Method for growing brown algae and method for producing hydrated solid with brown algae

摘要

PROBLEM TO BE SOLVED: To provide growth methods of brown algae that can efficiently grow brown algae while inhibiting microalgae and the like from growth and proliferation.SOLUTION: The present invention provides a growth method of brown algae, characterized by growing brown algae by putting either one or more of spores, immatures, and adults of brown algae into an adjusted sea water which is adjusted so that an iron concentration becomes 5 μg/L or more, and irradiating with light having a wavelength of 400-500 nm and a light intensity of 10 μmol/m/s or more to less than 40 μmol/m/s.SELECTED DRAWING: Figure 4
