Overview
Thanks to the inspiration after communicating with Angel Yeast and Fufeng Biology. The details we left out in food safety when designing the project, was provided by them.
Our original goal is to help food industry. They remind us of food safety issues.People's acceptance of genetically modified food is relatively low, and it is not recommended for application in the food industry.
So we decide to explore the application in other fields
Who are the proposed end users?
Salinity-resistant bacteria have broad application prospects in the field of biotechnology, we can find key functional molecules in response to saline-alkali environment by analyzing the common anti-stress mechanism of bacteria, improve the salinity resistance of engineering bacteria through genetic engineering means using anti-stress components, and develop and use these salinity-resistant bacteria to adapt to the environmental department to repair the polluted environment, industrial enterprises, agricultural departments, fermentation industry production in the production of high salinity environment.
According to our investigation, environmental governance departments can use salinity-resistant bacteria to deal with heavy metal pollution through bioremediation and other methods. Industrial enterprises can use salinity-resistant bacteria to produce enzymes to develop various products. The agricultural sector and farmers can use salinity-tolerant bacteria to improve crop salinity tolerance through rhizosphere bacteria, for example. In the fermentation industry, salinity-resistant bacteria can be used as chassis cells to establish an open fermentation system.
In short, whether it is environmental governance or economic development, by continuously excavating and applying these common stress resistance mechanisms of bacteria, we can obtain a wide range of salinity-resistant microbial resources. They will seek the well-being of all walks of life and the population at large in a unique way. With the continuous progress of biotechnology, it is believed that its application prospects in more fields will still be broad and infinite.
How to use our project？
Using these possible universal salinity tolerance genes, we can genetically engineer various microorganisms, such as E. coli, lactic acid bacteria, pyruvate bacteria, etc., to adapt the target strain to high salt conditions in different environments, thereby improving production efficiency and product quality. This will greatly promote the development of microbial engineering.
What we can do for the world？
In industrial production
（1）Enzymes produced by bacteria that are tolerant to salinity have several industrial benefits, including being inexpensive, stable, and having high substrate solubility, resulting in increased yield. Industrial enzymes are projected to reach £8.7 billion by 2026, growing at an annual rate of 6.3%. Hydrolases make up 75% of the enzymes produced by salt-tolerant bacteria. The most extensively researched enzymes are proteases, amylases, cellulases, and lipases. Therefore, across the globe, an increasing number of researchers are promoting the screening of viable functional strains from a multitude of harsh environments and utilising them to generate enzymes with tolerant characteristics.
(2) Salt-stressed cells may synthesise greater quantities of compatible solutes, specifically proline, glycine, citrulline and N-acetyl tyrosine, alongside lower volumes of branched-chain amino acids, with potential industrial applications as protective agents, anti-desiccants, and heat distortion preventatives in the healthcare, cosmetics, and food sectors.
In agricultural development
(1) Inoculation of bacteria with high salt tolerance can improve plant salt tolerance. For instance, the inter-root bacteria of alfalfa, known as Salt-tolerant Phosphorus Solubilising Bacteria (SPSB), have been found to reduce the detrimental effects of salt on alfalfa and facilitate its growth in saline soil.
(2) Salt-tolerant bacteria can be converted into bio-fertiliser. For instance, the salt-tolerant bacterium TY0307, which was isolated from high-yielding paddy soil, has the potential to enhance rice growth and may be utilised for the development of biofertilisers.
