The present invention relates to methods for preventing or removing biofilm on a surface, comprising contacting the surface with an effective amount of a composition comprising one or more acylases and a carrier to degrade a lactone produced by one or more microorganisms, wherein the degradation of the lactone prevents or removes the biofilm. The invention also relates to a method for producing this interference pigment and to the use thereof. The distance between each sample on the dynamic pressure waveform and the corresponding sample on the calculated line is determined. The MOS can have a source coupled to the programmable resistive element, a bulk coupled to a drain, a drain coupled to a second supply voltage line, and a gate coupled to a third supply voltage line.
