| Abstract: | Prorocentrum micans was cultivated in different media including f/2, f/4/ f/8, f/20, f/25, f/50, f/100 and f/200. Results showed that media influence
the growth of P. micans. The biomass of P. micans in rich nutrition medium was much higher than in poor nutrition medium. Nitric oxide can promote or inhibit the growth of
P. micans in all, media. Nitric oxide at the concentration of 1.4×10−6 mol L−1 promoted the growth of P. micans significantly when added only once during the cultivation. When added twice a day, nitric oxide at the concentration of 1.4×10−9 mol L−1 promoted the growth of P. micans significantly, while nitric oxide at the concentrations of 1.4×10−5 mol L−1 and 1.4×10−6 mol L−1 inhibited the growth. Therefore, nitric oxide, media and the ways to add nitric oxide influenced the growth of P. micans respectively. |
