Studies on Fermentation of Monascus Purpureus TISTR 3090 With Bacterial Cellulose From Acetobacter Xylinum TISTR 967

Bacterial cellulose produced by Acetobacter xylinum TISTR 967 was fermented by Monascus purpureus TISTR 3090 in culture medium on a rotary shaker at 150 rpm, 30 ˚C for 12 days. Sucrose concentration of 5% (50 g/l), ammonium nirate concentration of 1.5%, initial pH at 5.5 and a temperature at 30 ˚C resulted in the production of an appealing bright red color. The color stability study was carried out using a medium composed of 5% sucrose, 1.5% ammonium nitrate and initial pH 5.5 for fermentation at 30 ˚C for 12 days. Products demonstrated good resistance to washing, heat, freezing, acidification and irradiation.
