AB - Despite the great potential of photosynthetic microbes in the production of renewable fuels, value-adding
chemicals, and water treatment, etc., commercial utilization of them is significantly hindered by the lack of techniques
to accurately monitor the thermodynamic and kinetic characteristics of the In-situ growth of microbes under
controlled light illumination for optimal cultivation. Herein, we demonstrated that a newly developed highly sensitive
photo-microcalorimetric system successfully captured the impacts of the light wavelength and strength on the
thermodynamic and kinetic parameters of the In-situ growth of Rhodopseudomonas palustris, a representative
photosynthetic microorganism. To our best knowledge, this is the first time that highly precise microcalorimetry is
employed to monitor exam the in-situ growth of photosynthetic microorganisms under controllable photo
illumination. We envision this technique can help for the optimization of the growth conditions of photosynthetic
microorganisms for scale-up applications.
