Medium relevanceA three-stage culture process for improved exopolysaccharide production by Tremella fuciformis.
Tremella fuciformis
Key points
- Tremella fuciformis produces several bioactive secondary metabolites including exopolysaccharides
- Cultivation of the fungus was carried out in a three-stage process consisting of a 1.5-day cultivation with orbital shaking at 200 rpm, a 1.5-day cultivation with reciprocal shaking at 200 strokes, and a 1.5-day cultivation with orbital shaking at 200 rpm
- Exopolysaccharide production and specific production rate reached 5.80 g L(-1) and 0.15 d(-1), respectively, which is an increase of 260% and 200% compared with the corresponding values for fermentations with orbital shaking only, and of 243% and 150% compared with the corresponding values for fermentations with reciprocal shaking only
- The three-stage culture method is time-saving and easy to operate
