Properties and anti-fungal activity of liquid by-products from softwood bark carbonization.

ABSTRACT: This study investigated the potential use of pyrolysis liquid from bark as an anti-fungal substance against food decaying fungi. Four different fractions of pyrolysis liquid were collected during variable temperature phases of the pyrolysis process: F1 (25-260 °C), F2 (260-512 °C), F3 (512-800 °C), and F4 (800-25 °C). The thermal degradation of bark material was assessed using TGA analysis. The concentration, pH, total phenolic content, and functional groups of the liquid samples were determined. Additionally, the molecular composition was examined using UHPLC and QToF mass spectrometry methods. Fungal species were isolated from bell pepper and animal fat and identified through microscopic observation and DNA sequencing. The anti-fungal activity of the liquid fractions was evaluated using
