“…is may be due to the inhibition of the pathway to protein synthesis in favor of providing amino groups to generate phosphocarbamates, which are further used to synthesize arginine. Arginine is a precursor for the synthesis of PSP toxin, so that when phosphorus is limited, the synthesis of cytotoxin is accelerated [20].…”

In the era of information explosion, mobile data is developing rapidly, and many fields are facing the challenges of data collection, analysis and operation. Heterosigma akashiwo is a kind of wide temperature and wide salt algae, belonging to the class Echinococcus and the genus heterobenthos. It is widely distributed in the coastal waters of the world. It has formed harmful red tides for many times in many countries, causing a large number of fish deaths, causing great economic losses and serious damage to aquatic resources. If toxic red tides break out frequently, they will pose a great threat to public health. Seawater eutrophication is the main environmental inducement for the formation of red tide by Heterosigma akashiwo. In particular, the content of nutrients in seawater significantly affects the reproduction of Heterosigma akashiwo and the excessive proliferation of plankton such as algae. At the same time, a large number of planktons will devour the dissolved oxygen in the water, thus affecting the photosynthesis of the water body, resulting in the deterioration of the water quality and the damage to the functions of ecology and water resources. As for the effects of nitrogen, phosphorus, iron and different vitamins on the growth of Heterosigma akashiwo, this paper takes Heterosigma akashiwo as the research object, and focuses on the analysis of the effects of ammonium chloride, urea and sodium dihydrogen phosphate on the proliferation of Heterosigma akashiwo. e results showed that the higher or lower the concentration of nitrogen and phosphorus, the slower the proliferation rate of Heterosigma akashiwo; Heterosigma akashiwo had the maximum proliferation rate under the nitrogen concentration of 300-500 μmol/L; At the concentration of 10∼15 μmol/L phosphorus, its growth rate is the fastest and its proliferation level is the highest. e selected nitrogen and phosphorus have a very significant impact on the proliferation of microalgae.
