Carbohydrate and protein accumulations of (a) Chlorella SDEC-11 and (b) Scenedesmus SDEC-13 cultivated under phytohormones. Mass ratio is the ratio of carbohydrate and protein. The run names on the abscissas indicate the phase at which hormones were added and the culture medium; e.g., B⁺ADE-KW, indicates that phytohormones were added to algae cultured with ADE-KW at the batch cultivation phase. *Data in the same parameter marked with different letters are significantly different by Duncan’s test at p < 0.05
