Yeast is widely used in the baking, biocontrol, brewing, and bio manufacturing industries. In the baking industry alone, around two million tons of yeast are consumed worldwide every year. While yeast brings delicious and healthy lives to humans, we find that stress resistance of yeast is essential for the development of bioindustry. Whether during baking, biocontrol, brewing, bio manufacturing, or in other industries, yeast faces a variety of environmental stresses that have a great impact on its activity, transformation ability, etc., which make the production process uncertain. Therefore, robust yeast strains that can resist various environmental and endogenous stresses are needed. In recent years, many studies have investigated the stress resistance of laboratory strains and specific methods to improve stress resistance; however, applying these findings to industrial yeast is difficult. In this paper, based on summarizing the work of predecessors, we put forward the main steps to improve the stress resistance of industrial yeast systematically, which may provide a reference for researchers.
