摘　　要：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.
