| 摘 要： | This study on the effect of different concentrations of germanium dioxide (GeO_2) on the specificgrowth rate (SGR), pigment contents, protein content and amino acid composition of Spirulina platensisshowed that Ge was not the essential element of this alga; that GeO_2 could speed up growth and raiseprotein content of S. platensis, and could possibly influence the photosynthesis system. The concentrationrange of GeO_2 beneficial to growth of S. platensis is from 5-100 mg/l. GeO_2 is proposed to be util-ized to remove contamination by Chlorella spp. usually occurring in the cultivation of Spirulina.
