The effects of various light emitting diode wavelengths and intensities on the microalgae biological wastewater treatment system was studied in this research.
Industrial fermentation of Auxenochlorella protothecoides for production of biodiesel and its application in vehicle diesel engines. Uptake of uranium from sea water by microalgae. In this study; co-cultivatation of filamentous fungus Aspergillus niger and microalgae Chlorella vulgaris to form cell pellets was evaluated under different conditions, including organic carbon source glucose; glycerol; and sodium acetate concentration; initial concentration of fungal spores and microalgal cells and light.
At freshwater microalgae Chlorella vulgaris was found the best phytoremediation potential in its natural environment at pH of 6. The expression level of Hsp70 proteins and their role in the infectious process is worth further investigation. Optimization of biodiesel production from Chlorella protothecoides oil via ultrasound assisted transesterification.
Trebouxiophyceae and Nannochloropsis sp. Using the flue gas from the coke oven, hot stove or power plant for cultivation, the microalgal strain obtained a maximum specific growth rate and lipid production of 0. Universidad de Antioquia; In this work, the mild disintegration of the microalgae Chlorella vulgaris for the release of mciroalgas products has been studied. In the enzymatic hydrolysis process, the pectinase enzyme group was superior for releasing fermentable sugars from carbohydrates in microalgae.
Their low price makes them economical. Some microalgae are naturally flocculated whose cells can be harvested coneo simple sedimentation.

Crude lutein was obtained by extraction with dichloromethane from the microalga after saponification. Therefore, it is difficult to have identical growth rate for the microalgae cells and to keep their continuous growth.
The approach is expected to guide chloroplast isolation from other oleaginous algal species for a variety of uses that benefit from enrichment of chloroplasts, ranging from biochemical analysis microaalgas genomics studies.
This research provides a basic understanding of Pb II toxicity to aquatic organisms. This is the first time to our knowledge that the flocculating agent from C. The biomass and lipid production responses to different media were examined in terms of optical density, cell density, dry biomass, and lipid productivity.
Moreover algae cultivation lets to achieve high biomass concentration. The biomass concentrations of the old and the new C. Synthesis of aminoclay-templated nanoscale zero-valent iron nZVI for efficient harvesting of oleaginous microalgae was demonstrated. Of particular significance, it was observed that the acyl composition of TAGs in Nannochloropsis sp.
The herbicide paraquat PQ is known to cause inhibition of photosynthesis and irreversible damage to photosynthetic organisms through generation of reactive oxygen species in a light-dependent manner. The aim of the present work was to evaluate the feasibility se microalgae cultivation using secondary treated domestic wastewater.
micgoalgas Aluminium significantly increased P Chlorella vulgaris more efficient in different ways. Natural antioxidants, which can replace synthetic ones due to their potential implications for health problems in children, have gained significant popularity. Full Text Available Microalgae produce a wide range of lipid compounds of potential commercial interest.
The highest growth was in the Synechococcus farm, followed by Chlorella and Anabaena.

Cultivation conditions temperature, pH, light, nutrient quantity and quality, salinity, aerating are the major factors that influence photosynthesis activity and behaviour of the microalgae growth rate.
To improve nutrients removal from real centrate wastewater and enhance the microalgae biomass production, cultivation of Chlorella vulgaris in coneo and a pilot-scale photobioreactor with waste glycerol was studied. Small-scale cultivation tests 50 l with Cd-resistant cells of Chlorella vulgaris have shown that approx. Nitrogen had a major effect in the biomass concentration of C.
The results suggest that lipid microapgas of Chlorella species has significant inhibitory activity on P. The aim of the present study was to evaluate the in vitro cytotoxic effect of Nuevo Leon regional Chlorella sorokiniana Chlorellales: Total lipid contents ranged from 0.
This study aims to examine growth and lipid production by various isolates of icroalgae using different growth media and lipid extraction techniques. Hence, changes in the cellular HNE content upon herbicide treatment inducing lipid oxidative stress and alterations in cellular growth rate of C. Because this microalgae is freshwater, it may find application in inland or in liquid radioactive waste from nuclear facilities. The results also showed that the growth potential, lipid production and fatty acid composition of the microalgal strain were dependent on the composition of the flue gas and on the operating strategy deployed.
In the subchronic study, rats consumed feed containing 0, 25, 50, orppm WAP for days. These organisms were cultivated on two media: Microalgae were studied as function bioaccumulators of selenium Se for kicroalgas and feed supplement. Universidad Jorge Tadeo Lozano; The CO 2 utilization efficiencies of Chlorella sp.
Extraction yields and fatty acid profiles from freeze-dried Chlorella vulgaris by microwave pretreatment followed by supercritical carbon dioxide MW-SCCO2 extraction were compared with those obtained by supercritical carbon dioxide extraction alone SCCO2.
Meanwhile, a significant increase in amino acid miicroalgas organic Se content was also detected in the microalgae.
Salt-stimulation of caesium accumulation in the euryhaline green microalga Chlorella salina: The lab study was performed to observe the Pb II exposure induced changes.
