Following osmotic shock in the dark, prominent changes were observed in the intracellular level of ATP and polyphosphates, but little to no changes in the intracellular pH or orthoposphate content. On the other hand, the cultures of Philodina rotifers were established in glass bottles and feeding them with algaes and yeast. Background The genus Dunaliella Class — Chlorophyceae is widely studied for its tolerance to extreme habitat conditions, physiological aspects and many biotechnological applications, such as a source of carotenoids and many other bioactive compounds.

The sudden depletion stress of an essential nutrient stops the growth but increase the lipids’ storage. Uptake and release of ship-borne ballast water is a major factor contributing to introductions of aquatic phytoplankton and invasive macroinvertebrates.

The two algal extracts showed interesting antimicrobial properties, which mostly inhibited the growth of isolated S.

ROS and calcium signaling mediated pathways involved in stress responses of the marine microalgae Dunaliella salina to enhanced UV-B radiation. Dynamic filtration was used to moderate the impact of fouling. In the present study, manipulation of carbon flux into fatty acid biosynthesis pathway in Dunaliella salina was achieved using pGH plasmid harboring AccD and ME genes to enhance lipid content and to improve produced biodiesel quality.

It also underscores the usefulness of automated systems in identification of rare pathogens. On the saina hand, 9,octadecadienoic acid omega-6 and ciseicosenoic acid omega-9 were identified from the species Chroomonas sp.

The 51 Cr was used as an indicator to measure the assimilation efficiency of fore-aged silver carp for radiocarbon. Then, accumulations of Ru in Artemia by the ingestion of each diet Dunaliella contaminated with Ru in each water, were investigated and compared with those from each water.

Okadaic acid OAwhich is produced by several dinoflagellate species, is a phycotoxin known to induce a decrease of biomass production in phytoplankton. Besides their self-renewing ability and their potential to differentiate into all cell types in a human body, they arouse a great interest in scientific world by being far from the ethical concerns regarding their embryonic counterparts and their unique feature of being patient-specific in prospective cell therapies.

Bioresource Technology, 99 17— Manganese dioxide Ammonium chloride Alkaline dry cell batteries contain: Chlorophyceae aisladas de lagunas hipersalinas de Venezuela. This systematic approach could generate a blueprint model that is composed of only what it needs, which could make it possible to efficiently control and optimize the process.

The high amount of lipids produced suggests that D. The study aimed to investigate the effects of enriched growth media and cultivation time on nutritional composition of Nannochloropsis salina biomass, with a focus on eicosapentaenoic acid EPA. Despite the benefit of using R.

Differences total carotenoids by cell between treatments were significant.

algae dunaliella salina: Topics by

It was least in sulfate, and increased progressively in chloride, acetate and carbonate in that order. Isolation and characterization of Dunaliella salina from Thailand. Cytotoxicity effects of water dispersible oxidized multiwalled carbon nanotubes on marine alga, Dunaliella tertiolecta.

Carotenoids affect proliferation of salna prostate cancer cells. In the present study, we cloned a 5′ franking region of 1.

Scenedesmus adapted to air at pH 9. On the other hand, 9,octadecadienoic acid omega-6 and ciseicosenoic acid omega-9 were identified from the species Chroomonas sp. The role of ROS and calcium signaling in the D. Under stress conditions dunaliella cells produce more carotenoids.

Steam explosion and dynamic membrane filtration were used as unit operations.

Proliedades are a promising biofuels feedstock, theoretically yielding concentrations of triacylglycerides TAGs per unit area that are far higher than traditional feedstocks due to their rapid growth. The algae growth rate in winter conditions in Denmark was slow, but results revealed that large Neste trabalho cultivaram-se D. The present study aimed to establish an efficient genetic transformation system in the green microalgae Dunaliella tertiolecta using the A.

Throughout the exponential growth period the UV-A irradiated cultures showed enhanced carotenoid accumulation, mostly as beta-carotene. It was not possible to calculate EC50 for 15 nm citrate gold nanoparticles, as they were non-toxic at all concentrations tested. Photosynthetic activity seems to be unaltered under short-term exposition to Cd and chronic exposure to natural metal-rich water, probably due to an increase in the synthesis of structural photosynthetic components preserving their functional integrity.

Two possibilities were evaluated: The highest carotenoid contents per cell were obtained at 2M NaCl in both taxa. Our simulation approach is an easy method for evaluating the cell-cell prkpiedades properties of cells.

Dunaliella is particularly advantageous as a feedstock because it is currently commercially mass cultured, thrives in salt water, and has no cell wall. Both phytosterols from microalga Dunaniella tertiolecta and dietary supplementation with n-3 polyunsaturated fatty acids PUFA influence cell proliferation and cytokine release during inflammation.

The Austrian industry is interested in applying this technique to drives, thermal power stations and the miniature fuel cells as replacement dhnaliella batteries in electronic products Notebooks, mobile telephones, etc. Titanium dioxide nanoparticles TiO 2 NPs have been widely employed in industrial applications, thus rising concern about their impact in the aquatic environment.

The proteins are enriched in the oil globules by 6- to fold compared to chloroplast proteins. Expression levels of these proteins changed in response to the stress conditions, which suggests that they may be involved in the maintenance of intracellular osmotic pressure, cellular stress responses, physiological changes in metabolism, continuation of photosynthetic activity and other propieedades of salt stress.
