Various stress resistant genes or mechanisms presented in microorganisms, and the discovery of these mechanisms laid a sound foundation for the directional enhancement of microbial stress tolerance. The main techniques of enhancing stress resistance of microorganisms contain over expression of stress-resistant genes, long-term adaptive evolution, genome shuffling, and heterologous expression of stress-resistant genes. These biological techniques can efficiently improve the stress resistance of industrial and environmental microorganisms, which surely benefited the bacteria based on industrial production and degradation of environmental pollutants.
