Finally, we kindly request the reviewer to consider that this is the first approach to studying a Chilean hot spring EPS isolation and its functional characterization. We also mention that further work to fully reveal this EPS structure will be necessary using higher resolution NMR spectra combined with chemical techniques. This work has given partial structural elucidation, which can be considered a previous background for other research on this topic.
Fourier transform infrared spectroscopy (FTIR) and NMR spectroscopy data can only be regarded as preliminary.
