Xylose isomerase Bacillus coagulans/Streptomyces rubiginosus/Streptomyces phaechromogenes EC 5.3.1.5 ● Since these isomerases belong to the group of metalloenzymes, Co 2+ and Mg 2+ are required. ● The reaction enthalpy is slightly endothermic and reversible. The equilibrium conversion is about 50 % at 55 °C. ● To limit byproduct formation, the reaction time must be minimized. This can be done economically only by using high concentrations of immobilized isomerase. ● Several reactors are operated in parallel and contain enzymes of different ages. The feed to a single reactor is controlled by the extent of conversion in this reactor. ● The feed syrup has to be highly purified (filtration, adsorption on charcoal, ion exchange) to prevent fast deactivation and clogging of the catalyst bed (for first part of process see page 334). ● Plants producing more than 1,000 t of HFCS (high fructose corn syrup) (based on dry matter) per day typically use at least 20 individual reactors. ● The product HFCS contains 42 % fructose (53 % glucose) or 55 % fructose (41 % glucose) (as dry matter). ● Glucose isomerases have half-lives of more than 100 days. To maintain the necessary activity the enzyme is replaced after deactivation to about 12.5 % of the initial value. ● The reaction temperature is normally above 55°C to prevent microbial infection although enzyme stability is lowered. 509
