Does anyone where I could get the bacterial strain of Pseudomonas 
chlororaphis that lacks the N2O reductase capacity? The ATCC # is 43928 
but is not currently available from ATCC. Alternatively, does anyone 
know are there any other strains that could be used in the 
"denitrifier"-method that is used in 15NO3 analyzes?

Best regards,
