Green coconut shells, rich in nutrients, could be an alternative substrate to obtain xanthan. This study aimed to evaluate the production and rheological properties of xanthan obtained on different fermentation scales using green coconut shells as the substrate, using its production from sucrose for comparison. Media containing minimal nutritional requirements (carbon, urea, phosphate) were prepared. Upon changing from the conventional medium to the alternative medium there was a 30% increase in production using the shaker and 81% increase using the bioreactor. Increasing the fermentation scale resulted in an increased yield of xanthan and a 30% increase in apparent viscosity. Coconut shells deserve special attention, constituting a possibility for the large scale production of xanthan with cost reduction and application of a residue.Submitted by Suelen Reis (suziy.ellen@gmail.com) on 2014-04-01T14:31:11Z No. of bitstreams: 1 10.4322polimeros.2013.094.pdf: 571375 bytes, checksum: eaab742093a99b92f78f9ec263717ec8 (MD5)Approved for entry into archive by LIVIA FREITAS (livia.freitas@ufba.br) on 2014-07-18T16:24:36Z (GMT) No. of bitstreams: 1 10.4322polimeros.2013.094.pdf: 571375 bytes, checksum: eaab742093a99b92f78f9ec263717ec8 (MD5)Made available in DSpace on 2014-07-18T16:24:36Z (GMT).
