Fibres in the micro- and nanometre scale are suited to a broad range of applications, including drug delivery tissue engineering. Electrospinning is manufacturing method choice, but it has some limitations. Novel pressure-driven fibre-forming techniques, like pressurised gyration (PG), overcome these limitations; however, compatibility PG with biological materials not yet been evaluated detail. For first time, this limitation was investigated by optimising for microbial cell processing incorporating bacterial cultures into fibrous polymeric scaffolds sustained release. Multiple polymer–solvent systems were trialled, polyvinylpyrrolidone (PVP)/phosphate-buffered saline (PBS) 25% w/v, polyethylene oxide (PEO)/PBS 20% PVP/ethanol w/v. Rheological studies revealed surface tension PVP/PBS, PEO/PBS, be 73.2, 73.9, 22.6 mN/m, respectively. Scanning electron microscopy showed median fibre diameters between 9.8 μm 26.1 μm, PVP producing larger fibres. Overnight Bacillus subtilis then incorporated chosen solutions processed fibres using PG. The produced cell-loaded incubated LB broth assess viability encapsulated cells. Colony counts post-incubation PVP/PBS resulted 60% growth, PEO/PBS led 47% whereas did lead any growth. Based on results gathered during study, can concluded that offers promising way encapsulating cells other sensitive products while having many notable advantages compared electrospinning. This research demonstrates proof concept research-based evidence showcases potential as key disruptive innovation probiotic system design manufacturing.

Abstract Electrospinning and pressurized gyration are two widely adopted methods for polymeric fiber production, valued their simplicity, versatility, relatively low environmental impact. Despite its advantages, electrospinning has notable limitations, including production efficiency significant safety concerns. Pressurized gyration, however, offers greater productivity a safer, more sustainable process, making it an excellent candidate industrial scaling. To fully realize this potential, optimizing the process is essential enhancing achieving large‐scale production. In study, effects of vessel orifice height on rate morphology in explored. A series experiments conducted using 15 wt.% polycaprolactone (PCL) solution, with vessels identical diameter but differing heights 7.5, 15, 22.5 mm tested under pressures 0, 0.1, 0.2, 0.3 MPa, all at constant rotational speed 13 000 rpm. The 7.5 demonstrates highest pressure while increasing led to finer diameters, better alignment, smaller beads. These findings underscore importance design, along solution parameters, scaling up manufacturing meet demands.
