Impact of phosphate concentration on docosahexaenoic acid production and related enzyme activities in fermentation of Schizochytrium sp.
Abstract:Docosahexaenoic acid (DHA) is an important and widely used infant food additive. In this study, the effects of phosphate concentration on lipid and especially DHA synthesis in the oleaginous fungi Schizochytrium sp. HX-308 have been investigated in batch cultures. The maximum DHA yield (8.9 g/L) and DHA productivity (148.3 mg/L h) in 0.1 g/L KH2PO4 concentration were higher than the DHA yield (6.2 g/L) and DHA productivity (86.1 mg/L h) in 4 g/L KH2PO4 concentration. Furthermore, differences in related enzyme activities (malic enzyme, glucose-6-phosphate dehydrogenase and NAD+-isocitrate dehydrogenase) between phosphate-sufficient and phosphate-limitation conditions were assayed. The results showed that the phosphate-limitation condition could maintain higher activities of malic enzyme and glucose-6-phosphate dehydrogenase in addition to lower activity of NAD+-isocitrate dehydrogenase. In addition, glucose-6-phosphate dehydrogenase might be the main supplier of NADPH at the early stage of fermentation while malic enzyme might be the provider at the late stage. This information might explain the regulation mechanism of phosphate limitation for lipid production and be useful for further DHA production enhancement.
Sorption of organic phosphates and its effects on aggregation of hematite nanoparticles in monovalent and bivalent solutions
Abstract:Sorption of organic phosphates–myo-inositol hexakisphosphate (IHP) and glycerol phosphate (GP) and its effects on the early stage of hematite aggregation kinetics were investigated at different pH and electrolyte composition. KH2PO4 (KP) was taken as an inorganic P source for comparison. Results indicated that for all types of P, the sorption amounts decreased with increasing solution pH. Sorption amount of IHP was almost two times that of KP, while those of GP and KP were close. Both organic P and inorganic P interacted with hematite via ligand exchange through their phosphate groups, which conveyed negative charges to mineral surface and significantly decreased the zeta potential of hematite. In Na+ solution, critical coagulation concentrations (CCCs) of hematite suspensions increased with increasing P concentration and followed the order of KP < GP < IHP at pH 5.5. Compared with KP, the organic P could more effectively stabilize the hematite suspension not only through increasing the negative charges and electrostatic repulsive force, but also through steric repulsion between P-sorbed hematite nanoparticles. When the pH was increased from 5.5 to 10.0, the CCCs of the hematite suspensions with GP and IHP decreased mainly because of the great reductions in organic P sorption amounts and consequent decreases in electrostatic and steric repulsive forces. However, enhanced aggregation was observed in the presence of IHP at pH 4.5 and above in low Ca2+ solutions. The precipitation of calcium phytate formed net-like structure, which served as bridges to bind hematite nanoparticles and resulted in enhanced aggregation. These results have important implications for assessing the fate and transport of organic P and hematite nanoparticles in soil and aquatic environments.
