Chromochloris zofingiensis is a green alga that serves as valuable source of lipids, proteins, and carotenoids. Compared to well-studied microalgal carotenoid producers, C. offers several advantages, including high biomass, lipid productivity well less susceptibility contaminations. can achieve growth rates up four times higher than those H. pluvialis under optimal phototrophic conditions. Although studies have examined its cultivation carotenogenesis different tropic modes at laboratory scale, few focused on pilot-scale systems. The goal this study investigate the microalga’s physiological adaptation in 200 L tubular photobioreactor during three-phase semi-continuous strategy, particularly focusing changes macromolecular pigment composition. After an initial biomass accumulation phase, two-phased stress phase was applied combining nutrient depletion (phase 1) osmotic salt conditions 2). Following procedure, cellular protein content dropped 44.7% level, while rose by 320%. Additionally, astaxanthin concentration increased from 1.1 mg/gDW 4.9 last phases, aligning with results published laboratory-scale studies.
