PENGARUH KETERSEDIAAN OKSIGEN PADA PRODUKSI EPIGLUKAN OLEH EPICOCCUM NIGRUM MENGGUNAKAN MEDIA MOLASES
ABSTRACT: The compound
β-glucan is a polymer of glucose, which is polymerized through beta glycoside
bond. The compound β-glucan has anti-tumor benefits, reducing the risk of heart
disease, lowering cholesterol and so forth. The compound β-glucan can be
produced by the fungus in ukstraseluler. One of the molds that can produce
compounds in the extracellular β- glucan is Epicoccum nigrum, often called
epiglucan. The purpose of this study was to determine the effect of aeration
and oxygenation to the production epiglukan by Epicoccum nigrum in molasses media.
This research was conducted using descriptive method with 3 under controlled conditions
: anaerobic, aeration and oxygenation in the Stired Continuous Tank Reactor
(batch culture). The parameters observed were the biomass (g / L), epiglucan
(g/L), reducing sugar content (%) and pellet diameter are formed. Biomass and
highest epiglikan obtained inoxygenated conditions which amounted to 7.074 g /
L and 2.01 g / L. The resulting biomass pellet-shaped with the largest diameter
occurs in conditions of oxygenation that is 0.37 mm. residual reducing sugar at
the end of fermentation the greatest there is in the anaerobic condition is
1.529%
