Novel anti-microbial properties for wood vinegar derived from Canadian softwood biomass pyrolysis

Pyrovac Inc.是一家位于魁北克的加拿大公司，专门从事生物质的热解。作为一家技术提供商和工业设备制造商，该公司渴望为其热解工艺所实现的生物质衍生热解产品找到新市场，因此他们与INRS接洽。生物质的典型热解产生称为生物炭的固相和称为木醋液（WV）的液相。WV具有丰富的生物化学成分，可以开发。在魁北克，软木是一种主要的树种，Pyrovac希望扩大其WV天然产品在其他应用领域的使用，如食品应用、生物化妆品或抗菌剂市场。事实上，抗菌剂的应用代表了一个具有商业潜力的未开发领域，Pyrovac Inc.希望通过INRS-ETE探索此应用。本项目的主要目标是测试软木木醋液的抗微生物作用。该项目包括三个子目标：a）木醋液对不同微生物的影响; B）确定木醋液的最佳抑菌浓度;以及c）评价最佳木醋液剂量的抑菌效果。

Pyrovac Inc. is a Canadian company based in Quebec which is specialized in the pyrolysis of biomass. As atechnology provider and industrial equipment manufacturer, the company is eager to find new markets for thebiomass-derived pyrolysis products enabled by its pyrolysis process and hence they approached INRS. Typicalpyrolysis of biomass produces a solid phase called biochar and a liquid phase referred to as wood vinegar(WV). WV has a rich biochemical composition which can be exploited. In Quebec, resinous wood is apredominant species and Pyrovac would like to expand usage of its WV natural product in other applicationdomains, such as food applications, biocosmetics or the antimicrobial market. Indeed, antimicrobialapplications represent an unexplored area which has commercial potential and Pyrovac Inc. wishes to explorethis application with INRS-ETE. The main goal of the proposed engage project is the testing of anti-microbialaction of softwood-derived wood vinegar. The project comprises three sub-objectives: a) effect of woodvinegar on different microorganisms; b) determination of the optimum concentration of the wood vinegar foran anti-microbial action; and c) evaluation of anti-microbial effectiveness of the optimized wood vinegardosage.
