| contents | Prospects and challenges in using engineered lactic acid bacteria in aquaculture applications. Huang, Xiyin Sun, Xiangze Dong, Xingya Tang, Yuzhou Xu, Shouying Wu, Yuxia Hu, Shengbiao Ren, Yichao Tu, Qiang Zhang, Youming Despite the considerable potential of lactic acid bacteria (LAB) as probiotics, there is a fundamental gap between the functional limitations of wild-type strains and the complex demands of aquaculture. Modular and intelligent engineering strategies are the primary avenues for bridging this gap. This article systematically reviews the strategies and advances in the application of genetically engineered LAB. Technologies, including clustered regularly interspaced short palindromic repeat (CRISPR)/Cas systems, Red/ET recombination, and functional modifications have significantly enhanced the targeted delivery, environmental tolerance, and multiple probiotic functions of LAB, successfully yielding engineered strains such as oral vaccine strains expressing pathogen antigens, antimicrobial peptide-high-yielding antibacterial strains, and nitrite-degrading water-improving strains. These engineered strains have demonstrated superior performance in disease prevention, growth promotion, and environmental remediation compared to wild-type strains in the farming of tilapia, shrimp, and shellfish. However, challenges, such as plasmid instability, biosafety risks, and regulatory barriers, remain unresolved. Future research should focus on multi-omics-guided precision design, development of environmentally responsive genetic circuits, and full-cycle risk assessment, promoting engineered LAB as a core solution for sustainable aquaculture through collaboration across industries, academia, and research. |
