Development results
1. Two species of marine harmful microalgae Alexandrium tamarense and Cochlodinium polykrikoides were separated and cultured, and at least five other marine microalgae were isolated an cultured. In addition, 19 strains of harmful freshwater microalgae were isolated and information on physiological characteristics was obtained.
2. More than 10 species of harmful microalgal algae microorganisms in seawater have been separated, and the algae efficiency and physiological characteristics have been obtaind. In addition, 4 patent strains of algae microorganisms have been deposited and 4 patents have been registered and 1 applied. Freshwater harmful microalgal symbiosis also isolated 19 species and 32 strains.
3. A network analysis was performed based on the environmental factors, bacterial community analysis results, and green algae occurrence results in the downstream of the Nakdong River, and through this, 55 species of microorganisms estimated tointeract with green algae were extracted and analyzed.
4. Five kinds of bacteriophage were isolated, three kinds of hemolytic bacteriophage from symbiotic microorganisms were isolated, and the genome of one kind of bacteriophagewas analyzed. In addition, three kinds of bacteriophage were deposited.
5. As a result of comparative analysis of seawater/freshwater microbial community structure, there was a marked difference in the microbial lifestyle (free-living and particle-associated fraction) community structure, and mainly influenced by abiotic environmental factors (water temperature, salinity and nutrients, pH, DO). As a result of network analysis, free-living microorganisms interacted most actively, and the role of herb microorganisms was identified.
6. The distribution of harmful microalgae symbiotic microorganisms was analyzed in-depth to analyze the qualitative and quantitative analysis of the bacterial distribution, and the correlations through the systematic diagram.
7. Mesocosm In field experiments, a variety of algicidal microorganisms, algicidal substances, natural substances, as well as a Cochlodinium trap with added chemotaxis function was installed to verify the effect of reducing less than 60% of the standard for red tide outbreak warning.
