Is pyrolysis bio-oil prone to microbial conversion into added-value products?

In view of the potential application pyrolysis-based biotechnologies, it is crucial to look for novel microorganisms able convert pyrolysis-derived products, in particular bio-oil water-soluble constituent, into valuable compounds. For first time, this paper proposed a survey on collection bacterial, yeast, and fungal strains with well-known industrial properties as well new bacterial isolates order select microbes both tolerate inhibitors products. This found that aqueous phase (BOAP) obtained from intermediate pyrolysis could be metabolized by whereas several dilutions are needed do not hamper cell viability many tested yeast isolates. To process BOAP Saccharomyces cerevisiae L13, selected most industrially relevant strain, was adopted fraction hydrolysate ethanol without any detoxification step. The fermenting performances were much greater than those benchmark strain S. L13 proved strong candidate bioethanol production hydrolysates. study demonstrated search promising approach future development oil-based biorefinery platforms.
