Biofilm production by Zymomonas mobilis enhances ethanol production and tolerance to toxic inhibitors from rice bran hydrolysate Tatsaporn Todhanakasem; Atit Sangsutthiseree; Kamonchanok Areerat; Young, Glenn M.; Pornthap Thanonkeo (2014)
Microorganisms play a significant role in bioethanol production from lignocellulosic material. A challenging problem in bioconversion of rice bran is the presence of toxic inhibitors in lignocellulosic acid hydrolysate. Various strains of Zymomonas mobilis (ZM4, TISTR 405, 548, 550 and 551) grown under biofilm or planktonic modes were used in this study to examine their potential for bioconversion of rice bran hydrolysate and ethanol production efficiencies. Z. mobilis readily formed bacterial attachment on plastic surfaces, but not on glass ...
Fermentation of rice bran hydrolysate to ethanol using Zymomonas mobilis biofilm immobilization on DEAE-cellulose Tatsaporn Todhanakasem; Tipong Narkmit; Kamonchanok Areerat; Pornthap Thanonkeo (2015)
Background: The major challenges associated with the fermentation of lignocellulosic hydrolysates are the reduction in the operating cost and minimizing the complexity of the process. Zymomonas mobilis biofilm has been emerged to resolve these complexities. Biofilm has been reported to tolerate to the toxic inhibitors and easily manipulated toward the cell recycle through the cell immobilization. Results: Z.mobilisZM4 and TISTR 551were able to develop biofilms onDEAE cellulose under the differences in the morphologies. Z. mobilis ZM4 developed ...
