Table 4 Melting temperature (T m) of H0HC94 in 0.9 M IL’s, DMF, and NaCl, both in the absence and presence of 100 mM glucose (Glc)

From: Using the β-glucosidase catalyzed reaction product glucose to improve the ionic liquid tolerance of β-glucosidases

  1. ∆Tm was calculated by subtracting the zero IL H0HC94 Tm (53.73 °C) from the Tm of H0HC94 in 0.9 M IL and also from the Tm of H0HC94 0.9 M IL and Glc co-solvent. Data are expressed in °C and represent mean ± SD of three independent experiments, each performed in triplicate
