Microalgae feedstock production can be integrated with wastewater and industrial sources of carbon dioxide. This study reviews the literature on algae grown on wastewater and includes a preliminary analysis of algal production based on anaerobic digestion sludge centrate from the Howard F. Curren Advanced Wastewater Treatment Plant (HFC AWTP) in Tampa, Florida and secondary effluent from the Ci...

This article reviews the current state-of-theart for algae use in aquaculture, plus recent developments in algal biomass as a microor bulk ingredient in formulated animal feeds (terrestrial livestock and aquaculture species). Microalgae provide an important direct or indirect feed source for early developmental stages of many farmed finfish, shellfish and invertebrate species. Hatcheries typica...

Microalgae are promising sources of sustainable biofuels, however high harvesting and enriching costs hamper economic competitiveness. Foam flotation––a low-cost, low-energy adsorptive bubble separation technique––may bridge this gap, yet its efficiency adoption is compromised by a perceived trade-off (based on batch operation) between two key performance indicators: recovery percentage (R%) co...

Biofuels are considered to be the best way to reduce green house gas emission and alternative to pollutant fossil fuels. At present research is being conducted by culturing algae to produce different fuels like biodiesel, bioethanol etc. Using algae to produce biodiesel would be the only viable method to replace the need of gasoline used for automotive today. Experiments were planned to produce...

BACKGROUND Biofuel has been the focus of intensive global research over the past few years. The development of 4th generation biofuel production (algae-to-biofuels) based on metabolic engineering of algae is still in its infancy, one of the main barriers is our lacking of understanding of microalgal growth, metabolism and biofuel production. Although fatty acid (FA) biosynthesis pathway genes h...

To mitigate some of the potentially deleterious environmental and agricultural consequences associated with current land-based-biofuel feedstocks, we propose the use of biofuels derived from aquatic microbial oxygenic photoautotrophs (AMOPs), more commonly known as cyanobacteria, algae, and diatoms. Herein we review their demonstrated productivity in mass culturing and aspects of their physiolo...

Introduction Biodiesel producers have long recognized the need for new sources of oil feedstock if biodiesel is to continue displacing petroleum-based diesel fuel. One potential source of oil that could minimize competition with food crops is microbial oil, with photosynthetic algae being the most widely studied option. An understanding of algal lipids, their native biochemistry and interaction...

Biofuel and biochemical production by photosynthetic microorganisms such as cyanobacteria and algae is attractive to improve energy security and to reduce CO2 emission, contributing to the environmental problems such as global warming. Although biofuel production by photosynthetic microorganisms is called as the third generation biofuels, and significant innovation is necessary for the feasibil...

Renewable Algal Energy, LLC (Kingsport, Tenn.) Algal Biodiesel via Innovative Harvesting and Aquaculture Systems Renewable Algal Energy LLC, will leverage its experience in algal aquaculture, harvesting, and extraction, to demonstrate at small commercial-scale, improved, low cost, energy-efficient methods for harvesting and dewatering algae that contribute to an algal oil product that is cost-c...

The world seems to be raising its energy needs owing to an expanding population and people’s desire for higher living standards. Diversification biofuel sources have become an important energy issue in recent times. Among the various resources, algal biomass has received much attention in the recent years due to its relatively high growth rate, its vast potential to reduce greenhouse gas (GHG) ...
