The SaliChem Team met for the final Meeting on 15 December 2016 in Trier, Germany and presented the final results.

Among the participants were the research performers Celabor and PFI, members of the user committee, and a representative from the funding program CORNET. Both research performers presented their respective results on extraction of pharmaceutical active phyto-chemicals and biomass conversion to sugars and ethanol using Spartina maritima, a salt tolerant cordgrass.

Key results:

Spartina maritima accumulates high concentrations of phyto-chemicals with antioxidative and anti-aging activity. Furthermore, Spartina maritima’s composition of structural carbohydrates is comparable to other second generation feedstocks, such as wheat straw and corn stover. The partners could successfully extract the phyto-chemicals using advanced technologies such as super-critical carbon dioxide extraction and additionally convert the remaining solids through successive processes to liquid sugar hydrolyzates that could be fermented to ethanol. A key outcome of the project, is that extraction prior to biomass processing resulted in higher sugar yields than without. The processing intensity can therefore be reduced and costs be saved. An additional benefit, the ethanol productivity from Spartima maritima sugar hydrolyzate was improved in comparison to hydrolyzate from wheat straw or even standard media.

All partners agreed to move the research forward towards industrialization and maximize the exploitation potential of Spartima maritima. Potential funding sources for additional research are being sought.
