Optimisation of xanthan gum production by palm date (Phoenix dactylifera L.) juice by-products using response surface methodology

Date and their processing byproducts as substrates for bioactive compounds production

“…The results showed that gum concentration increased with an increase in fermentation time with a maximum yield of 0.89 g/100 mL after 96 h. The xanthan obtained showed a very similar chemical composition compared to commercial xanthan. Salah et al (2010Salah et al ( , 2012 investigated and optimized xanthan gum production by X. campestris NRRL B-1459. The results showed that this strain had a high ability to metabolize date byproducts.…”

Application of Experimental Design Method for the Optimisation of Xanthan Gum Production from Pineapple Peels Using Xanthomonas Campestris via Submerged Fermentation

“…These wastes are typically disposed of improperly particularly in less developed countries thereby causing serious environmental pollution problems. Currently, these waste materials have little or no use and they are most often used for limited purposes such as animal feed [3]. Since the waste material is rich in carbohydrate and other nutrients, it can serve as ideal substrate for the production of value added products such as xanthan gum, citric acid and bioethanol [4,5].…”

“…Amongst these strains, xanthan gum produced by Xanthomonas campestris has the most desirable properties and for this reason has gained commercial significance [6]. The structure of xanthan gum is made up of repeating units of pentasaccharide containing two molecular units of glucose, mannose and one molecular unit of glucuronic acid [3]. As a result of its outstanding rheological properties, xanthan gum finds a lot of applications as thickening, stabilizing and suspending agent in many industries such as food, cosmetics, paint, pharmaceutical, oil recovery, agriculture etc [7].…”

Evaluation of the Use of a Reflux System for Sample Preparation of Xanthan Gum and Subsequent Determination of Ca, Cu, K, Mg, Na and Zn by Atomic Spectrometry Techniques

“…The industrial production of xanthan gum, as well as its commercialization and use, have progressively increased at an annual rate of 5-10%. 4 As the salt content can affect the xanthan rheological properties, information about metals concentration (Ca, Fe, K, Mg, Na, Zn, etc.) are very important, and the appropriate and reliable method for the determination of metallic elements is necessary for a better characterization of xanthan gum samples.…”
