Flow cytometry for biomass estimation is easy to perform, sensitive and offers more comprehensive information than optical density measurements.

Diesel WAF was more toxic than diesel itself, suggesting that use mucroalgas WAF may be more relevant for environmental risk assessment of diesel. In this work, the mild disintegration of the microalgae Chlorella vulgaris for the release of intracellular products has been studied. It is believed that this approach, thanks to the recyclability of aminoclay-nZVI composites, can be applied in a continuous harvesting mode At present, microalgae are presented as an ideal third generation biofuel feedstock because of their rapid growth rate.

The freshwater microalgaeChlorella regularis, Scenedesmus bijuga, Scenedesmus chloreloides, Scenedesmus obliquus, Chlamydomonas angulosa, Chlamydomonas reinhardtii, accumulated relatively large amounts of uranium from the solution containing uranium only.

Here, we utilise flow cytometry pulse width data for the estimation of cell density and biomass, using Chlorella vulgaris re Chlamydomonas reinhardtii as model algae and compare it to optical density methods. The optimal mixed culture model of oleaginous yeast Rhodotorula glutinis and microalga Chlorella vulgaris was confirmed to enhance lipid production. The results showed that the highest Chlorella sp. In particular, BB extract presented the highest extraction In a freshwater ecosystem, Chlorella and Scenedesmus are among the most commonly found algal species frequently used to study the effects of metal oxide nanoparticles.

How to cite this article. The results showed that throughout the growth phases, the lipid content of microalgae increased. Ecotoxicity of Ag-nanoparticles on two microalgaeChlorella vulgaris and Dunaliella tertiolecta. Moreover, the lipid content was significantly positively cconteo to the concentration of hydroxyl functional groups in spite of algal strains or growth phases. The aim of this study was to determine the effectiveness of biomass growth in laboratory condition.

Autotrophic micralgas productivity with the two-reactor association, 0. The potential of C.

The amount of uranium absorbed differed markedly with different species of marine microalgae. Extracts from Ascophyllum nodosum AN and Bifurcaria bifurcata BB showed the highest antioxidant potential compared to the mircoalgas of the samples.

Full Text Available Microalgae are a group of organisms, which have a significant potential for industrial applications. Chlorella vulgaris is a representative of eukaryotic green microalgae with the highest chlorophyll content with the appearance in fresh water.

Extraction of intracellular protein from Chlorella pyrenoidosa using a combination of ethanol microalhas, enzyme digest, ultrasonication and homogenization techniques.

Pulsed Electric Field PEF is currently discussed as promising technology for mild and scalable cell disintegration of microalgae. Chlorella regularisChlamydomonas -Scenedesmus – In particular, the carbohydrates in microalgae make them a candidate for bioethanol feedstock.

Increase in concentrations of diesel or its WAF significantly increased toxicity towards growth, measured in terms of chlorophyll a content in both the algae.

Regarding the antioxidant activity, macroalgae showed again higher values than microalgae. Therefore, feasible alternatives to fish meal are urgently required. The higher colour removal mciroalgas score was that with nutrients at 0. Biomass and oil production by Chlorella vulgaris and four other microalgae – Effects of salinity and other factors. The study confirmed the possibility of the use of the phosphoric shock in the medium to maximize lipids accumulation by the microalgae Chlorella vulgaris.

Cultivation of Chlorella vulgaris in a pilot-scale photobioreactor using real centrate wastewater with waste glycerol for improving microalgae biomass production and wastewater nutrients removal.

These organisms were cultivated on two media: Photosystem II-cyclic electron flow powers exceptional photoprotection and record growth in the microalga Chlorella ohadii. The acetone method with the water treatment led to the highest extraction level of TAG with Full Text Available While photosynthetic microalgaesuch as Chlorellaserve as feedstocks for nutritional oils and biofuels, heterotrophic cultivation can augment growth rates, support high cell densities, and increase triacylglycerol TAG micrlalgas content.

A real-time PCR assay suggests the changes in transcript abundances of three photosynthetic-related genes. Full Text Available A dynamic mathematical model is presented to describe the symbiotic growth of the microalgae Chlorella sp.
