Optimization for Microbial Degumming of Ramie with Bacillus subtilis DZ5 in Submerged Fermentation by Orthogonal Array Design and Response Surface Methodology

As a kind of natural fiber, ramie fiber has distinctive advantages in textile application, but the application is limited due to the traditional degumming mode. Compared with the traditional degumming process, the microbial degumming process has many advantages. To obtain the optimal conditions for degumming ramie with Bacillus subtilis DZ₅(BSDZ₅), a combined statistical approach of orthogonal array design(OAD) and response surface methodology(RSM) was used. The influences ...
