Third-generation biohydrogen production from algae biomass and its hydrolysis derivatives

Abstract

The development of technologies to obtain renewable and cleaner energy is a global issue. Hydrogen is a clean fuel-its burning generates water only. A biological process, such as fermentation of carbohydrates from renewable raw materials, produces biohydrogen. Recently, researchers have turned their attention to the use of algal biomasses bearing high concentration of polysaccharides as raw materials for the so-called third-generation biohydrogen production. Algae have the ability to sequester large amounts of CO2 and to grow at high rates as compared with other types of biomass. In addition, algae are aquatic organisms, so they do not compete with food production. Furthermore, these organisms do not contain lignin, which facilitates their hydrolysis. In this project, the macroalga Kappaphycus alvarezii will constitute the source of biomass. This species consists of about 50-70% of carbohydrates, especially carrageenan and cellulose. The first stage of this project will deal with the isolation of H2-producing microorganisms from an anaerobic sludge and their identification by molecular techniques. The isolate should be able to produce H2 from glucose and galactose, the main monosaccharides derived from the hydrolysis of algae. Thereafter, the effect of fermentation inhibitors derived from alga hydrolysis; e.g., 5-hydroxymethylfurfural (HMF), levulinic acid, and formic acid, on H2 production by the isolated microorganism will be investigated. In a second stage, the alga biomass as whole and/or as the hydrolysate will be employed during fermentative H2 production. The hydrolysate will be obtained by using the optimum conditions established for alga hydrolysis with hydrochloric acid by means of experimental design; acid concentration, time, and temperature will be the tested variables. To sum up, this project will investigate the potential of K. alvarezzi biomass to act as substrate for third-generation biohydrogen production; it will also evaluate the effect of monosaccharides and inhibitors derived from algal biomass hydrolysis on fermentative H2 production.
