Saccharification of Marine Microalgae Using Marine Bacteria for Ethanol Production

Biochemical characterization of microalgal biomass from freshwater species isolated in Alberta, Canada for animal feed applications

“…While all microalgae produce hydrocarbons as energy and carbon stores, some groups of microalgae have a preference for starch rather than lipid accumulation and these species are gaining attention as potential feedstocks for bioethanol production [59]. The fact that C. vulgaris biomass used in this study contained CHO composed of a roughly equal mixture of both starch (52% of total CHO) and fiber (48% of total CHO) is in agreement with Matsumoto et al [60]. These authors reported that Chlorella sp.…”

“…It is important to also note that, of the fiber fraction, generally comprised of cellulose, hemicellulose and lignin in most terrestrial plants, microalgae fiber contains no lignin and low hemicellulose levels. As a result, it has been proposed that the use of starch-rich algal biomass as feedstock for bioethanol production may be advantageous over conventional feedstocks by providing increased hydrolysis efficiency, higher fermentable yields and reduced production costs [60]. M. reisseri, being so similar in other aspects of its growth performance and biochemical composition, it is not surprising to see similar CHO compositions of starch (64% of total CHO) and fiber (36% of total CHO).…”

Ulvan: A Versatile Platform of Biomaterials from Renewable Resources

“…Besides biodiesel, algae can be cultivated and can be used as a feedstock for the production of bioethanol (John et al, 2011). In particular macroalgae (seaweed) can produce huge amount of carbohydrates per year www.intechopen.com (Matsumoto et al, 2003) that suitably processed through specific fermentation processes would provide renewable and sustainable biofuel. Algae represent also an advantageous resource of chemicals and building block materials that can be tailored through proper biorefinering processes according to the different envisaged applications.…”

“…alginate). Polysaccharides of algal origins are gaining particular attention due to their abundance, renewability (Matsumoto et al, 2003) and to their peculiar chemical composition not found in any other organisms. Over the last few years medical and pharmaceutical industries have shown an increasing interest in alginate (d'Ayala et al, 2008), an anionic polysaccharide widely distributed in the cell walls of brown algae.…”

Bioethanol Production Using Starch Extracted from Microalga Stigeoclonium sp., Kutz. BUM11007 Cultivated in Domestic Wastewater

“…For the past years several alternative feedstocks; sucrose based, starch based and lignocellulosics have been tested for bio-ethanol production. Microalgae are phototrophic organisms that have ability to grow rapidly by fixing atmospheric carbon dioxide and accumulate carbohydrates mainly in the form of starch, Moreover micro-algae do not warrant arable land for their growth thereby do not compete food crops, thereby micro-algae provide greater advantages sustainably (Matsumoto et al, 2003). Holding all the desirable characteristics, micro-algae are considered interesting and eligible feedstock for bio-ethanol (Gao et al, 2010).…”
