Batch fermentations (28 °C/250 rpm /120 h) were carried out using crude glycerin, 0.01% urea and 0.1% KH2PO4, (% w/v), and compared to a sucrose control under the same operational conditions, using Xanthomonas campestris strain 2103 isolate from Brazil. Its maximal production by crude glycerin fermentation was 7.23±0.1 g·L-1 at 120 h, with an apparent viscosity of 642.57 mPa·s, (2 % w/v, 25 °C, 25 s-1), 70% and 30% higher than from sucrose fermentation, respectively. Its molecular weight varied from 28.2 to 36.2×106 Da. The Ostwald-de-Waele model parameters (K and n) indicated a pseudoplastic behavior at all concentrations (0.5 to 2.0 %, w/v) and temperatures (25-85 °C), while its consistency index indicated promising rheological properties for drilling fluid applications. Therefore, crude glycerin has potential as a cost-effective and alternative substrate for non-food grade xanthan production.Submitted by Suelen Reis (suziy.ellen@gmail.com) on 2014-04-29T13:53:35Z No. of bitstreams: 1 0104-66322013000400006.pdf: 323743 bytes, checksum: be46d44ac9517222f4d5a8b7c11c0dcb (MD5)Approved for entry into archive by LIVIA FREITAS (livia.freitas@ufba.br) on 2014-07-10T19:25:02Z (GMT) No. of bitstreams: 1 0104-66322013000400006.pdf: 323743 bytes, checksum: be46d44ac9517222f4d5a8b7c11c0dcb (MD5)Made available in DSpace on 2014-07-10T19:25:02Z (GMT).
