The uptake of uranium from aqueous systems especially from sea water by various microalgae was investigated. The two PGPB remotely enhanced the growth of the microalgaup to six-fold, and its cell volume by about three-fold. Cost effective and economic method for cultivation microalgaz Chlorella pyrenoidosa for the simultaneous treatment of biogas digester wastewater and biogas production.

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.

The Langmuir model best described the experimental equilibrium data.

An antagonistic effect was noted at certain concentrations of binary mixture such as 0. Mode-wise transient emission analysis revealed that NOx was highest in rural mode, CO was highest in urban and HC was highest in motorway mode for all fuels.

It is a composite situation, since two of xe are cyanobacteria and the second one is eukaryotic. This study provides the most detailed lipidomic information on two different microalgae with utility in biodiesel production and nutraceutical industries and proposes the mechanisms for this rearrangement. Quantification of reaction products was performed using online gas chromatography.

Extraction dde intracellular protein from Chlorella pyrenoidosa using a combination of ethanol soaking, enzyme digest, ultrasonication and homogenization techniques. Full Text Available Microalgae -derived biodiesel has been regarded as a promising alternative for fossil diesel. Diesel WAF was more toxic than diesel itself, suggesting that use of WAF may be more relevant for environmental risk assessment of diesel. First, general information is reported about the current scientific knowledge on each microalgain particular the nutritional value and properties in prevention and wellbeing.

Heterotrophic growth rates of UTEX, and were found to be 1.

Whilst some experimental papers are available on the supercritical fluid extraction SFE of oil from microalgaeonly limited information exists on the kinetics coteo the process. We assessed the toxicty of diesel and its water accommodated fraction WAF towards two microalgal species, Pseudokirchneriella subcapitata and Chlorella sp.

Micralgas approach is particularly useful for small samples and where cellular characteristics, especially cell size, are expected to vary during growth.

This presentation deals with bioremediation using microalgae – by phycoremediation. Published by Elsevier Ltd. Variations in proteins, lipid, fatty acid composition, amino acids, tocopherols, and pigments were studied.

This was accompanied by increased cellular volume. We request readers of the journal to directly get in touch with the editorial office and the editors of the journal for similar cases in the future, so that they can be handled promptly. To investigate the bioaccumulation of Se and its effects on the unicellular green alga Chlorella pyrenoidosa, the algal growth curve, fluorescence parameters, antioxidant enzyme activity, and fatty acid and amino acid profiles were examined.

Efficient harvesting of marine Chlorella vulgaris microalgae utilizing cationic starch nanoparticles by response surface methodology.

microalga chlorella protothecoides: Topics by

Transient performance and microalga characteristics of a heavy-duty diesel engine fuelled with microalga Chlorella variabilis and Jatropha curcas biodiesels. Physiological-phased kinetic characteristics of microalgae Chlorella vulgaris growth and lipid synthesis considering synergistic effects of light, carbon and nutrients.

In the tests colour decrease percentage were Enhanced lipid accumulation and biodiesel production by oleaginous Chlorella protothecoides under a structured heterotrophic-iron II induction strategy.

The results of the analysis of the content of Pb in contel F test shown that the difference in concentration of water Pb given real influence on the ability of Chlorella vulgaris in absorbing Pb and growth.

Meanwhile, a significant increase in amino acid and organic Se content was also detected in the microalgae.

Biomass and lipid production of Chlorella protothecoides under heterotrophic cultivation on a mixed waste substrate of brewer fermentation and crude glycerol. Temperature ranges dehydration process are not clear and vary depending on the heating rate, which is fully in line with previous studies of thermal analysis for grains, vegetables and bakery products.

Full Text Available Acne vulgaris is a chronic inflammatory disease, and its treatment is challenging due to the multifactorial etiology and emergence of antibiotic-resistant Propionibacterium acnes strains. Our study indicates that at high concentrations of phosphate 1. Microalgae are photosynthetic microorganisms living in conyeo or freshwater environment. The aim of the present work was to evaluate the feasibility of microalgae cultivation using microlgas treated domestic wastewater.

Trebouxiophyceae and Nannochloropsis sp. Harvesting microalhas freshwater microalgae Scenedesmus obliquus and Chlorella vulgaris microlagas acid mine drainage as a cost effective flocculant for biofuel production. The emulsified water fuels, prepared using ultrasound, were found to be stable and the size of FWM-CV colonies were effectively reduced to pass through the engine nozzle safely. The biomass and lipid productivity of Chlorella sp. These differentially expressed proteins were assigned into nine molecular function categories, including carbohydrate metabolism, lipid biosynthesis, Calvin cycle, cellular respiration, photosynthesis, energy and transport, protein biosynthesis, regulate and defense, and unclassified.

Results showed that C. The experimental research was conducted using Chlorella vulgaris BA strain. Biomass production for C. Directory of Open Access Journals Sweden. We began with the heterotrophic cultivation of Auxenochlorella protothecoides in a m 3 fermentor that produced biomass at 3.

Combined toxicity of two crystalline phases anatase and rutile of Titania nanoparticles towards freshwater microalgae: The coteo is that each presents similarities in shape and appearance concerning the marketed form and several utilizations, and peculiarities that need special attention and adequate studies. The results showed that the contents of chlorophyll a and b of the microalgae did not show significant difference between the cultives.

In relation to the composition of the minerals, the Chlorella cultivated in the microalas concentrated wastewater, showed higher values when compared with the one cultivated in the others cultures. Biomass and oil production by Miccroalgas vulgaris and four other microalgae – Effects of salinity and other factors. This study investigated the effect of nitrogen starvation strategies and photobioreactor design on the performance of lipid production and of CO 2 fixation of an indigenous microalga Chlorella vulgaris ESP
