Chemical constituents and antimicrobial activity of wood vinegars at different pyrolysis temperature ranges obtained from Olivers branches.

Pyrolysis is a promising approach for converting biomass to solids, liquids, and gases. Herein wood vinegars (WVs) were produced from pyrolysis of Olivers (EUO) branches in different temperature ranges that were labeled as WV and WV The yield, the physicochemical characteristics, the chemical composition, and the antimicrobial activity of the WVs were comprehensively investigated. During the pyrolysis process, as the temperature increased, the yield of the WVs increased firstly and then decreased, and WV achieved the maximum yield of 236.
