It has been reported that the parental PB11 strain has a reduced glycolytic flux as part of a carbon limitation response compared with PB12 (Flores et al., 14, 11, 12, 13).
Additionally, adenosine deaminase, an enzyme involved in intracellular nitrogen scavenging, showed enhanced expression, suggesting that FFA-producing cells had activated a nitrogen limitation response.
Strains lacking PTS can co-utilize several carbon sources due to the lack of catabolite repression exerted by PTS, and their glycolytic flux is reduced as part of a carbon limitation response [ 6- 13].
creC encodes for a sensor kinase that is believed to cross-regulate the phosphate limitation response in conjunction with PhoR [70].
Biochemical data also supports this perceived nitrogen limitation response, with selective degradation of the nitrogen-containing chlorophyll- a pigment [ 7, 15].
Herein, we summarise multiple-resource limitation responses in plant communities using a dataset of 641 studies that applied factorial addition of nitrogen (N) and phosphorus (P) in freshwater, marine and terrestrial systems.
High Fe concentrations can lead to the precipitation of Pi thus aggravating P limitation responses.
Postprandial and ultimately fasting glucose levels become abnormal as a limitation in insulin response is reached.
Indeed, several studies showed that experiments conducted on mussels at atmospheric pressure lead to a global increase of stress parameters (lipid peroxidation, anti-oxidant enzymes activity, DNA damage) and to a limitation of stress response capacity [ 14, 23, 102].
A limitation is the 35% response rate which may limit the representativeness of the findings.
A limitation is that the response was not sufficient to compare individual countries.
