To study the acute effect of dietary docosahexaenoic acid (DHA, C22:6) on the expression of adipocyte determination and differentiation-dependent factor 1 (ADD1) mRNA in pig tissues, weaned, crossbred pigs (28 d of age) were fed with either 10% (on as-fed basis) tallow (high stearic acid), soybean oil (high linoleic acid), or high DHA algal oil for 2 d. The plasma and liver DHA reflected the co...

The present study has been undertaken to assess integrated algal harvesting in sewage wastewater for biodiesel feedstock. Chlorella minutissima microalgae are grown in wastewater from local hotel sewage drain and produced biomass is used to produce biodiesel. C. minutissima effectively removes the wastewater nutrients nitrogen and phosphorus with the 99.19% and 96% removal respectively. Content...

The need to replace petroleum fuels with alternatives from renewable and more environmentally sustainable sources is of growing importance. Biomass-derived biofuels have gained considerable attention in this regard, however first generation biofuels from edible crops like corn ethanol or soybean biodiesel have generally fallen out of favor. There is thus great interest in the development of met...

This study includes isolation, purification, and identification of algae from different environmental places (Tigris River and canal around AlJadriah) during February 2008. Nine unialgal cultures were obtainedwhich included 4 species of blue-green algae, 4 species of green algae, and 1 species of diatoms. However, contaminant bacteria and fungi were isolated from 4 of these algal cultures which...

pollutions. Recently, both Persian Gulf and Gulf of Oman are experiencing several types of pollution including oil spills and heavy metal pollutions as well as Harmful Algal Bloom (HAB) caused by biological and environmental changes. Theiroccurrence of the red tide or harmful algal bloom during fall and winter 2008-2009 caused numerous unknown factors in the Strait of Hormuz, Persian Gulf and G...

Lipid recovery and purification from microalgal cells continues to be a significant bottleneck in biodiesel production due to high costs involved and a high energy demand. Therefore, there is a considerable necessity to develop an extraction method which meets the essential requirements of being safe, cost-effective, robust, efficient, selective, environmentally friendly, feasible for large-sca...

Since the interspecific competition represents a critical issue for biodiesel production in open mass cultures of microalgae, laboratory studies aimed to select competitive species receive significant interest. In this work, a laboratory approach based on the method of multisizing cell counting was developed to monitor the competition course of single algal species grown in mixed cultures. Two ...
