| Abstract: | Xamthan gum was produced by using sugar-cane molasses,after the single factor and orthogonal design experiments,the optimal combinations were confirmed as followings:the content of sugar-cane molasses was 12°Bx,peptone was 8g/L,the inoculating content was 10%,initial pH was 7.5,and shaking temperature was 28℃,inoculating time was 96h.Under the optimized conditions,the Xamthan gum content was 35.28g/L,159% higher than the initial fermentation conditions. |
