The present invention relates to isolated nucleic acid sequences encoding polypeptides having haloperoxidase activity. Apparatus for effecting this adsorption method and apparatus in which regeneration conditions are modified based on the actual ambient water content of the feed gas are also disclosed. The swirling air is additionally used to purge agglomerated powder particles from the charging electrodes in the charging chamber. The SRM module allocates a media conference to a first DSP and a second DSP and sets the media conference to the active mode in the first DSP and a stand-by mode in the second DSP. The time constants for the low pass filtering performed by the microcontroller can be dynamically adjusted dependent upon sudden changes in the instantaneous leak flow. The capacitor provides additional current during high demand intervals.
