Commercial production of renewable energy feedstocks from microalgae will require reliable and scalable growth systems. Two and one half years of biomass and lipid productivity data were obtained with an industrial-scale outdoor photobioreactor operated in Fort Collins, Colorado (USA). The annualized volumetric growth rates for Nannochloropsis oculata (CCMP 525) and Nannochloropsis salina (CCMP...

background: this study quantified the effect of four popular culture media in a biodiesel production study on the qualitative and quantitative lipid content, dry biomass, and lipid productivity of nannochloropsis oculata. methods: culture of microalgae was done separately in walne, f/2, sato, and tmrl media. in the logarithmic and stationary growth phases, biomass production and lipid accumulat...

Soybean meal has been used in many commercial diets for farm fish; despite this component inducing intestinal inflammation. On the other hand, microalgae have increasingly been used as dietary supplements in fish feed. Nevertheless, the vast quantity of microalgae species means that many remain under- or unstudied, thus limiting wide scale commercial application. In this work, we evaluated the ...

Characterization of the feeding preferences of bivalve larvae would help improving the bivalve aquaculture and hatchery by providing appropriate microalgal diets. However, inaccurate and laborious identification and counting of microalgal species have challenged the selective feeding of bivalves. In the present study, we developed a highly specific and sensitive assay using quantitative polymer...

This short communication reports a pioneering research of using bacteria for simultaneous algal cell disruption and cell wall/membrane utilization. Microalgae are regarded as one of the most promising feedstock that can potentially address the twin challenges of energy security and environmental protection due to their fast growth rate, high lipid content and CO2 biofixation capabilities. Howev...

Physical and chemical properties of biodiesel are influenced by structural features of the fatty acids, such as chain length, degree of unsaturation and branching of the carbon chain. This study investigated if microalgal fatty acid profiles are suitable for biodiesel characterization and species selection through Preference Ranking Organisation Method for Enrichment Evaluation (PROMETHEE) and ...

The objective of this work was to analyze the growth Scenedesmus acutus, Nannochloropsis oculata and Chlorella vulgaris at different temperatures (25, 30 38°C) in order identify changes lipid content, accumulation neutral lipids fatty acids profile. According results obtained, temperature 30°C does not affect microalgae S. N. C. vulgaris; however, there is a greater amount total acutus ...

Nannochloropsis oculata is a unicellular microalgae which vastly found throughout the environment and have been widely studied due to its high productivity of secondary metabolites oil content. It majorly cultured in aquaculture sector as fish feed for industries polyunsaturated fatty acids. This work aims study impact salinity oxidative stress on expression carotenoid biosynthesis genes accumu...
