nearly 60%). Such a fatty acid composition, together with a relatively high speed of growth, makes this newly isolated strain a prospective candidate for biodiesel production.

“…As cyanobacterial nitrogenase activity is inhibited by oxygen and nitrogen source such as nitrate, hydrogen is usually generated in oxygen and nitrogen deprived cultures. Once the activity of nitrogenase is stimulated, hydrogen reduction by nitrogenase can last for a long period even in the absence of nitrogen gas (Kufryk, 2013;Min and Sherman, 2010).…”

Dynamic simulation models for cyanobacterial hydrogen production process. Parameter estimation via dynamic optimisation. Proposed modified models exhibit higher accuracy for real process simulation. Interpretation of higher performance of CSTR over PFR for this process. Fed-batch processes are proposed as the optimal reactor operation. a b s t r a c t Cyanothece sp. ATCC 51142 is considered a microorganism with the potential to generate sustainable hydrogen in the future. However, few kinetic models are capable of simulating different phases of Cyanothece sp. ATCC 51142 from growth to hydrogen production. In the present study four models are constructed to simulate Cyanothece sp. batch photoproduction process. A dynamic optimisation method is used to determine parameters in the models. It is found that although the piecewise models fit experimental data better, large deviation can be induced when they are used to simulate a process whose operating conditions are different from the current experiments. The modified models are eventually selected in the present study to simulate a two-stage continuous photoproduction process. The current simulation results show that a plug flow reactor (PFR) shows worse performance compared to a continuous stirred-tank reactor (CSTR) in the current operating conditions since it lowers the total hydrogen production. The finding is that nitrate and oxygen concentration change along the direction of culture movement in PFR, and hydrogen is only generated in the zone where both of them are low. The reactor area thereby is not well utilised. Additionally, as hydrogen production rate is primarily influenced by biomass concentration, which increases initially and decreases eventually along the direction of culture movement, the overall hydrogen production rate in a PFR may be lower than that in a CSTR. Finally, in this study fed-batch photoproduction processes are proposed containing only one photobioreactor based on the current simulation.
