Texte intégralSince its discovery more than 10 years ago, there are more and more studies about proteorhodopsin. This protein seems to be significant in marine ecology considering its large global distribution among many bacterial taxa; but its role remains controversial. Although light response from proteorhodopsin-containing prokaryotes (PCPs) seems to be strain-dependent, it has been hypothesized that the main function of proteorhodopsin was to provide an advantage to PCPs during starvation conditions. In this work, we investigated the increase knowledge about the role of proteorhodopsin regarding the organic carbon utilization efficiency measured in the proteorhodopsin-containing Gammaproteobacterium (Photobacterium angustum S14) in the light compared to the dark. Carbon-limited continuous cultures have been used to mimic environmental conditions. Yields and energetic maintenance were determined according to Pirt’s model (1965) with acid pH or without supplementary pH-stress. We observed highest energetic maintenance in the dark under pH stress condition. However, when light-dark cycles were used, the energy required for bacterial maintenance was significantly decreased during all the run and nearly in the range without pH stress. Taking together, it seems that the response of P. Angustum S14 to light is more linked to the energetic balance than substrate concentration. The innovative results indicate a possible reason why many studies did not observe positive effects on bacterial growth and yield. In addition, PCP sequencing was performed to confirm these conclusions at a more large taxa scale

Texte intégralIron (Fe) is an essential element for marine microbial growth but is present in trace amounts in the surface waters of the ocean. In heterotrophic bacteria, Fe-limitation particularly impacts ATP production and have been shown to implement various strategies to cope in the presence of Fe-limitation. Genetic tools enabled us to test two potential strategies within the model organism Photobacterium angustum S14. The glyoxylate shunt, a metabolic pathway found in aerobic bacteria bypassing several steps within the classic tricarboxylic acid (TCA) was shown to be upregulated under Fe-limitation and we propose that the glyoxylate shunt was able to redirect a cell’s metabolism away from Fe-limiting steps within the electron transport, thereby increasing the metabolic efficiency of the cell under Fe-limitation. Proteorhodopsin, a light activated proton pump found in several heterotrophic bacteria, could alleviate Fe-stress if the produced proton gradient is coupled to ATP synthase. Our results showed that proteorhodopsin is upregulated as cells approached the stationary phase under both Fe-replete and Fe-limiting conditions but was absent during the exponential phase. Future work in elucidating the role of proteorhodopsin, and particularly under Fe-limitation, should therefore focus on the stationary phase of a bacterial cell. The results from this thesis manuscript contributed to a culminating body of work surrounding the versatility of marine heterotrophic bacteria in coping with Fe-limitation and is an appropriate addition to the literature surrounding the role of proteorhodopsin and the glyoxylate shunt within the marine environment
