Table 6. Composition of samples for appropriate concentration of natural pigments for viable assay.

MP % (W/V)	0.3	0.5	0.6	0.7	0.8	0.9	1	1.5	2	3
AP % (W/V)	0 (control)	0.05	0.1	0.2	0.3	0.5	1	1.5	2	3

Notes.

Total volume of sample : 1 [mL] (Solvent is CM medium.).

Initial cell density : 4.0 × 10⁵ [cells/mL].

(Cells were cultured for 4 days before pigment was mixed and observed for 6 days).
