Article Abstract
Minicells are anucleate cells formed through asymmetric division at the poles of most rod-shaped bacteria. They lack chromosomes and are incapable of reproduction. This confers on minicells unique biological advantages, such as a higher content of cardiolipin in the cell membrane, retention of metabolic activity from the parent cells, and a reduced nucleocytoplasmic ratio, making minicells promising for applications in synthetic biology, agriculture, and medicine. This review first outlines the formation mechanisms of minicells in various rod-shaped bacteria, along with their isolation methods and current production status. It then comprehensively summarizes the latest and powerful applications of minicells that do not focus solely on traditional drug delivery. Based on the biological characteristics of minicells, the review highlights their four major functions, including detoxification and tolerance, enrichment and microreactor, molecular encapsulation and delivery, and native structural characterization. Finally, the challenges and future prospects of minicells in biotechnological applications are discussed.

Bacterial minicells are small and chromosome-free cells that result from aberrant cell division and represent a safe alternative to live microbial applications. However, most research on minicells has focused on , with few studies exploring their development in non-model, biocompatible hosts. In this study, we engineered a -deficient (formerly and ) strain capable of producing minicells and systematically evaluated its potential as a chassis for biotechnological applications.

Double-stranded RNA (dsRNA)-based biopesticides represent promising tools for target-oriented pest and pathogen control. However, their compatibility with beneficial organisms used in biological control programs is not clear. In this study, the potential interactions between two dsRNA formulationsnaked and minicell-encapsulated (ME-dsRNA)and different commercialized bacterial, fungal, and insect biocontrol agents (BCAs) were examined.

The bacterial flagellar motor, which spins a helical propeller for propulsion, has undergone evolutionary diversification across bacterial species, often involving the addition of structures associated with increasing torque for motility in viscous environments. Understanding how such structures function and have evolved is hampered by challenges in visualizing motors in situ. Here we developed a Campylobacter jejuni minicell system for in situ cryogenic electron microscopy imaging and single-particle analysis of its motor, one of the most complex flagellar motors known, to subnanometre resolution.

Bacterial biohybrid microrobots possess significant potential for targeted cargo delivery and minimally invasive therapy. However, many challenges, such as biocompatibility, stability, and effective cargo loading, remain. Bacterial membrane vesicles, also referred to as minicells, offer a promising alternative for creating sub-micron scale biohybrid swimmers (minicell biohybrids) due to their active metabolism, non-dividing nature, robust structure, and high cargo-carrying capacity.
