Abstract

The fermentation conditions for the maximal production of the useful polysaccharides(water soluble polysaccharide and cell bound polysaccharide) from marine bacterium Zoogloea sp.(KCCM 10036) were investigated with a 5 L jar fermentor. The maximal production of these polysaccharides was obtained under the conditions of initial pH 7.8, 30$^{\circ}C$, 400 rpm of agitation speed, 2 Wm of aeration rate, 10%(w/v) of inoculum size and 2.5%(w/v) of glucose substrate and 10.38 g/L of total polysaccharide was produced. Apparent viscosity of the culture broth was increased with the production of these polysaccharides and the maximum value was reached to 22,500 cp.
