Our evolving understanding on the mechanisms underlying the health-promoting attributes of probiotic lactobacilli, together with an expanding genome editing toolbox have made this genus an ideal chassis for the development of living therapeutics. The rising adoption of CRISPR-based technologies for prokaryotic engineering has demonstrated precise, efficient and scalable genome editing and tunable transcriptional regulation that can be translated into next-generation development of probiotic lactobacilli with enhanced robustness and designer functionalities. Here, we discuss how these tools in conjunction with the naturally abundant and diverse native CRISPR-Cas systems can be harnessed for Lactobacillus cell surface engineering and the delivery of biotherapeutics.
