Abstract

Selection of microorganisms for the mobilization of cellulolytic agricultural biomass for energy production. R. Di Bonito, D. Taschini, C. Viola, Campi otti C.A. Unit Energy Efficiency in Agriculure, ENEA Casaccia, Roma, Italy The production of biofuels as renewable energy source could significantly reduce the negati ve impact of fossil fuels. However, this activity has resulted in increasing land cultivation specifically with carbohydrate-rich crops for energy production, and resulting shortage of crop production for food . The use of residual agricultural biomass as a substrate for biofuels or biogas production could improve the sustainabi lity of the bio-energy production but sti li requires the improvement of the technologies for the mobilization of the sugarpolymers cellulose and hemice lluloses that are the main components of the pian! biomass. Several microorganisms are able to produce the cellulose-degrading systems (endoglucanases, exoglucanases and glucosidases) and purified enzymes are available. A great diversity is still present in the environment for such traits and needs to be explored. The aim ofth is work is to illustrate th e selection and the characterization of novel bacterial isolates which are able to de-polymerize cellulose. We have perfonned an enrichment culture from rotten palm tissue and isolated mesophilic stra ins able to grow on carboxy-methylcellulose and cellobiose as so le carbon so urces under aerobic conditions. The phylogenetic affiliation was obtained by sequenci ng of the 16S rRNA gene and has allowed the identification of Serratia sp., Providencia sp., Enterobacter sp., Lysinibacillus sp., Pseudomonas sp., Raoultella sp.
