Pulp and paper industry wastewater treatment: use of microbes and their enzymes

Abstract: AbstractPulp and paper industry is coming under one of the most water polluting industries, and generated wastewater is highly toxic in nature. The paper mill requires huge quantity (~50–60 m3 of water to produce one ton of paper) of water, and accordingly huge quantity of chemical contaminated wastewater is discharged. The paper mill effluents have identified 240–250 chemicals in different stages of paper making. Various chemical constituents such as high … Show more

“…16 To address this concern, new bio-catalysis-mediated remediation strategies involving enzymes are currently being explored as environmentally friendly approaches to remove toxic wastewater pollutants. 17,18 Laccase has great potential as a multi-task biocatalyst in the entire papermaking process. The enzyme can be used alone or in combination with other bleaching enzymes for pulping or the delignification of pulp.…”
