Resumen

MEJIA-BARAJAS, Jorge A; MONTOYA-PEREZ, Rocío; CORTES-ROJO, Christian  y  SAAVEDRA-MOLINA, Alfredo. Thermotolerant Yeast: Industrial Applications, Oxidative Stress and Antioxidant Response. Inf. tecnol. [online]. 2016, vol.27, n.4, pp.03-16. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642016000400002.

A review on characteristics and applications of thermo tolerant yeast, focused on industrial applications and physiological changes that experienced by yeasts, with particular emphasis on oxidative stress and antioxidant response, is presented. Yeasts are widely applied in biotechnology and are the microorganisms most used in medical research and industrial processes. One of the traditional uses of yeast is fermentation, by which beverage, foods and proteins, among others products, can be obtained. However, in this process like in others that use yeasts, high temperatures are generated, causing physiological changes, affecting their growth and viability. This has generated an interest in studying and formulating yeasts capable of growing at elevated temperatures (thermo tolerant yeast). Therefore, it is important to characterize yeast strains to be used in fermentation processes at high temperatures.

Palabras clave : thermo tolerant yeast; applications; oxidative stress; antioxidant response; biotechnology.
