Biomasa de spirulină îmbogăţită cu iod–Sursă alternativă de iod
Studia Universitatis Moldaviae: Stiinte reale si ale naturii, 2007 The productivity of cyanobacteria Spirulina platensis and iodine accumulation in biomass at it cultivation in the pre-sence of KI with/without CoNO32 have been determined. The supplementation in the first day is more favorable for obtaining of iodine enriched biomass. Iodine content is higher in biomass cultivated in the presence of ratio KI: CoNO32 as
