In this paper the biodegradability of <i>Phaeocystis</i> colony-derived material is analysed with respect to current knowledge and novel data on the chemical nature of <i>Phaeocystis</i> material in relationship with specific bacterial enzymatic activities. Particular emphasis is given to the chemical nature of <i>Phaeocystis</i> colony matrix which constitutes more than 80% of total colony biomass at maximum development. This analysis gives evidence of the potential biodegradability of this mucilaginous material made of nutrient-deprived polysaccharides. Other factors controlling microbial degradation as the production of antibacterial substances by <i>Phaeocystis</i> colonies, cold temperature and lack of inorganic nitrogen and phosphate are further considered. It is concluded that nutrient limitation currently observed at the senescent stage of <i>Phaeocystis</i> blooms might well explain the low biodegradability of <i>Phaeocystis</i> material. However the lack of bacteria attached to colonies during the exponential phase of <i>Phaeocystis</i> bloom development are not clearly understood and needs further investigations.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Microbial degradation of <i>Phaeocystis</i> material in the water column","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-10 01:31:24.175787","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1994,"MonPub":null,"DateUpdate":"2023-06-26","DateCreate":"2003-06-13","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1994NJ88300005","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/0924-7963(94)90016-7"},"refs":null,"anarec":{"AnaID":35581,"PubliDate":1994,"Pagination":"55-65","XtraPublOfAnaID":null,"ISBN":null,"Volume":"5","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43079,"SerRR":"Journal of Marine Systems.
