“…For better process economics, xanthan gum can be produced from cheaper substrates with high levels of carbon. These substrates will potentially yield more xanthan gum while making the production process more economically competitive [ 12 ]. In this context, examples of inexpensive carbon sources that have been reported in the literature include whey [ 13 ], sugarcane bagasse [ 14 ], cassava bagasse [ 15 ], waste bread [ 16 ], potato waste [ 17 ], and fruit wastes [ 9 , 18 , 19 ], all geared toward the green biosynthesis of xanthan gum.…”
