Stress or environmental stimuli can cause structural changes
and/or metabolic changes in an organism acting as expression
activator for genes involved in the synthesis of specific compounds that protect the organism [11]. The factors triggering the
expression of this type of genes can be biotic or abiotic. Biotic factors induce changes in the gene expression of the guest, giving
rise to the synthesis of specific compounds that generate resistance to the strange organism. Abiotic factors can be temperature,
osmotic stress, anaerobic conditions, heavy metals, growth regulators, ultraviolet radiation, metabolic repressors, and pHtor, where both heat and cold induce the synthesis or storing of a
group of proteins that increase stress resistance [17,18]. Some successful attempts to adapt yeasts to high temperatures have been
described
