Traditional BD synthesis methods rely on chemical processes, which are costly and environmentally impactful. Therefore, developing a more sustainable and economical biosynthetic pathway is crucial for BD production. This study aimed to achieve efficient production of BD. Firstly, the catalytic performance of 17β-hydroxysteroid dehydrogenase and 3-ketosteroid-Δ<sup>1</sup>-dehydrogenase was improved through enzyme engineering, and their expression in the new strain of <i>Mycobacterium neoaurum</i> was enhanced using metabolic engineering. These improvements significantly increased BD production to 4.05 g/L, with a significant decrease in by-product generation. To further increase the yield, a multi-enzyme fusion expression system was constructed, and a key cell wall gene <i>kasB</i> was knocked out, resulting in a spatial-time yield of BD reaching 1.02 g/(L·d). Subsequent optimization of the transformation system further increased the BD production to 5.56 g/L, with a spatiotemporal yield of 1.39 g/(L·d).

In this study, we utilized a CHO genome scale model to first deeply characterize the intracellular metabolic states of CHO cells cultured in different combinations of basal and feed media to understand the traits of asparagine/aspartate-dependent and glutamate-dependent feeds.
