Advances in research on microbial conjugated linoleic acid bioconversion
Conjugated linoleic acid (CLA) is a functional food ingredient with prebiotic properties that provides health benefits for various human pathologies and disorders. However, limited natural CLA sources in animals and plants have led microorganisms like Lactobacillus and Bifidobacterium to emerge as new CLA sources. Microbial conversion of linoleic acid to CLA is mediated by linoleic acid isomerase and multicomponent enzymatic systems, with CLA production efficiency dependent on microbial species and strains. Additionally, complex factors like LA concentration, growth status, culture substrates, precursor type, prebiotic additives, and co-cultured microbe identity strongly influence CLA production and isomer composition. This review summarizes advances in the past decade regarding microbial CLA production, including bacteria and fungi. We highlight CLA production and potential regulatory mechanisms and discuss using microorganisms to enhance CLA content and nutritional value of fermented products. We also identify primary microbial CLA production bottlenecks and provide strategies to address these challenges and enhance production through functional gene and enzyme mining and downstream processing. This review aims to provide a reference for microbial CLA production and broaden the understanding of the potential probiotic role of microbial CLA producers.
期刊介绍：
The significance of lipids as a fundamental category of biological compounds has been widely acknowledged. The utilization of our understanding in the fields of biochemistry, chemistry, and physiology of lipids has continued to grow in biotechnology, the fats and oils industry, and medicine. Moreover, new aspects such as lipid biophysics, particularly related to membranes and lipoproteins, as well as basic research and applications of liposomes, have emerged. To keep up with these advancements, there is a need for a journal that can evaluate recent progress in specific areas and provide a historical perspective on current research. Progress in Lipid Research serves this purpose.
