We have found a way to make possible large-scale plasmid transfection using PEI to produce high titer viral vectors in fixed bed or adherent cell culture bioreactors by using PEI as a transfection agent, while avoiding formation of the PEI-plasmid precipitate which in prior art approaches clogged adherent bioreactor substrates. We have also found a way to improve PEI-based transfection by modifying how pH and CO.sub.2 are managed during transfection.

A method of removing nitrogen-bound nitrate from at least one of groundwater, surface water, or waste water is disclosed. The method includes providing contaminant-containing water from groundwater, surface water, and/or waste water sources. The method further includes adding the contaminant-containing water to an algal photobioreactor system. The method further includes adding an alga culture to the alga photobioreactor system.
