Multi-parameter optimization of recombinant protein secretion in Bacillus subtilis: a review.
Review in Microbial cell factories, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Bacillus subtilis is widely recognized as one of the most robust and versatile hosts for recombinant protein production. This review provides a comprehensive overview of the protein secretion pathway in B. subtilis, detailing its mechanistic basis and key limiting steps. We discuss the structural features of signal peptides (SPs) that govern efficient translocation and highlight recent advances in de novo promoter and signal peptide engineering. A particular focus is placed on the integration of artificial intelligence (AI) to predict and design optimal genetic elements. Drawing on findings from combinatorial and multi-parameter studies, we propose that future engineering strategies should move beyond maximizing individual parameters. Instead, achieving a dynamic balance across transcriptional, translational and secretion layers is essential to sustain high productivity while minimizing cellular secretion stress. This review offers a roadmap for systems-level engineering of B. subtilis as a next-generation protein production platform.
