Özet
This study investigated the effects of ammonium nitrate (AN) and agricultural N:P:K (10:10:40) fertilizer (AF) on the growth and pigment composition of Arthrospira platensis Geitler. In the first experiment, the maximum cellular concentration was observed in group AN2, and differed significantly from the control group (p<0.05). The ammonium nitrate concentrations of groups AN1-3 promoted growth. The concentrations of ammonium nitrate in groups AN4-6 inhibited the growth, and these trials had to be ended at day 6. However, no significant differences were found between the group AN2 and the control in terms of the specific growth rate, or chlorophyll a content. In the second experiment, agricultural fertilizer was used as N:P:K source. Among the experimental groups, the highest cell concentration and yield of biomass on nitrogen were determined in group AF3 (p<0.05). There were no significant differences between group AF3 and control in terms of the specific growth rate and chlorophyll a content (p>0.05). Consequently, the results demonstrate that ammonium nitrate or agricultural fertilizer can be used to culture A. platensis and to reduce the cost of producing biocompounds.
