Effects of light and temperature on the photoautotrophic growth and photoinhibition of nitrogen-fixing cyanobacterium Cyanothece sp. ATCC 51142

Modelling light transmission, cyanobacterial growth kinetics and fluid dynamics in a laboratory scale multiphase photo-bioreactor for biological hydrogen production

“…However, when the cyanobacteria concentration is higher than 30 mg L −1 (~2.0 g dry biomass L −1 ), which is found in the final growth period of our experiments [7], K a increases up to 4.017 m −1 [19] which is about three times higher than before. As a result, the influence of cyanobacterial absorption becomes significant (average light intensity is about 10.2% lower than before) and only Eqs.…”

“…(21) have been measured from previous experiments in a tubular PBR [7]. Although the current research focuses on the study of flat plate PBR, the similar thickness of the two reactors leads to comparable performance when researching the influence of light intensity on cyanobacteria growth.…”

Isolation Purification and Culturing of Cyanobacteria and Microalgae towards Biodiesel Production: Current Status

“…A non-linear relationship between the maximum specific growth rate and the irradiance up to 320 μE m − 2 s − 1 was identified and found to be dominated by light saturation rather than photo inhibition. The relationship between the specific growth rate and the temperature was found to be linear until a remarkable drop in the final biomass productivity and cyanobacterial photosynthetic capability was observed at 40 °C (Dechatiwongse et al, 2014). Biodiesel production from microalgae through experimental investigation of transesterification conditions reported that 3.4:1 methanol dry algal biomass ratio with 35 minutes reaction time and 0.6:1 catalyst to dry biomass ration was the most efficient in experimental process.…”

“…A high degree of coherence between cyanobacterial growth and nutrient uptake kinetics was observed, as well as a strong dependence on the change of the two parameters-light intensity and temperature (Dechatiwongse et al, 2014). A study carried out to analyze the effect of light intensity and temperature, on the photoautotrophic growth of Cyanothece and showed that nitrogen depletion was confirmed as a trigger, which transforms an exponential into a stationary growth phase.…”

Demonstration of a two-stage aerobic/anaerobic chemostat for the enhanced production of hydrogen and biomass from unicellular nitrogen-fixing cyanobacterium

“…which was based on a set of 32 individual gravimetrically determined data points, R 2 = 0.9617 [39].…”
