| Summary: | Itaconic acid (IA) is a high-value platform chemical with broad industrial applications, ranging from bioplastics to pharmaceuticals. Traditionally produced through fermentation using Aspergillus terreus, recent years have seen increased interest in developing sustainable, bio-based production methods. This systematic review analyzes 49 peer-reviewed studies published over the past five years, focusing on microbial IA biosynthesis using wild-type and genetically engineered strains. Among these, Yarrowia lipolytica has emerged as a promising host organism, with metabolic engineering efforts achieving titers up to 130.5 g/L, particularly when combined with optimized fermentation media and process conditions. In addition to strain improvement, advances in co-culture strategies and downstream recovery techniques—such as reactive extraction and membrane filtration—have demonstrated the potential to reduce purification costs by up to 30% while maintaining high productivity. Despite these developments, several bottlenecks remain. Substrate heterogeneity, byproduct inhibition, and challenges associated with oxygen transfer and medium viscosity limit microbial efficiency, especially in non-sterile or large-scale environments. Moreover, many studies are confined to laboratory-scale setups and often report fermentation parameters inconsistently, impeding reproducibility and scalability. To overcome these limitations, future research should emphasize the standardization of protocols and integration of holistic bioprocess designs, which are essential for transitioning IA production from research to industrial implementation. |
