Production of Gardenia Blue Color from Gardenia Waste by the Bacillus subtilis

Bacillus substilits에 의한 치자황색소 부산물로부터 치자청색소의 생산

For waste recyle, we were investigated on Gardenia blue color production using Gardenia by-product by Bacillus subtilits. Optimum conditions for producing blue pigment were found to be 30$^{\circ}C$, initial pH 6.5, glucose as a carbon source 3% and yeast extract as a nitrogen source 0.5%, respectively. Optimum conditions for fermentor culture were agitation speed 400rpm, aeration 2 vvm and inoculum 5%. The optimum perculture time for inoculum was 20 hrs for blue pigment production.
