摘要

Abstract

Fe2+ acted as an accessorial factor for many cellular enzymatic reactions is very important for seaweed growth and development

but the Fe2+ requirement in nori had not been seen

Porphyra yezoensis cells were separated enzymatically and cultured in a series of sterilized seawater media containing various concentrations of Fe2+. The growth development and cell were investigated in this work. Through this experiment

two biologically-meant concentration scales were found

one is low concentrations

12.1–102.1 μg/L

10–100 times than that in seawater

favoring the development of isolated cells ofPorphyra and the other was high concentrations

more than 10mg/L inhibiting the cell growth

leading to the deformity and shrinkage of the cells. At the concentration of 50 mg/L

the cells stopped growing and died eventually.
