Det finns 3 olika sorters Chlorella<\/h2>\n\n\n\n

Chlorella \u00e4r en encellig eukaryot alg som v\u00e4xer i b\u00e5de fototrofa och mixotrofa f\u00f6rh\u00e5llanden, fr\u00e4mst i s\u00f6tvatten. <\/span> Botaniker har beskrivit ett stort antal arter av Chlorella, men endast tre sorter \u00e4r f\u00f6r n\u00e4rvarande erk\u00e4nda (Krienitz et al., 2004) [1] . <\/span><\/p>\n\n\n\n

De tre sorterna av Chlorella som definieras av botaniker \u00e4r : <\/h3>\n\n\n\n

– Chlorella vulgaris
– Chlorella lobophora
– Chlorella sorokiniana<\/strong><\/h4>\n\n\n\n

Det taxonomiska kriteriet f\u00f6r att best\u00e4mma sl\u00e4ktet Chlorella<\/a> fastst\u00e4lldes av Fott et al. 1969 [2]. Chlorella vulgaris \u00e4r f\u00f6r n\u00e4rvarande den mest odlade chlorellasorten, s\u00e4rskilt f\u00f6r produktion av ekologisk chlor<\/a>ella. Denna sort har visat sig vara s\u00e4rskilt l\u00e4mplig f\u00f6r odling i mikroalgodlingar<\/a>. Chlorella vulgaris, som fram till f\u00f6r n\u00e5gra \u00e5r sedan tillh\u00f6rde taxonet Chlorella pyrenoidosa, v\u00e4xer extremt snabbt i b\u00e5de fototrofa och mixotrofa f\u00f6rh\u00e5llanden n\u00e4r den h\u00e5lls i gynnsamma odlingsf\u00f6rh\u00e5llanden.<\/span><\/p>\n\n\n\n

Taxonet Chlorella pyrenoidosa har nu f\u00f6rsvunnit (Kessler 1976, 1992) [3,4].<\/span>enligt klassificeringen av taxa \u00e4r Chlorella klorofyter, s\u00e5 kallade gr\u00f6nalger.<\/span><\/p>\n\n\n\n

Organismer som kallas Chlorellaceae tillh\u00f6r klorofyterna (gr\u00f6nalgerna) i gruppen Trebouxiophyceae. Chlorellaceae delas in i tv\u00e5 besl\u00e4ktade grupper, parachlorella-gruppen och chlorella-gruppen, som omfattar Chlorella vulgaris (Krienitz et al., 2004) [5]. Dessa \u00e4r kocciace\u00f6sa gr\u00f6nalger med sm\u00e5 sf\u00e4riska gr\u00f6na celler, ofta kallade ”gr\u00f6na bollar”. <\/span><\/p>\n\n\n\n

F\u00f6r att skilja en art fr\u00e5n en annan studeras alltid olika egenskaper: t.ex. cellv\u00e4ggens<\/a> ultrastruktur, pyrenoidernas ultrastruktur, cellv\u00e4ggens kemiska sammans\u00e4ttning, serologiska korsreaktioner, fysiologi, biokemi, morfologi och molekyl\u00e4rbiologi. <\/span><\/p>\n\n\n\n

Arten ”Chlorella pyrenoidosa” finns inte!<\/h3>\n\n\n\n

Chlorella pyrenoidosa anses vara en blandning av arter, varav majoriteten \u00e4r vulgaris<\/strong>.<\/span><\/p>\n\n\n\n

Under 1992 unders\u00f6ktes olika algkulturer m\u00e4rkta med ”Chlorella pyrenoidosa”, vilket visade att kulturer m\u00e4rkta med Chlorella pyrenoidosa b\u00f6r klassificeras som olika arter. Det var m\u00f6jligt att identifiera stammar av Chlorella vulgaris som felaktigt hade registrerats under namnet ”Chlorella pyrenoidosa”.<\/span>En stor del av de algkulturer som klassificerats som ”Chlorella pyrenoidosa” tillh\u00f6r i sj\u00e4lva verket arten Chlorella sorokiniana. Chlorella fusca” klassificeras inte l\u00e4ngre i sl\u00e4ktet Chlorella utan i det besl\u00e4ktade sl\u00e4ktet Scenedesmus (Kessler & Huss; 1992) [6]. <\/span><\/p>\n\n\n\n

Slutsats<\/h3>\n\n\n\n

\u00c5r 1999 ingick tre arter och Chlorella kessleri i sl\u00e4ktet Chlorella (Huss et al., 1999) [7].<\/span>I dag ing\u00e5r endast tre arter i Chlorella-gruppen: Chlorella vulgaris, Chlorella lobophora <\/strong>och Chlorella sorokiniana<\/strong> (Krienitz et al., 2004).<\/span><\/p>\n\n\n\n

Klassificeringen och differentieringen av chlorella \u00e4r sv\u00e5r och f\u00f6rblir en fr\u00e5ga f\u00f6r specialister. De flesta av egenskaperna hos dessa arter \u00e4r mycket lika. Detta f\u00f6rsv\u00e5rar naturligtvis identifiering och klassificering, vilket leder till felklassificering och dubblering. Mer \u00e4n 100 Chlorella-arter har beskrivits, och de flesta av dem har beh\u00f6vt revideras.<\/span><\/p>\n\n\n\n

Ingen studie har n\u00e5gonsin publicerats som ger j\u00e4mf\u00f6rande effektresultat mellan olika Chlorella-arter.<\/span><\/strong><\/p><\/blockquote><\/figure>\n\n\n\n
