Title Statement Continuous fermentation of acetic acid production from ethanol suing cells immobilized in calcium-alginate gel beads by Chay B. Pham and Amaya B. Mata Physical Description 207-218 figures, illustrations Summary, Etc. A continuous process for acetic acid production in a tower bioreactor was developed using ethanol and Acetobacter sp. cells immobilized in calcium-alginate gel beads. The optimum initial ethanol concentration was determined. The maximum acetic acid concentration, productivity and fermentation efficiency were achieved at an initial ethanol concentration of 40 gil and aeration rate of 1.348 vvm. Incr~ing the ethanol conc~ntration up to 70 gil and decreasing the aeration rate up ~o 0.434 vvm reduced the production of acetic acid. The process was improved with an increase iii initial ethanol and acetic acid concentrations using oxygen-enriched air at low aeration rate. The final acetic acid concentration of 3.95% (w/v) was obtained in a continuous fermentation process using 0.1 vvm oxygen-enriched air ,~nd 4.2% (w/v) ethanol concentration Subject Added Entry - Topical Term Science and technology   Acetic acid production   Calcium alginate gel beads   Acebacter sp           Physical Location           Digital Copy Not Available          Add to Book Cart  |   Download MARC
