Algal treatment using P. sumatraense AQ67100 filtrate improves the release of metabolites from C. vulgaris. a Sugars released in the incubation medium from enzymatically treated C. vulgaris cells. b, c Amount of b chlorophylls and c lipids in ethanolic extracts from enzymatically treated C. vulgaris cells. [N-T: no treatment; C-T: treatment with cellulase blend; LCS-T: treatment with lysozyme–chitinase–sulfatase blend; F-T: treatment with P. sumatraense blend; N-T/DMSO: no treatment + DMSO-extraction; RB: total lipids from raw algal biomass]. Data are expressed as mean ± SD (N ≥ 5). Asterisks indicate statistically significant difference against control (N-T) according to Student’s t test (*p ≤ 0.005; **p ≤ 0.0005; ***p ≤ 0.0001)
