In stagnant nonaerated cultures a phosphate-optimum exists for the nitrogenfixation of 90 µg P/ml. Using fructose-1,6-diphosphate the same quantity of nitrogen is fixed with only 50 µg P/ml. In aerated cultures the differences between inorganic phosphate and fructose-1,6-diphosphate (regarding their influence on the nitrogen-fixation) disappear. The quotient: used up C/fixed N also depends on aeration. In stagnant cultures containing organic phosphate-compounds, the C/N-quotient is lower than in those containing inorganic phosphate. In aerated cultures, however, the C/N-quotient is lowest with orthophosphate. The experiments indicate that the phosphate-esters are incorporated into the cell immediately without splitting up on the cell surface. These incorporated phosphateesters in non-aerated cultures, lacking an extensive oxidative phosphorylation, are apparently important for the economy of nitrogen fixation. The ecological role of the incorporation of phosphate-esters is discussed in relation to the fact that a great part of phosphorus in the natural environment is not inorganic but organic phosphate.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Biochemisch-oekologische Studien zum Phosphathaushalt von Azotobacter chroococcum","OrigTitleLangCode":"de","OrigTitleLangCodeExtended":"ger","OrigTitleLangID":13,"DateLastModified":{"date":"2026-04-23 01:32:14.566330","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1967,"MonPub":null,"DateUpdate":"2021-02-23","DateCreate":"2012-05-16","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A19679802400036","VABBcode":null,"OpenAcc":0,"DOI":"10.1007/BF01618624"},"refs":null,"anarec":{"AnaID":215490,"PubliDate":1967,"Pagination":"202-209","XtraPublOfAnaID":null,"ISBN":null,"Volume":"15","Issue":"1-4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":64660,"SerRR":"Helgoländer Wissenschaftliche Meeresuntersuchungen.
