Outline of Final Research Achievements

Muconates are the key intermediates in biodegradation of natural or unnatural aromatic compounds (e.e. lignin, plastics and dyes), which means that the exploration of novel fermentation process of muconates can give a new insight for utilization of waste aromatic compounds, such as ethanol production. The present study focused on the anaerobic mineralization of muconates as a sole carbon source. The anaerobical enrichment culture of soil samples by using cis,cis-muconic acid as a sole carbon source gave 4 microbial strains which can mineralize this compounds in anaerobic condition. The precursor compound of 2-hydroxymuconic semialdehyde, the other type of muconate, could be successfully synthesized.
