Fungi open new possibilities for anaerobic fermentation of organic residues

摘要: Large amounts of fibre-rich organic waste material from public green and private gardens have to be treated environmentally friendly; however, this biomass has low biogas yields. This study investigated the presence fungi in full-scale plants as well laboratory reactors elucidated importance for process. The dominating members eukaryotic community were identified by analyzing 18S rRNA gene internal transcribed spacer 1 (ITS1) region fragments clone libraries. These identifications accompanied diverse microscopic techniques such fluorescence microscopy conventional scanning electron microscopy. Cells presumably fungal origin characterized intensive about order magnitude larger than prokaryotic cells. Molecular enabled identify subphyla Agaricomycotina, Mucoromycotina, Pezizomycotina, Pucciniomycotina Saccharomycotina class Neocallimastigomycetes. Members these groups can important microbial degradation complex compounds, due ability penetrate cell walls, thus open cells influx bacteria, further enhancing degradation. Optimal treatment biowaste depends on amount lignocelluloses. Targeted application process will wider possibilities anaerobic result better utilization a renewable energy resource. Due higher temperature optima cellulolytic enzymes, thermophilic is suggested biomass.
