Fungal laccase: properties and activity on lignin

The sources of ligninocellulose that occur in various forms in nature are s o vast that they can only be compared to those of water. The results of sev eral, mon recent experiments showed that laccase probably possesses the big ability for "lignin-barrier" breakdown of ligninocellulose. The degradatio n of this compound is currently understood as an enzymatic process mediated by small molecules, therefore, this review will focus on the role of these mediators and radicals working in concert with enzymes. The fungi having a versatile machinery of enzymes are able to attack directly the "lignin-bar rier" or can use a multienzyme system including "feed-back" type enzymes al lowing for simultaneons transformation of lignin and carbohydrate compounds .
