  Abstract

In this study, the reduction of indigo to leuco-indigo by glucose was improved by the use of enzymes, such as glucose oxidase (GOD) and laccase (LAC). In fact, indigo received electrons from the glucose oxidation reaction or the glucose degradation via intermediates resulting in production of leuco-indigo. For indigo reduction involving GOD or LAC, the redox centers of GOD and LAC act as electron carriers from the reduced glucose or transfer electrons directly to indigo molecules. Thus, the turnover rate of electron flow between glucose and indigo by means of these enzymes was increased and improved leucoindigo production, by about 25 times the rate without enzymes. Enzymatically reduced indigo was applied to the dyeing of ramie fabric.
