What does this research mean for the field?

Ionic liquid toxicity in biotechnological yeasts is species-dependent and emerges from the interplay between ion-specific properties and their binding affinity to target enzymes like hexokinase. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To evaluate the toxicity profiles of ionic liquid-derived ions across three biotechnologically relevant yeast species and model their interactions with yeast hexokinases.

Overview

In vitro and computational study reveals species-dependent ionic liquid toxicity linked to hexokinase binding in yeasts, indicating enzyme-level mechanisms of chemical tolerance.

Key Points

To evaluate the toxicity profiles of ionic liquid-derived ions across three biotechnologically relevant yeast species and model their interactions with yeast hexokinases.
Assessed toxicity by measuring maximum non-toxic concentration (MNTC) values of selected ionic liquid cations and anions in Saccharomyces cerevisiae, Yarrowia lipolytica, and Kluyveromyces marxianus.
Conducted molecular docking simulations to analyze binding affinities between the evaluated ions and the hexokinase enzymes of each yeast species.
Yarrowia lipolytica exhibited substantially higher tolerance to ionic liquids compared to Kluyveromyces marxianus and Saccharomyces cerevisiae.
Anion toxicity increased consistently from Cl− to [NTf2]− across all three species, with [NTf2]− consistently exhibiting the lowest MNTC values.
Molecular docking revealed that higher binding affinity to hexokinase qualitatively correlated with lower MNTC values, indicating enzyme inhibition contributes to ion toxicity.
