摘要
The use of the enzyme mirosinase, extracted from Brassica rapa L. ', in the delignification of chips and in refining and bleaching the brown stock pulp of Eucalyptus and pine.The present invention relates to an enzymatic pretreatment with enzyme mirosinase extracted from 'Brassica rapa L' (turnip long), in the kraft pulping of wood chips of Eucalyptus and Pinus.And in the drainability of the pulp brown. The biocatalyst reveals the enzyme mirosinase as possible additive use be used in conventional kraft pulping and bleaching, refining.In industrial scale, the use of this product, extracted from natural source, renewable and non polluting.Brings significant reduction in environmental impacts generated by effluent from pulp and paper factories.The results of laboratory tests suggest that the application of the enzyme mirosinase into chips (pulping).And in the pulp Brown (refining) brings significant gains in terms of income (%) of purified pulp obtained.Depending on the variables of the process employed, significant gains in the indexes of refining of pulp Brown (pine), and the rates of arrebentamento.
