“…Fungi appear to be of interest in this context due to their ability to rapidly increase biomass and produce bioactive compounds on almost any type of substrate. Polymers derived from large fruiting-body fungi, mainly belonging to Basidiomycota, have been extensively characterised and described in the literature, especially in the context of medical and pharmaceutical applications [12].…”

The Trichoderma koningiopsis strain showed an extracellular polymers (EPS) synthesis capacity of 1.17 g/L in an optimised Czapek-Dox medium containing sucrose (30 g/L) and yeast extract (7.5 g/L). Three fractions of wall polymers were extracted from the biomass obtained after culture: cold water soluble (WPSZ), hot water soluble (WPSC) and alkali soluble (WPSNaOH), which accounted for 13.3%, 1.8% and 20.2% of the mycelial dry weight, respectively. Structural analyses indicated that the EPS obtained was mannan, and the WPS fractions were glucans containing predominantly →4)-Glc-(1→ linked residues, with branching at →3,6)- as well as →4,6)-positions. FT-IR and FT-Raman analyses showed that α-bonds dominate in the WPSZ and WPSC fractions, whereas β-bonds dominate in the EPS and WPSNaOH fractions. The obtained polymer fractions (PS) showed antioxidant properties in the ABTS, DPPH and FRAP methods and the ability to bind bisphenol A from an aqueous environment. The most important property of the obtained PSs is their ability to reduce germination and inhibit the growth of mycelia of the phytopathogenic Fusarium culmorum strain. The obtained polymers exhibit a number of bioactive properties and can be used in various areas of human life.
