Studied specialized microbial transformations from ammonia through nitrite to nitrate and growth using inorganic substrates, helping explain microbial roles in soil nutrient cycling.
Scientific scope
Studied specialized microbial transformations from ammonia through nitrite to nitrate and growth using inorganic substrates, helping explain microbial roles in soil nutrient cycling. Scope limitation: This is the 1890–1891 research series as documented in an institutional historical account; the complete original memoirs were not read. Schloesing, Muntz and Warington retain earlier biological and two-stage observations. Historical separation of stages is not a universal claim that one organism can never perform both steps.
