Characteristics of protic ionic liquids based on triethanolammonium salts of biologically active carboxylic acids and their impact on the growth properties of the Rhizopus oryzae fungus

Resumo

A series of protic alkanolammonium ionic liquids (ILs) based on triethanolammonium salts (protatranes) of biologically active carboxylic acids (cinnamic, benzoic, oxalic, malonic, succinic, salicylic, and citric acids) is synthesized and characterized. Their biological activity against the Rhizopus oryzae F-814 fungus is studied. The presence of ionic liquids in a culture medium gives rise to the biomass of the fungus growing by 8 to 24%, depending on the salt concentration and its composition.
