four engineered strains were constructed by individually overexpressing potential ammonia transporters OmpC, OmpF, OmpN, and PhoE. In the shake-flask fermentation test, strains overexpressing OmpF and OmpN exhibited positive effects on lysine production (Supplementary Fig.7). Thus, both genes were co-ex...
Finally, ammonia treated FTO substrate was rinsed with deionized water and annealed at 150 °C 1h. Prior to every electrochemical experiment, the solution resistance was measured in the electrolysis bath. All the data were iR-compensated. EPR Study. All EPR measurements were carried out at...
To identify those genes with a significant role in nitrogen fixation, we accomplished a comparative analysis between the gene expression profile at the nitrogen fixation stage and under free-living conditions in R etli, this last condition mainly defined by succinate and ammonia as carbon and ...

However, when ammonia was the limiting inorganic nutrient, a slight increase (of approximately 10%) in C10 was observed. When both carbon and nitrogen were bellow the detection limit in the chemostat, the monomer com- position of the polymer was almost the same as the one observed in ...
By prolonging the culture time, the total carbohydrate content in the biomass was doubled due to the stress produced by ammonia nitrogen deficiency mainly. Based on the high removal efficiency of N and P (80% and 97.7%, respectively) and total carbohydrate content (31.1%), it was concluded ...
It has been reported that enzymes may be inactivated at a pH level that is less than or greater than the optimum value causing a reduction in cell growth and ethanol fermentation ability [48]. The initial pH of the SSJ was in the range of 5.2–5.5. Therefore, a pH of 5.5, which ...
The pH was controlled at 7.4 by adding 15% aqueous ammonia, and the dissolved oxygen level was constantly adjusted to 30% by controlling the agitation speed, airflow, and supplemental pure oxygen flow during batch and fed-batch fermentation. 2.5. Measurement of Secretory PlaA Activity PlaA ...
