Compositions comprising enzyme compositions are provided. Also provided are methods of treating virgin fiber and recycled wastepaper containing mineral oils using the compositions comprising enzyme compositions. The mineral oils generally originate from wastepapers with mineral oil based inks and certain other hydrocarbon-based chemistries used during the manufacturing, paperboard converting, and packaging process. The enzymes break down or modify mineral oils present in the fiber and paper, mobilize and liberate them from the fibers, and increase removal of mineral oils during paper recycling, pulping and papermaking processes.
