The Green Microalga Chlorella saccharophila as a Suitable Source of Oil for Biodiesel Production.

Summary of "The Green Microalga Chlorella saccharophila as a Suitable Source of Oil for Biodiesel Production."

The aim of this study was to investigate the potential of the green microalga Chlorella saccharophila as a source of oil for biodiesel production. We evaluated for the first time, the effect of salinity and/or nitrogen depletion (ND) on cell growth, lipid accumulation and lipid profile in this microalga. The fatty acid methyl esters (FAME) identified for C. saccharophila in this study consisted of C-16:0, C-18:0, C-18:1 cis, and C-18:1 trans. Among these, C-18:1 (indicator of biodiesel quality) was the main FAME found, representing approximately 76 and 80% of total FAME under normal and ND growing conditions, respectively. Under a normal growing condition this microalga showed 154.63 mg l(-1) d(-1), 63.33 mg l(-1) d(-1), and 103.73 mg l(-1) of biomass productivity, lipid productivity, and FAME yield, respectively. The higher biomass productivity (159.58 mg l(-1) d(-1)), lipid productivity (99.33 mg l(-1) d(-1)), and FAME yield (315.53 mg l(-1)) were obtained under the ND treatment. In comparison to other related studies, our results suggest that C. saccharophila can be considered as a suitable source of oil for biodiesel production.

Performance assessment of biofuel production in an algae-based remediation system.

The production of biofuel from microalgae has been an area of great interest as microalgae have higher productivities than land plants, and certain species have high lipid constituents which are the m...

Simultaneous production of triacylglycerol and high-value carotenoids by the astaxanthin-producing oleaginous green microalga Chlorella zofingiensis.

The production of lipids and astaxanthin, a high-value carotenoid, by Chlorella zofingiensis was investigated under different culture conditions. Comparative analysis revealed a good correlation betwe...

Effect of nitrogen regime on microalgal lipid production during mixotrophic growth with glycerol.

Mixotrophic growth of microalgae to boost lipid production is currently under active investigation. Such a process could be of practical importance if a cheap source of organic carbon, such as waste g...

Medical and Biotech [MESH] Definitions

Nonmotile unicellular green algae potentially valuable as a source of high-grade protein and B-complex vitamins.

The dry cells of any suitable strain of SACCHAROMYCES CEREVISIAE or CANDIDA. It can be obtained as a by-product from the brewing of beer or by growing on media not suitable for beer production. Dried yeast serves as a source of protein and VITAMIN B COMPLEX.

A species of green microalgae in the family Chlorellaceae. It is used as a model organism for PHOTOSYNTHESIS, and as a food supplement (DIETARY SUPPLEMENTS).

Processes by which phototrophic organisms use sunlight as their primary energy source. Contrasts with chemotrophic processes which do not depend on light and function in deriving energy from exogenous chemical sources. Photoautotrophy (or photolithotrophy) is the ability to use sunlight as energy to fix inorganic nutrients to be used for other organic requirements. Photoautotrophs include all green plants, GREEN ALGAE; CYANOBACTERIA, and green and PURPLE SULFUR BACTERIA. Photoheterotrophs or photoorganotrophs require a supply of organic nutrients for their organic requirements but use sunlight as their primary energy source; examples include certain PURPLE NONSULFUR BACTERIA. Depending on environmental conditions some organisms can switch between different nutritional modes (AUTOTROPHY; HETEROTROPHY; chemotrophy; or phototrophy) to utilize different sources to meet their nutrients and energy requirements.

Algae of the division Chlorophyta, in which the green pigment of CHLOROPHYLL is not masked by other pigments. Green algae have over 7000 species and live in a variety of primarily aquatic habitats. Only about ten percent are marine species, most live in freshwater. They are more closely related to the green vascular land PLANTS than any other group of algae.
