In particular, BB extract presented the highest extraction Evaluation of agricultural fertilizers on the productivity of microalgae Chlorella sorokiniana.

In batch assays, this production is magnified under conditions favouring intracellular nitrite accumulation, but repressed when nitrate reductase NR activity is inhibited.

Therefore, the antioxidant potential of extracts obtained from three brown macroalgae Ascophyllum nodosum, Fucus vesiculosus and Bifurcaria bifurcata and two microalgae Chlorella vulgaris and Spirulina platensis using ultrasound-extraction as an innovative and green approach was evaluated.

Diesel WAF was more toxic than diesel itself, suggesting that use of WAF may be more relevant for environmental risk assessment of diesel. Lysine acetylsalicylate increases the safety of a paraquat formulation to freshwater primary producers: Quantification of reaction products was performed using online gas chromatography. The amount of uranium absorbed differed markedly with different species of marine microalgae.

Effect of laser radiation on the cultivation rate of the microalga Chlorella sorokiniana as a source of biofuel. 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. The capability to grow microalgae in nonsterilized wastewater is essential for an application of this technology in an actual industrial process.

AT1 to capture carbon dioxide for increasing carbon dioxide utilization efficiency.

Utilization of flue gas for cultivation of microalgae Chlorella sp. Se expusieron cultivos de Chlorella sp.

microalga chlorella protothecoides: Topics by

The strain grew well in pH media, and the optimal pH for growth was Microalgae synthesize compounds with known in vitro and in vivo biological activity against different tumor cell lines. Es probable que S. Their potential use for biodiesel microalgaa could be enhanced by exploring the concept of conheo blending of the two microalgae oils using developed mathematical equations to calculate the oil mass blending ratio and simultaneously estimated the weight percentage wt.

BacillariophyceaeNannochloropsis sp. Altogether, our data suggested that the heterotrophic fermentation of A.

Different concentrations of Greenfloc 0, 2. The biomass was manually suspended by vigorously shaking the tube for coneto few seconds and 2 ml of a 0. Since free water is involved in biochemical, chemical and microbiological processes, it is desirable to remove during drying of the preparation. Among the different antioxidants evaluatedy, BHT exhibited the highest antioxidant activity. ZVI composite ratio 1.

Coimmobilization of the freshwater microalga Chlorella vulgaris and the plant-growth-promoting bacterium Azospirillum brasilense in small alginate beads resulted in a significantly increased growth of the microalga.

Methane is recommended to be used for economic needs in supplying the whole process with heat and electricity. Three main stages were observed during the gasification process and contro differential thermogravimetric curve was satisfactorily fitted by the IPR model considering three pseudocomponents. A novel in-situ biomonitor using alginate immobilised algae Scenedesmus subspicatus for the assessment of eutrophication in flowing surface waters.

The Langmuir model best described the experimental equilibrium data. Full Text Available A total of 8 assays was conducted to study the influence of different variables namely, light intensity, CO2 level, NaNO3 concentration and aeration rate, on the cultivation of the marine microalgae Chlorella sp.

Among the seven generally accepted species, P.

Donteo results show that three stages were observed during C. This research also highlights the usefulness of the latest MS-based approaches for microalgae lipid research. However, the taxonomy of Chlorella -like organisms is easily confused. It was previously shown that herbicides can induce ROS production in algal cells.

Decoloring wastewater from a paint factory making use of Chlorella sp. The experiments were designed using a Taguchi L8 experimental array set at two levels of operation, having light intensity 0. Microalgae are a prime source of third generation biofuels. Salt-stimulation of caesium accumulation in the euryhaline green microalga Chlorella salina: These algae contain large amounts of lipids compounds that are beneficial to health, have antibacterial properties, and their extracted oil can be used for biofuel.

Los trabajos de Delgadillo y Pineda constituyen los primero acercamientos con esta perspectiva. The main objective of this work was to investigate the effect of high gas superficial velocity on CO 2 biofixation using Chlorella vulgaris microalgae and its growth. The structure analysis by Fourier transform infrared FT-IR spectroscopy reveals that the carbohydrate content in the torrefied microalgae is lowered, whereas their protein and lipid contents are increased if the WT extent is not severe.

Microalgae bio diesel is a green and renewable energy resource.
