Trin ex Steudel) rhizome was studied at Lake Ferto/Neusiedler See using the litter bag technique. Samples were analysed for rhizome dry mass, fibre (cellulose, hemicellulose, lignin) and nutrient content (C, N, P and S), litter-associated fungal biomass, potential microbial respiration (electron transport activity: ETS) and cellulolitic bacteria. The mass loss of decomposing rhizome was rapid in the initial period and only 13.6% of the dry mass remained at the end of the experiment during 953 days. Substantial quantities of C, N, S and P were lost during 99 days; only 18% C, 19% N, 14% S and 6.4% of the P remained after 953 days. Hemicellulose degraded more rapidly than the other fibres whilst the lignin had the slowest rate of decomposition. Bacteria were found to be the primary colonizers of plant detritus, which was followed by fungal growth. An antagonistic relationship was observed between bacteria and fungi. Fungal biomass as determined by ergosterol concentrations ranged between 4.1 and 420 µg g<sup>-1</sup> and peaked every year in September. The number of cellulolitic bacteria varied from 0 to 22 MPN g<sup>-1 </sup> with higher values in summer. The ETS-activity ranged between 0.1 and 1.6 mg O2 g<sup>-1 </sup>h<sup>-1</sup>. The changes in ETS-activity varied almost in parallel with the in situ temperature of the lake water.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Decomposition of <i>Phragmites australis</i> rhizome in a shallow lake","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-05-18 01:31:59.714162","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"phragmites australis rhizome; decomposition; nutrient; fibre;ergosterol; ETS-activity","OtherDescriptors":null,"Notes":null,"AnaPub":2006,"MonPub":null,"DateUpdate":"2020-10-22","DateCreate":"2007-08-02","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000241426900005","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.aquabot.2006.06.005"},"refs":null,"anarec":{"AnaID":112115,"PubliDate":2006,"Pagination":"309-316","XtraPublOfAnaID":null,"ISBN":null,"Volume":"85","Issue":"4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42195,"SerRR":"Aquatic Botany.
