Abstract
Disclosed is a preparation method for bio-fuel materials and bio-chemicals comprising the following steps: preparing a medium comprising fermentation waste generated in an alcohol production process; inoculating a first microorganism into the medium; and culturing the medium wherein the first microorganism was inoculated. More specifically, the preparation method for bio-fuel materials and bio-chemicals comprises the following steps: fermenting hexoses from a mixture of pentoses and hexoses to produce an ethanol fermentation broth; separating and purifying the ethanol fermentation broth; preparing a medium comprising the fermentation waste produced in the separation and purification step; inoculating a first microorganism into the medium; and culturing the medium wherein the first microorganism was inoculated.
