Studies have demonstrated that photosynthetic limitations and starch degradation are responses to stress; however, the relationship between two is seldom described in detail. In this article, effects of salt stress on photosynthesis, levels NADPH total RNA, content activities glucose-6-phosphate dehydrogenase (G6PDH) ribulose-5-phosphate kinase (RPK) were evaluated. thalli underwent treatments, cyclic electron flow through PSI showed greater tolerance than PSII. Even though linear was...
Phaeodactylum tricornutum Bohlin is an ideal model diatom; its complete genome known and it important economic microalgae. Although silicon not required in laboratory factory culture of this species, previous studies have shown that starvation can lead to differential expression miRNAs. The role plays P. growth nature poorly understood. In study, we compared the rate starved with normal cultured cells under different conditions. Pigment analysis, photosynthesis measurement, lipid analysis...
Under high light (HL) stress, astaxanthin-accumulating Haematococcus pluvialis and β-carotene-accumulating Dunaliella salina showed different responsive patterns. To elucidate cellular-regulating strategies photosynthetically metabolically, thylakoid membrane proteins in H. D. were extracted relatively quantified after 0 h, 24 h 48 of HL stress. Proteomic analysis that three subunits the cytochrome b6/f complex greatly reduced under stress pluvialis, while they increased salina....
Abstract Background Numerous studies have shown that stress induction and genetic engineering can effectively increase lipid accumulation, but lead to a decrease of growth in the majority microalgae. We previously found elevated CO 2 concentration increased productivity as well Phaeodactylum tricornutum , along with an enhancement oxidative pentose phosphate pathway (OPPP) activity. The purpose this work directed toward verification critical role glucose-6-phosphate dehydrogenase (G6PDH),...
Abstract Macroalgal blooms (green tides) are occurring more frequently in many regions of the world, leading to significant impacts on marine ecology and economies. Although studies hypotheses have been proposed, exact mechanism green tide formation remains unclear. The world's largest tides recur Yellow Sea this area is representative for studying origin formation. We conducted a meta‐analysis related associated their Rapid industrialization/urbanization environmental protection actions...
Untreated printing and dyeing wastewater can significantly harm the environment ecosystem upon which humans rely for survival. Ulva linza (U. linza) is a green alga, one of the...
Summary The development of microalgae on an industrial scale largely depends the economic feasibility mass production. High light induces productive suspensions during cultivation in a tubular photobioreactor. Herein, we report that high light, which inhibited growth C hlorella sorokiniana under autotrophic conditions, enhanced this alga presence acetate. We compared pigments, proteomics and metabolic flux ratio . cultivated ( HL ) low LL Our results showed induced synthesis xanthophyll...
Both biomass dominated green vegetative cells (GV) and astaxanthin-dominated orange resting (OR) affect the final astaxanthin yield in industry. Examination of Haematococcus pluvialis revealed that OR greatly varied from GV at both cellular subcellular levels. In particular, thylakoid membranes were disassembled fragmented. Furthermore, conserved most photosynthetic pigments, with elevated concentrations violaxanthin, antheraxanthin, neoxanthin. Notably, moderate photosynthesis was detected...
The photosynthetic performance of the desiccation‐tolerant, intertidal macro‐algae Ulva prolifera was significantly affected by sorbitol‐induced osmotic stress. Our results showed that activity decreased with increases in sorbitol concentration. Although partial both photosystem I ( PS ) and II able to recover after 30 min rehydration, more rapidly than . At 4 M concentration, almost 0 while still at about one third normal levels. Following prolonged treatment 1 2 sorbitol, slowly,...
Abstract Background Diatoms contribute 20% of the global primary production and are adaptable in dynamic environments. always bloom earlier annual phytoplankton succession instead dinoflagellates. However, how diatoms acclimate to a environment, especially under changing light conditions, remains unclear. Results We compared growth photosynthesis fluctuating conditions red tide diatom Skeletonema costatum , dinoflagellate Amphidinium carterae Prorocentrum donghaiense Karenia mikimotoi model...
Cyanobacteria are rich in phytochemicals, which have beneficial impacts on the prevention of many diseases. This study aimed to comprehensively characterize phytochemicals and evaluate multifunctional bioactivities ethanolic extract cyanobacterium Leptolyngbya sp. KC45. Results found that mainly contained chlorophylls, carotenoids, phenolics, flavonoids. Through LC-ESI-QTOF-MS/MS analysis, 38 phenolic compounds with promising were discovered, a higher diversity flavonoids was among...
This study investigates the development of dual-substrate mixotrophy strategy to cultivate microalga Haematococcus lacustris for astaxanthin production. The influence different concentrations acetate and pyruvate on biomass productivity was first assessed individually, then both substrates were used together improve growth in green phase accumulation red phase. results showed that dual-substrates significantly increased during up 2-fold compared phototrophic controls. Furthermore,...
For plants and algae, exposure to high light levels is deleterious their photosynthetic machineries. It also can accelerate water evaporation thus potentially lead drought stress. Most organisms protect themselves against caused photodamages by xanthophyll cycle-dependent thermal energy dissipation. generally accepted that activates cycle. However, the relationship between cycle stress remains ambiguous. Herein, Ulva pertusa (Chlorophyta), a representative perennial intertidal macro-algae...
Iron is a limiting factor that controls the phytoplankton biomass in modern ocean, and iron fertilization of ocean could lead to blooms dominated by diatoms. Thus, plays an important role controlling distribution In this study, we measured growth rate photosynthetic activity model diatom Phaeodactylum tricornutum cultured under different concentrations found it grew more rapidly had much higher efficiency concentrations. order explore unique mechanism response diatoms iron, proteomic...
