The fast growth accompanied with high substrate consumption rates and a versatile metabolism paved the way to exploit Vibrio natriegens as unconventional host for biotechnological applications. Meanwhile, a wealth of knowledge on the physiology, the metabolism, and the regulation in this halophilic marine bacterium has been gathered. Sophisticated genetic engineering tools and metabolic models are available and have been applied to engineer production strains and first chassis variants of V. natriegens. In this review, we update the current knowledge on the physiology and the progress in the development of synthetic biology tools and provide an overview of recent advances in metabolic engineering of this promising host. We further discuss future challenges to enhance the application range of V. natriegens.

Erlenmeyer shake flasks are widely used during the first steps of bioprocess development. Despite their broad application in academia and industry, shake flasks usually lack standardized and user-friendly online monitoring techniques. In this work, the pH and Respiratory Activity MOnitoring System (pH-RAMOS) for the non-invasive online measurement of the oxygen transfer rate (OTR), carbon dioxide transfer rate (CTR), and pH in up to eight parallel shake flasks under sterile conditions is presented.

Bioproduction of chemicals by using engineered bacteria is promising for a circular economy but challenged the instability of the introduced plasmid by conventional methods. Here, we developed a two-plasmid INTEGRET system to reliably integrate the targeted gene into the genome, making it a powerful strain for efficient and steady bioproduction without requiring antibiotic addition. The INTEGRET system allows for gene insertion at over 75% inserting efficiency and flexibly controllable gene dosages.

Article Synopsis
- The successful production of industrial natural products relies on strong microbial systems and reliable genetic tools to express target genes effectively.
- The study combines the σlac and tet expression systems into one plasmid to evaluate their effectiveness in producing fluorescent reporters and terpenoids like lycopene and β-carotene in various bacteria.
- Improvements in the expression systems, particularly by adding toehold switches for better control, enhance the production of biosynthetic intermediates, showing potential for advanced genetic tool applications.

Recently, clean PET biodegradation has gained widespread attention in tackling white pollution. Nonetheless, the development of industrial biotechnology is still impeded by its contamination susceptibility, high energy input, and consumption of substantial freshwater resources. Thus, a novel PET biodegradation process was developed based on host screening and by-product circulation to address the aforementioned issues.
