Biochemical kinetic modelling of a purple phototrophic bacteria mixed 2 culture: Addressing light limitation and photo-inhibition
This dataset contains 16S rRNA gene amplicon sequences obtained from the microbial communities of photobioreactors operated under varying light intensities. The sequences correspond to batch experiments conducted to investigate the effect of monochromatic light intensities (ranging from 10 to 60 W/m^2) on mixed cultures of purple phototrophic bacteria (PPB). The goal of the study was to develop and calibrate a light-dependent kinetic model for PPB growth using a Haldane-type function, incorporating biologically based parameters to account for the response to light. Microbiological characterizations of the cultures revealed selective pressure imposed by light, and the sequence data were used to evaluate the impact of irradiation conditions on community composition. These results contribute to the optimization and scale-up of PPB-based biotechnological processes.
