    Using genetic engineering technology, Professor Jonathan greiser of weizman Institute in Israel has developed a genetically modified alga with stronger environmental adaptability, which can be used to produce biofuels and fish feed Algae is a kind of aquatic plant with wide distribution, rapid growth and high energy value Like other plants, algae also face the threat of pests and environmental pollution, especially the invasion of alien species If one kind of algae is cultivated in the pond without protection, it is likely that another kind of algae will grow in the pond soon In addition, algae are also vulnerable to bacteria and viruses, once infected, they will soon die In view of this situation, Professor greiser modified the molecular mechanism by using genetic engineering technology, and developed a kind of algal variety that can resist the invasion of foreign algae and bacteria In order to prevent the leakage of genetically modified algae from polluting the natural algae, the researchers also made the algae have the ability of self destruction through genetic coding Once it leaks into rivers, lakes and seas, as long as the self destruction gene is activated, it will die within six hours Professor greiser said that with the aggravation of global warming, the energy value of algae is increasingly recognized However, due to the sensitivity of algae to environment and diseases, it brings potential risks to large-scale aquaculture The transgenic algae developed by them not only has stronger adaptability, but also is suitable for fresh water and sea water, and can also develop the required varieties according to the requirements of customers, with good application prospects At present, the company has signed a cooperation agreement with a biofuel company in the United States and a fish feed manufacturer in Israel, which will soon be put on the market.
