CHEMISTRY OF THE PROCESS 207 



And this would be deaminized : 



CHsSOsH CH 2 S0 3 H CH 2 SO 3 H 



| H | OH 



2C/ + O 2 = C/ = 2C = O + 2NH 3 

 |\NH 2 |\NH 2 | 



COOH COOH COOH 



In any case the resulting ammonia would be fixed within the soil 

 by the zeolites, acid radicals, or lost through volatilization. That 

 which is retained in the soil is later taken up by plants or trans- 

 formed by bacteria into protein or nitrate nitrogen. 



For each molecule of ammonia formed there would result a corre- 

 sponding molecule of volatile acid, or oxy-acid, or else of alcohol 

 which may serve as a source of carbon for other microorganisms, 

 possible for the azofiers.
