Halotolerant enzymes remain active over a broad range of NaCl concentration, without any specific salt dependence. According to salt tolerance, most food fermentations are carried out by non-halophilic microorganisms;however, specific proteins produced by these fermenting bacteria could be adapted to remain active under high salt concentrations.
To date, some research on lipases from halophilic bacteria has been carried out but attention to halotolerant
lipases from non-halophilic microorganisms should be also
done.
