Seawater samples were collected from the coastal area along the Lebanese coast. The samples were fertilized using Guillards F/2 medium and cultured in 2 L flasks. Out of five promising blooms, three were selected and cultured in 70 L cylinders and in 300 L raceway ponds under greenhouse conditions. A culture of Chlorella "marine" was used as reference. The growth dynamics were determined...
Seawater samples were collected from various locations along the Lebanese coast. Four unilagal isolates were acquired using streaking and serial dilution methods. The four isolates were cultured in 20 L flat photo-bioreactors containing seawater fertilized with Guillards F/2 medium. The growth dynamics, dry matter yield, lipid content, fatty acid profile and potential biodiesel yield were determined...
Influx of sewage into surface water results in nutrient enrichment and consequently leads to algal bloom and voluminous organic sludge production in urban areas as in case of Bangalore. The lack of utilities of algae and resulting sludge has lead to anoxia and GHG emissions. Environmental friendly ways of sludge and algal biomass utilities as well as disposal are scant. Testing for biofuel and thermal...
The aim of this work is to present the development of a computer aided multilevel modeling network for the systematic design and analysis of processes employing lipid technologies. This is achieved by decomposing the problem into four levels of modeling: i) pure component property modeling and a lipid-database of collected experimental data from industry and generated data from validated predictive...
Some filamentous fungi were screened as potential oleaginous microorganisms for production of microbial lipid. The results showed that filamentous fungus Strain SCIM04 displayed the most potential ability in producing microbial lipid, the lipid content of cells reached 50.93%, and the lipid yield was 8.4±0.42 g /L. Furthermore, the components profile of the lipid were analyzed. The results revealed...
To screen potential oleaginous microorganisms for production of microbial lipid, thirty-one yeast strains from forest soils collected from Hunan Province, China, were tested for their potentiality to produce microbial lipid, and fourteen potential strains were further screened. The results showed that yeast strain SCIM 2.012 displayed the most potential ability in producing microbial lipid, the lipid...
Micro-algae have the potential to produce enough bio-fuels to meet the current US fuel demands. In order to achieve this potential, photo-bioreactors (PBRs) need to be developed that are efficient, scalable, and affordable. Models are an analytical tool that can be used to evaluate various PBRs. In this article, a dynamic model is developed for growing micro-algae in a vertical flat panel photo-bioreactor...
Oleaginous yeasts can use different kinds of residues as nutrients. Their biomass contains a significant fraction (>20%) of lipids, that can be used as feedstock for biodiesel production. Lipomyces starkeyi were able to survive and proliferate in the presence of olive mill wastewater (OMWW), without external organic supplement, in spite of the antimicrobial activity of their phenolic components...
