| Title | Inducible expression of trehalose synthase in Bacillus licheniformis. |

| Abstract |
Trehalose synthase (TreS) could transform maltose into trehalose via isomerization. It is a crucial enzyme in the process of trehalose enzymatical transformation. In this study, plasmid-based inducible expression systems were constructed to produce Thermomonospora curvata TreS in B. licheniformis. Xylose operons from B. subtilis, B. licheniformis and B. megaterium were introduced to regulate the expression of the gene encoding TreS. It was functionally expressed, and the BlsTs construct yielded the highest enzyme activity (12.1 U/mL). Furthermore, the effect of different cultural conditions on the inducible expression of BlsTs was investigated, and the optimal condition was as follows: 4% maltodextrin, 0.4% soybean powder, 1% xylose added after 10 h of growth and an induction time of 12 h at 37 °C. As a result, the maximal yield reached 24.7 U/mL. This study contributes to the industrial application of B. licheniformis, a GRAS workhorse for enzyme production. |
