PHY-Oxylimited-SpaBCTS

The subtilisin production module is mediated by a hypoxic promoter and functions through a gene cluster composed of SpaBCTS. The population of engineered Bacillus subtilis keeps growing in the cracks, consuming oxygen, and at the same time, the engineered bacteria penetrate deep into the tiny cracks, and the environment lacks oxygen, thus realizing hypoxic conditions, and the subtilisin production module is activated. However we failed to convince the function as the bacteria could only express the first protein under oxygen limitation environment.

Applications of BBa_K4202007

we transformed it into our chassis-Bacillus subtilis for further protein expression. 50ml shaking flasks with 5ml culture media were introduced to reach an extra-large bacterial population while the normal 12ml shaking bacteria tubes were used as control. From the SDS-PAGE image, we could see a clear strip locating in 120kDa’s area for the 50ml shaking flasks group, revealing the excellent function of Oxygen-limitation induced promotor. However, it seemed that only the first gene (SpaB,120kDa) had expressed under the condition, suggesting that the original sequence didn’t match well to the promotor.
