Ulva rigida seaweed is constituted by ulvan, which a sulfated polysaccharide with uses in wide variety of applications. After the ulvan-oriented extraction process, crystalline and recalcitrant residue, so-called pulp, appears. In this work, residue was valorized through multiple-stage process. The total processing algae consists hot water extraction, acid hydrolysis, ABE fermentation, distilla...

Microalgae have been widely reported as a promising source of biofuels, mainly based on their high areal productivity of biomass and lipids as triacylglycerides and the possibility for cultivation on non-arable land. The isolation and selection of suitable strains that are robust and display high growth and lipid accumulation rates is an important prerequisite for their successful cultivation a...

The current scenario in renewable energy is focused on development of alternate and sustainable energy sources, amongst which microalgae stands as one of the promising feedstock for biofuel production. It is well known that microalgae generate much larger amounts of biofuels in a shorter time than other sources based on plant seeds. However, the greatest challenge in a transition to algae-based...

Microalgae are widely viewed as a promising and sustainable source of renewable chemicals and biofuels. Botryococcus braunii synthesizes and secretes significant amounts of long-chain (C30 -C40 ) hydrocarbons that can be subsequently converted into gasoline, diesel, and aviation fuel. B. braunii cultures are not axenic and the effects of co-cultured microorganisms on B. braunii growth and hydro...

Intensive cultivation of freshwater macroalgae is likely to increase with the development of an algal biofuels industry and algal bioremediation. However, target freshwater macroalgae species suitable for large-scale intensive cultivation have not yet been identified. Therefore, as a first step to identifying target species, we compared the productivity, growth and biochemical composition of th...

Microalgae, a group of microorganisms that grow using sunlight as the sole energy source and carbon dioxide as an only carbon source, have been considered as a feedstock of choice for the production of biofuels such as biodiesel. To explore the economic feasibility of such application, however, many technical hurdles must first be overcome; the selection and/or screening of competent species ar...

Due to the depletion of the fossil fuels and major concerns about the security of energy in the future to produce fuels, the importance of utilizing the renewable energies is distinguished. Nowadays there has been a growing interest for biofuels. Thus, this paper reveals a general optimization model which enables the selection of preprocessing centers for the biomass, biofuel plants, and wareho...

There were considered the technological and biological aspects of perspective microalgae as a resource alternative energy. An overview analysis current state art from point view assessing use renewable raw material high productivity for producing third-generation biofuels is presented. In recent decades, research in field technologies production biomass energy purposes has focused mainly on sea...

The continued burning of fossil fuels since the beginning last century led to higher emissions greenhouse gases and thus leads global warming. Microalgae are one most important sources green hydrocarbons because this type algae has a high percentage lipids rapid growth, consumes carbon dioxide in large quantities. Besides, cultivation these types does not require arable land. This review aims e...

The development of clean and renewable biofuels has been wide concern on the topic energy environmental issues. As a kind biomass with great application prospects, microalgae have many advantages are used in fields protection as well food or feed production for humans animals. However, high cost harvesting is main bottleneck industrial large scale. Self-flocculation cost-efficient promising met...
