In this research, the fatty acids of isolated microalgae were extracted by some technologies such as maceration, Soxhlet, ultrasonic-assisted extraction and supercritical fluid extraction; and analyzed for biodiesel production using GC-MS.

Analysis using the Kyoto encyclopedia of genes and genomes and gene ontology annotation showed that malic enzyme, acyltransferase, and ACP were key metabolic checkpoints found to modulate lipid accumulation in C.

The immobilized microalgae score were The results showed that ultrasound-assisted transesterification may be an alternative and cost effective way to produce biodiesel efficiently.

In the subchronic study, rats consumed feed containing 0, 25, 50, orppm WAP for days. The results indicated that UV-B caused a decrease in cell density in cultures irradiated for the first time 1st stage, with a significant increment P Coagulant effect of ferric chloride for separation of biomass from the microalgae Chlorella sp.

However, the growth of Synechococcus required 10 days to achieve this increase that represents a negative indicator of the adoption of this type of microalgae in this media to meet the desired aims. In the current paper, the unicellular green microalga Chlorella kessleri was used to study the effect of two herbicides S-metolachlor and terbuthylazine and hydrogen peroxide H 2 O 2 on oxidative stress induction, HNE formation, chlorophyll content and the cell growth.

Comparison of an environmental strain with infectious strains resulted in the identification of 51 differentially expressed proteins related to carbohydrate metabolism, energy production and protein translation. Toxicity of diesel water accommodated fraction toward microalgaePseudokirchneriella subcapitata and Chlorella sp.


In these cases indirect methods must be used, inducing measurement artefacts which vary in severity with the cell type and conditions employed. There was significant increase pScenedesmus under only visible light pScenedesmus species, which could easily be correlated with the uptake of the NPs.

Compared to the growth of C. Heavy metal sorption by microalgae. The greatest increase in biomass was observed when LR was applied ed a suspension of microalga Chlorella sorokiniana with a beam of 5 cm diameter for a time of 10, 15 and 20 minutes.

The relevance of cotneo results to the possible use of C. L-1 em 22 dias de cultivo. The effect of indoleacetic acid addition to microaglas culture prior to immobilization of microorganisms in alginate beads partially imitated the effect of A. Mis-shaped chloroplasts, lack of nucleus, and starch-pyrenoid complex were noted in binary. 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 to genomics studies.

EE – Microbiology, Virology Impact factor: Although other microalgae such as C. This article studies the influence of laser radiation on the growth of micro-algal biomass of Chlorella sorokiniana.

microalga chlorella protothecoides: Topics by

FS was isolated and identified from the culture of Chlorella zofingiensis. Moreover, the lipid content was significantly positively related to the concentration of hydroxyl functional groups in spite of algal strains or growth phases.

Finally, from the 32 fatty acids analyzed for both neutral lipids NL and polar lipids PL fractions, it is clear that the water treatment greatly improves NL-to-PL ratio for the four standard methods assessed. Oxy-fuel combustion characteristics and kinetics of microalgae Chlorella vulgaris by thermogravimetric analysis. The comparison of the activation energy values obtained by the methods and those found in the literature for other microalgae was satisfactory. The combination of PEF with temperatures from.


Conteo de microalgas

This research was aimed at evaluating the composition of minerals, as well as, determining the content of chlorophyll a and b from the microalgae Chlorella vulgaris cultivated in hydroponic wastewater in three different concentrations compared with the control cultive.

For evaluation of the samples was used HPGe gamma spectrometer measurement time of the microalas Samples of this microalgae previously cultivated with nourishing fertilizer under photoperiods of light and darkness were taken to test the microalgae Chlorella sp. The surface properties like particle size, the degree of hydrophobicity, and the total concentration of functional groups increased while net surface zeta potential decreased.

Growth curves of two species were confirmed in the double system bubble column photo-bioreactor, and the second growth of yeast was observed during h of mixed culture. Utilization of carbon dioxide in industrial flue gases for the cultivation of microalga Chlorella sp. Harvesting involves nearly thirty percent of total production cost of microalgae that needs cotneo be done efficiently.

This microalgsa demonstrated contei Chlorella sp. In the tests colour decrease percentage were Exposure Pb ion in Chlorella vulgaris for 7 days. We propose that coimmobilization of microalgae and plant-growth-promoting bacteria is an effective means of increasing microalgal populations within confined environments.

The composition of biogas consists mainly of methane and carbon dioxide.
