Biochemical composition, β-glucan and phenolic content of a marine diatom <i>Chaetoceros muelleri</i> cultivated in Guillard's modified medium.

ABSTRACT: The biochemical compositions of diatoms are important for agricultural and pharmaceutical applications, and they vary according to nutrients and physical factors. To study the influence of carbonate and nitrogen source supplementation in the medium on the chemical composition of the marine diatom Chaetoceros muelleri, Guillard's medium was modified for this study. Three types of Guillard medium were prepared including standard Guillard medium (T1), modified Guillard medium (0.005 g/L bicarbonate supplement, T2), and 50% nitrogen reducing medium (T3). Results showed that the maximum biomass was observed at T3 (5.75 × 10⁶ cell/mL), which was significantly different (p < 0.05) from that at T1 (3.85 ± 0.13 × 10⁶ cells/mL) but did not differ from that at T2 (
