主　　题：Spirulina platensis growth germanium dioxide 

摘      要：This study on the effect of different concentrations of germanium dioxide （GeO2） 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 GeO2 could speed up growth and raiseprotein content of S. platensis, and could possibly influence the photosynthesis system. The concentrationrange of GeO2 beneficial to growth of S. platensis is from 5-100 mg/l. GeO2 is proposed to be util-ized to remove contamination by Chlorella spp. usually occurring in the cultivation of Spirulina.
