The study on the effect of NO on the growth ofChaetoceros curvisetus

This article studied nitric oxide (NO) effect on the growth ofChaetoceros, curvisetus in chemistry for the first time. Nitric oxide was added into the media with 4 different nutrient concentrations f/2, f/50, f/100, and f/200 when the alga was growing. The growth ofC. curvisetus could be obviously promoted or inhibited during the cultivation process in No enriched media of different concentrations. The growth curve in such media showed a sharp single peak that is the optimal NO concentration for the alga growth, which is consistent with the influence of NO on the growth of high plants. In addition,C. curvisetus can produce NO by itself during, the growth. Therefore, using NO could effectively regulate the algae growth, which is important in real tide control and remediation.
