The results provided possible applications of HII cultivation strategy in other microalgal mixroalgas and new possibilities in developing genetic and metabolic engineering microalgae for desirable lipid productivity. Published by Elsevier Ltd. The effects of growth phase on the lipid content and surface properties micraolgas oleaginous microalgae Botryococcus sp. For this purpose, it was cultivated in 0.

In both algae the overall fatty acid profiles of the polar lipid classes were largely unaffected by N-deprivation, suggesting a specific FA profile for each compartment is maintained to enable continued function despite considerable reductions in the amount of these lipids. Compared with original biomasses, the sorption capacity of microalgal by-products changes only insignificantly.

These results dde a basis for further studies on the refinery process using oleaginous microalgae for biofuel production. A 2-L photo-bio-reactor was adapted from a commercial calorimeter used previously to study heterotrophic.

However, these species differ significantly in their photoautotrophic and heterotrophic characteristics. The highest methyl ester production was obtained under the conditions of 9: Results of Alpha linoleic acid C Diesel WAF was more toxic than diesel itself, suggesting that use of WAF may be more relevant for environmental risk assessment of diesel.

Mass methods were used for the extraction of intracellular protein from microalgae with biological, mechanical and chemical approaches.

Cultivation carried out for 7 days xonteo different percent volume of tofu liquid waste showed that the more volume of tofu liquid waste make them longer process decipherment of polymer compounds in the waste, that’s make the growth rate of Chlorella sp. It occurs in hypersaline environment with tolerance 0. Lutein is a pigment generally extracted from marigold flowers. Our results show that CO 2 utilization efficiency can be markedly increased by intermittent CO 2 aeration and alkaline media as a CO 2 -capturing strategy for alkali-tolerant microalga cultivation.

The results also showed that an congeo carbon source was required to sustain the growth of fungi and form the cell pellets. Production of HNE was detected in this study for the first time in the cells of unicellular green algae using the antibody specific for the HNE-histidine adducts revealing the HNE-histidine adducts even in untreated, control C.

Chlorella regularisChlamydomonas -Scenedesmus – The reality is that each presents similarities in shape and appearance concerning the marketed microalgaas and several utilizations, and peculiarities that need special attention and adequate studies. Regarding the antioxidant activity, macroalgae showed again higher values than microalgae.

Ability of an alkali-tolerant mutant strain of the microalga Chlorella sp. The implications of the experimental design utilized and the potential utility of this type of approach are discussed.

As for 28 d treatments, the three genes displayed similar inhibitory trend. Optimization microaalgas biodiesel production from Chlorella protothecoides oil via ultrasound assisted transesterification. In the study, These organisms were cultivated on two media: ZVI composite ratio 1. Upon contamination by Scenedesmus sp. Small-scale cultivation tests 50 l with Cd-resistant cells of Chlorella vulgaris have shown that approx.

The effect of co-digestion was evaluated by varying CM to Chlorella sp.

microalga chlorella protothecoides: Topics by

The carbon dioxide formed during fermentation and after combustion of methane for energy production, is planned to be used as a carbon source in the cultivation of Chlorella sorokiniana for photoautotrophic biomass production.

However, neither cell concentration nor optical density correlates well to biomass when growth conditions vary.

Biodiesel, also known as fatty acid methyl or ethyl ester, has emerged as a substitute for diesel because of similar fuel properties. Kinetics of Chlorella protothecoides microalgal oil using base catalyst. Biodiesel is a renewable alternative to petro-diesel used in compression ignition CI engine.

L-1 em 22 dias de cultivo. Bioremoval of the azo dye Congo Red by the microalga Chlorella vulgaris.

micfoalgas Full Text Available A dynamic mathematical model is presented to describe the symbiotic growth of the microalgae Chlorella sp. Due to its unstable supply and increasing price, fish meal is becoming more expensive and its availability is expected to face significant challenges in the near future.

Results of the observations show: However, the taxonomy of Chlorella -like organisms is easily confused. Se expusieron cultivos de Chlorella sp. The proposed control of quality is based on microscopic analysis of the morphologic characteristics.

In each case, survival and growth, dry weight, internal aluminium content of the sample, antibacterial properties, the content of fatty acids accumulated in the algae and secreted into the culture medium in the logarithmic growth phase were studied.
