Abstract

This study aims were to know the effect of ferric chloride (FeCl3) on biomass concentration andprotein content of microalgae Chaetoceros calcitrans and determine the best concentration of ferricchloride for production of microalgae Chaetoceros calcitrans with highest protein content. This studywas designed with randomized block design with single factor. The factor was different ferric chlorideconcentration consist of 4 concentration, i.e. 0 µM, 12 µM, 24 µM and 36 µM. Each treatment wasgrouped into 4 based on time of cultivation. The data obtained were analyzed by analyzed of variancefollowed by least significant difference test, if a treatment had significant effect. The result showed thataddition of ferric chloride had very significant effect on the b iomass concentration and protein content.The highest biomass concentration and protein content was obtained from the microalgae Chaetoceroscalcitrans which was cultivated in 36 µM ferric chloride amounted of 4.1 x 107cell/mL and 25.41%. Keywords: biomass, Chaetoceros calcitrans, Ferric Chloride, NPSi, protein.
