One-column footnote within revtex package

I use revtex-4-1 package and have the following code:

documentclass[aps, twocolumn, nofootinbib, superscriptaddress, floatfix]{revtex4-1}
newcommand{myparagraph}[1]{parbigskipnoindenttextbf{#1}}
hfuzz=2.7pt
usepackage[section]{placeins}
usepackage{float}
usepackage[utf8x]{inputenc}
usepackage[T2A]{fontenc}


begin{document}
title{Document}

maketitle

myparagraph{Introduction.} abcdfootnote{adsfsfdsfdfsfsfdsffdsggdgfdgfgdfhbdbfdbsgng grsgdfkngfsvkjdfnralhkfakkkkkwfmmdghra}
end{document}

It places the footnote in two columns:

Could you please tell me how to place it in one column without changing the revtex package?
