Effect of Different Carbon Sources on the Extra-cellular Polysaccharide Production by <i>Tremella cinnabarina</i> in Submerged Culture
Keywords:T. cinnabarina, extra-cellular polysaccharide, emulsifier, fatty acids
The effect of fatty acids, emulsifiers and plant oils were studied with respect to their potential to support the growth and extra-cellular polysaccharide production of Tremella cinnabarina in submerged culture. The extra-cellular polysaccharide (EPS) production and mycelial growth were substantially increased by supplementation with certain fatty acids in the medium. Oleic acid, sorbitan mono-oleate and grape-seed oil significantly enhanced EPS production which were 1.5, 1.6 and 1.3 folds, respectively, in comparison to the control. In case of lipids, the results indicated that the extent of stimulation or inhibition was associated with the types and levels of lipids. However, when lipids were used as sole carbon source, poor growth and lack of EPS production were observed.
Key words: T. cinnabarina; extra-cellular polysaccharide; emulsifier; fatty acids
