Application

Application Comment Organism
degradation enzymatic treatment of kraft pulp with xylanase and laccase decreases the amount of chlorine needed for bleaching. Pretreatment of pulp followed by a chemical treatment with 3% NaOCl gives the same results as with chemicals at 7% NaOCl, resulting in 42% reduction in chlorine consumption Thermomyces dupontii
