To achieve efficient co-production of polysaccharides and phycoerythrin of Porphyridium purpureum in a 40 L stirred tank photobioreactor, a strategy of stepwise increasing irradiance and adding glycerol was proposed after optimization of environmental factors for microalgae growth. The results showed that the optimal temperature and NaCl concentration were 25 °C and 25 g L-1, respectively. In addition, 100 and 13 μmol m-2 s-1 were identified as the optimal incident light intensity and volume-averaged light intensity, respectively. Among the four different culture strategies, compared with the traditional photoautotrophic culture with constant light intensity, the production of biomass, polysaccharides, and phycoerythrin were enhanced by 266.38%, 390.24%, and 61.76% under mixotrophic culture with stepwise increasing light intensity, respectively. The result demonstrated that the combination of glycerol supplementation and increased light intensity had a synergistic effect. Moreover, the production costs of polysaccharide and phycoerythrin decreased by 78.42% and 34.57% compared to the typical culture method (photoautotrophic culture with constant light intensity). The strategy of mixotrophic culture with stepwise increasing light intensity not only enhanced the productivity of biomass and active substances, but also reduced production costs. © 2025 Society of Chemical Industry.

Long chain polymers are reported to be effective in reducing drag in turbulent flow systems. However, most of the effective polymers are synthetic, which are costly, non-biodegradable, and toxic that raises environmental concerns. Natural polymers, as eco-friendly alternatives, are gaining interest as drag-reducing additives (DRA), but single natural polymers have lower drag reduction (DR) efficacy compared to synthetic ones and degrade under high shear stress. This study aims to investigate biopolymer complexes from hibiscus leaves (HL) and okra (OK) as eco-friendly DRAs, comparing their performance with individual components. Biopolymers were extracted from dried hibiscus leaves and okra and diluted to concentrations of 200–1000 ppm. Complexes were formulated by mixing 200–1000 ppm HL extract with 1000 ppm OK extract. The extracts were characterized using Fourier Transform Infrared Spectroscopy (FTIR), meanwhile all the drag reducing solutions were assessed for viscosity, viscoelasticity and DR performance using an oscillating rheometer under different shear rate (0 – 200 s -1 ) and frequencies (0 – 100 Hz). All the polymer solutions showed non-Newtonian shear-thinning behavior. The biopolymers and their complexes also exhibited significant viscoelastic properties which is important for DRA stability in turbulent flow. OK solutions achieved up to 79% DR at 1000 ppm, while HL solutions reached an average of 99% DR at concentrations of 400 ppm and above. However, HL-OK complexes had lower DR efficacy, with a maximum DR of 72% at 800 ppm HL – 1000 ppm OK. This might be due to the high concentration altering the water's properties and increasing viscosity, which increases drag.In conclusion, HL and OK complexes have potential for drag reduction, but future research should optimize concentration ratios, test over a broader range of shear rates, and explore other natural polymers complexes to achieve the synergistic effect.
