Abstract: A method for the degradation of lignocellulosic material by applying to the material an enzyme composition which is a mixture comprising at least a cellulase, xylanase and ligninase, and optionally other enzymes, such as a protease, lipase, urease, uricase, and/or pectinase, to solubilise or decompose the material at least partially. The method may be used for removing a biological deposit from a surface or location on or in which it is undesirably deposited. Typical deposits include human or animal faeces, bird droppings, and leaves. The cellulase, xylanase and ligninase component may be obtained as a mixture by cultivating a White Rot fungus, preferably using cattle dung, or a liquid extract, as an inducer.

Abstract: An enzyme mixture, suitable for removal of dung from animal skins and farm buildings, is prepared by cultivating white rot fungi under conditions that induce formation of a significant amount of laccase, and provide a mixture of the three enzymes cellulase, xylanase and laccase (ligninase).
