A comprehensive scientific review published in Frontiers in Microbiology examines the emerging roles, functional performance, and practical limitations of CRISPR/Cas systems across the field of food microbial biotechnology. Conducted by researchers from the Institute of Agricultural and Food Biotechnology (IBPRS-PIB) in Warsaw, Poland, the review examines the genetic engineering of microorganisms relevant to food biotechnology. Working across the institute’s Department of Biotechnology Laboratory of Genetic Engineering and the Department of Food Safety and Chemical Analysis, the authors evaluate the current transition from basic molecular editing toward precision microbiology. A primary conclusion established in the review is that while CRISPR/Cas technologies offer unprecedented opportunities for targeted genetic alteration, experimental evidence currently varies considerably among different microorganisms and specific applications, and successful genome editing in the laboratory does not automatically translate into improved technological performance in practical food systems.
CRISPR/Cas technologies offer programmability for the genetic engineering of microorganisms relevant to food biotechnology. As detailed in the review, this programmability allows for targeted genome modification, targeted transcriptional regulation of specific genes, sequence-specific antimicrobial activity, and diagnostic nucleic acid detection. Within food processing and biotechnology, these molecular functions present researchers and industry practitioners with new strategies to refine microbial fermentation processes, enhance biological safety, and improve the functional properties of food-associated strains.
In their analysis of recent scientific literature, the authors review practical applications involving key microbial categories, specifically focusing on starter cultures, probiotic strains, and industrial production microorganisms. In addition to general metabolic and strain engineering, the review outlines emerging precision microbiology strategies aimed at conferring bacteriophage resistance to vulnerable cultures, achieving targeted pathogen and biofilm control in food processing environments, and deploying sequence-specific nucleic acid detection for rapid food diagnostics.
A central emphasis of the review is establishing a rigorous distinction between applications that have undergone experimental validation within authentic food-related settings and those that remain preliminary proof-of-concept studies conducted in laboratory media or biomedical environments.
The review systematically analyzes the principal technical barriers that currently obstruct the scale-up and industrial implementation of CRISPR-based tools in commercial food biotechnology. Among these obstacles is strain-specific editing efficiency. Furthermore, the authors identify genetic stability, process robustness, and validation in food matrices as critical hurdles.
Finally, the authors examine the distinct biosafety and regulatory implications that accompany the prospective deployment of genome-edited microorganisms in the food chain. The review draws a crucial regulatory line between production microorganisms that are completely removed or inactivated during downstream processing and viable engineered cultures that remain alive and metabolically active in final retail food products. By integrating molecular engineering capabilities with empirical evidence of functional performance, process robustness, and biosafety requirements, the authors provide a balanced assessment of both the tangible opportunities and the persistent limitations governing CRISPR/Cas applications in food microbial biotechnology.
