Co-Culture of <i>Auxenochlorella protothecoides</i> and <i>Serratia liquefaciens</i> Promotes Lutein Accumulation.

ABSTRACT: Lutein, a crucial carotenoid with diverse biological roles, is in high demand in the market. Current production predominantly relies on plant extraction, which is hindered by low yield and seasonal limitations. Microalgae, such as Chlorella and Chlamydomonas, known for their efficient lutein production due to high photosynthetic efficiency, rapid growth, and ease of cultivation, still require enhanced yields. This study presents a novel finding that co-cultivating A. protothecoides with S. liquefaciens significantly boosts lutein production. Optimization of carbon and nitrogen sources, nitrogen-to-phosphorus (N:P) ratio, and algal-bacterial inoculation ratio using BG11 medium was systematically conducted. The results indicate that supplementing with 3.0 g/L sodium acetate as
