Special Issue Information

Dear Colleagues,

Microbial communities comprising bacteria and fungi are immense treasure troves for producing the most promising biologically active natural products. Out of the approximately half-million known natural products, around 70,000 are derived from bacteria and fungi, with nearly half (approximately 33,500) having had their bioactivities characterized. These natural products serve as drug leads for the pharmaceutical arsenal and contemporary medicine; however, the rediscovery of known chemical skeletons has emerged as an impediment to discovering novel natural products with diverse bioactivities. Moreover, the growing prevalence of multidrug-resistant pathogens represents a critical threat to global public health. This underscores the urgent need for the discovery of novel bioactive natural products derived from microorganisms. Remarkably, genome sequencing and bioinformatic analysis unveiled that only a very small fraction of the biosynthetic potential of microorganisms has been realized. The number of cryptic biosynthetic gene clusters (BGCs) that remain uncharacterized is immense. This Special Issue of Microorganisms is dedicated to gathering new insights into the microbial synthesis of natural products and their potential applications, spanning novel microbial natural product discovery, the elucidation of the biosynthetic logic of microbial compounds, and their promising bioactivities. We welcome submissions consisting of reviews, original research articles, and communications.

Corynebacterium glutamicum is a versatile microbial cell factory, but efficient recovery of intracellular macromolecules remains a major challenge. In this study, we engineered environmentally controllable lysis systems to enable programmable product release. A glucose-responsive module, combining the cg3195 promoter with phage-derived holin–endolysin genes (clg51-50), triggered lysis when extracellular glucose dropped below 0.19–0.36 g/L. A separate temperature-inducible system employing the cI857-CJ1OX2 module activated lysis at 42 °C. These modules were further integrated into a dual-input AND-gate circuit, enhancing regulatory precision and suppressing premature lysis, with additional operator copies allowing temporal tuning of induction. Functional validation using fluorescence, cell density measurements, and scanning electron microscopy confirmed robust, tunable responses under defined environmental cues. Collectively, these programmable lysis systems demonstrate that stimulus-responsive genetic circuits can be rationally designed to control cell disruption, providing a promising approach to streamline downstream processing and reduce extraction costs in industrial fermentation of Corynebacterium glutamicum.
