Extreme environment microorganisms against heat stress

Throughout its life cycle, the plant faces adversity from biotic stresses, such as the presence of herbivores and parasites, as well as abiotic stresses, such as high temperatures, which are increasingly afflicting plants through climate change. 

Heat stress is a serious factor in reducing crop yields by blocking various processes, such as: 

- Water uptake and translocation capacity, 

- Nutrient absorption, 

- Biosynthesis of primary and secondary metabolites, 

- Photosynthesis. 

In the fight against the effects of heat stress stand microorganisms from extreme environments, called thermophiles. 

Thermophilic microorganisms, such as Bacillus, can withstand temperatures exceeding even 50°C and improve the strength and quality of crops and soils through:

- Nitrogen fixation, 

- Potassium and phosphate solubilization, 

- Heavy metal resistance, 

- Growth-inducing hormones production, 

- Reduction of pathogens. 

The addition of thermophiles in the form of bio-fertilizers, bio-inoculants and other preparations increases the percentage of germinated seeds, improves plant growth and lengthens, and deepens their root system while keeping soil components in balance.

Research confirms that extremophiles are a low-cost and environmentally safe alternative to artificial fertilizers, in addition, they show amazing abilities in combating environmental stresses such as high temperatures.
