DIG-L: Potassium Toxicity to Methanogens

["OLEL" <olel@vsnl.net>]

Dear All,

 

I am aware that 50% inhibition concentration of Potassium for the methanogenic bacteria is 6100 mg/L.

Can somebody tell me , where can I find this fact/value in a 'Technical Publication', preferably on the net ?

Thanks,
