From memory, carbon dioxide will kill nosema spores at slightly elevated 
temperatures (around 45°C or so). 
I haven't looked up the paper, but am sure it shouldn't be too difficult to 
track down, probably around 15-30 years ago time frame. 

The benefits of this in a shipping container would be: not corrosive, cheap, 
safe, no airing time before use... pretty much no downsides. 
Acetic acid has the propensity to rust any metal components in frames 
(wire, nails/staples etc) with the resulting food contaminant risk.
