Experiments aim to reveal the dynamic features that occur during the metabolism of the unicellular, nitrogen fixing cyanobacterium Cyanothece sp. when exposed to diverse circadian forcing patterns (LD 16:8, LD 12:12, LD 8:16, LD 6:6).

The genome of Cyanothece 51142, a unicellular diazotrophic cyanobacterium important in the marine nitrogen cycle
kegg:T00686
As the biotechnological potential of Cyanothece 51142 varies with the time of the day, the argument that it will, similarly, depend on the phase of the culture growth is provided. Here the study of batch culture dynamics to discover the dominant constraints in the individual growth phases and identify potential for inducing or delaying transitions between culture growth phases in Cyanothece 51142 is presented.

SevenMulti™ is the perfect choice for applications where maximum measurement accuracy is required. The dual-channel instrument supports the measurement of two electrochemical parameters simultaneously and can be expanded by additional modules. It meets the latest requirements for quality control, data management and legal GLP regulations. The self-explanatory user interface allows intuitive operation at all stages.

The Photobioreactor FMT 150 has a flat-vessel design that enables uniform illumination over the whole culture. Growth of cultures is monitored by the integrated densitometer (OD 720 nm, 680 nm). Relative chlorophyll content of cultures can also be monitored continuously by the difference of optical densities at 680 and 720 nm. Instantaneous physiological state of the culture is measured by the Photosystem II quantum yield Fv/Fm.

The OxyCorder is primarily used to measure dissolved oxygen in photosynthesis research. Therefore the impedance of three independent input channels is preset for different electrode sizes: 4 MΩ (Channel 1), 1.3 MΩ (Channel 2), and 33 kW (Channel 3 - for large electrodes, as bare platinum-silver). The fourth input channel enables voltage reading. The QxyCorder is supplied with OxyWin software that controls polarization voltage of the electrodes (0 to 1000 mV, two 10 bit A/D converters) and also enables displaying and analyzing the measured data.
