Effects of four organic nitrogen in survival and growth of Neopyropia yezoensis protoplasts Preliminary study

In order to research useful organic nitrogen, survival and growth of Neopyropia yezoensis protoplasts were examined using L-arginine (Arg), L-glutamic acid (Glu), Inosine (Ino) and taurine in 0.1, 1.0 and 10 mM. For survival rates for 1 week in culture, there were no significant differences except Glu in 1.0 and 10 mM. For growth for 3 weeks in culture, Arg in 10 mM was grown over two-times higher compared with control. On the other hand, growth in Glu and taurine were suppressed under every condition. Moreover, growth in Ino in 10 mM was suppressed. Our data suggested that Neopyropia yezoensis use directly organic nitrogen and has a potential to induce growth using organic nitrogen.
