soluble starch

In 1896, Beijerinck first noted an 'incompatibility' in solutions of agar, a water-soluble polymer, with soluble starch or gelatine.

Today mostly modified carboxymethylated cold soluble starches are used which have a stable viscosity and are easier to rinse out of the fabric and give reproducible "short" pasty rheology.

It is made by adding 3 grams of soluble starch to 1 liter of heated water; the solution is cooled before use (starch-iodine complex becomes unstable at temperatures above 35 C).

This species is able to use sucrose, maltose, cellbiose, trehalose, raffinose, citrate, inositol ethanol, soluble starch, melezitose, xylitol, saccharate, salicin as well as many other compounds as sole carbon sources.

C. antarcticus is not able to ferment, but all of its strains use cellobiose, 2-ketogluconate in hemicalcium salt, gluconate at pH 5.8, glucuronate at pH 5.5, maltose, mannitol, melezitose, soluble starch and succinate at pH 5.5 as sole carbon sources.
