The MacroAlgaeBiorefinery - sustainableproduction of bioenergy carriers and high valueaquatic fish feed from macroalgae- the MAB3 projectAnne-Belinda Bjerre, Teknologisk Institut, DenmarkLars Nikolaisen, Teknologisk Institut, Denmark16th November 2012.Workshop in Nordic Algae Network and Blue Bio, Ås, Norway

    3. 3. The MacroAlgaeBiorefinery : MAB3Title: Sustainable production of 3G energy carriers (ethanol,butanol og biogas) and fish feed from macroalgae (Laminariadigitata and Saccharina latissima)Project period: 1st of March 2012 - 1st of March 2016Financied by the Danish Strategic Research Council (20,4mill. DKK total budget på 24 mill. DKK)12 Partnere from Denmark, Irland, Italy, GermanyEducation of 4 ph.d. and 2 post docsCoordinator: Danish Technological Institute v/ Anne-Belinda Bjerre

    5. 5. BiorefineryDefinition: Integrated and combined processes for the conversion of biomass into a variety of food, feed, chemicals, biomaterials, and energy – at the same time maximising the value of the biomass and minimising the waste
    6. 6. Transportation fuel from algae Macroalgae: High contents of carbohydrates (45-65%) Microalgae: High contents of lipids (25- 35%)

    8. 8. In MAB3, fish feed (protein) will be the value added product, In MAB3, fish feed (protein) will be the value added product,derived from production of energy carriers e.g. ethanol or derived from production of energy carriers e.g. ethanol orbiogas biogas
    9. 9. Introduction to MAB3 Hypothesis: 1) Two brown macroalgae can be upgraded to energy carriers (either bioethanol, buthanol or biogas or combinations hereof) by conversion of 80% of the fermentable sugars, leaving behind a concentrated solid fraction rich in protein and (for liquid biofuels also) lipids, which can be used for fish feed. 2) A substantial amount (90%) of the remaining, undigested sugars i.e. the C5 sugars can be converted to additional value-added amino acids (isoleucine and arginine) for fish feed supplement. The project Best practical methods, processes and technologies will be tested Best practical methods, processes and technologies will be tested and optimised to meet these goals and optimised to meet these goals

    11. 11. How brown algae are composed Brown Algae lack real, distinct, secondary cell walls (no lignin). The cell walls in brown algae thalli are made up mainly of cellulose “micro- fibrils” or fibrils forming a felty network. The fibrils are rarely ordered in parallel manner as in higher plants or even some green algal species. In brown algae, these felty fibre networks are layered and embedded in a polysaccharide matrix. Gentle pretreatment technologies will be needed for disrupting the biomass before enzyme hydrolysis

    15. 15. Conclusions:Brown algae are fine substrates for ethanol production due to high contents ofpolysaccharides. Challenges are: – Identification of most suitable enzyme mixtures for fully hydrolysis to monomeric sugarsWashing and auger pressing were efficient pretreatment methods for waterand salt removal in green algae, new test on brown algae have beenperformed. – Room for improvement e.g. by enzyme treatment.Brown algae lack real, distinct, secondary cell walls (no lignin). – Pretreatment conditions (prior to enzymatic hydrolysis) are less severe than for lignocellulosic biomass materials:Ball milling was the most effective pretretment of Chatamorpha linum prior toSSF with Baker’s yeast fermentation in combination with Celluclast andNovozym 188. – Improved yields are expected using more targeting enzymes and other microorganisms during fermentation.
