Fiche technique \u2014 Physarum polycephalum<\/em><\/h2>\n

Nom scientifique :<\/strong> Physarum polycephalum<\/em>
\nNom commun :<\/strong> Myxomyc\u00e8te, blob, \u00ab slime mold \u00bb (en anglais)
\nGroupe :<\/strong> Protiste (Amoebozoa)
\nFamille :<\/strong> Physaraceae
\nType :<\/strong> Organisme unicellulaire plurinucl\u00e9\u00e9 (plasmodium)
\nCouleur :<\/strong> Jaune vif \u00e0 jaune orang\u00e9 durant la phase active

Description<\/h3>\n

Physarum polycephalum<\/em> est un fascinant myxomyc\u00e8te, commun\u00e9ment appel\u00e9 \u00ab slime mold \u00bb<\/strong>. Malgr\u00e9 son apparence proche des champignons, il n\u2019appartient pas au r\u00e8gne des Fungi, mais aux amibozoaires. Durant sa phase active, il forme un plasmodium, une masse vivante g\u00e9latineuse capable de se d\u00e9placer lentement \u00e0 la recherche de nourriture.<\/p>\n

Cet organisme est largement \u00e9tudi\u00e9 pour ses capacit\u00e9s \u00e9tonnantes \u00e0 r\u00e9soudre des labyrinthes, optimiser des trajets et montrer des comportements proches de la prise de d\u00e9cision, ce qui en fait un excellent outil p\u00e9dagogique pour l\u2019\u00e9tude de la biologie et de l\u2019\u00e9cologie.<\/p>\n

Caract\u00e9ristiques principales<\/h3>\n
    \n
  • Organisme vivant \u00e0 fort int\u00e9r\u00eat \u00e9ducatif et scientifique<\/li>\n
  • Formation de r\u00e9seaux ramifi\u00e9s sur substrats humides<\/li>\n
  • Se nourrit de bact\u00e9ries, levures et mati\u00e8re organique en d\u00e9composition<\/li>\n
  • Permet l\u2019observation de processus biologiques en temps r\u00e9el<\/li>\n
  • Non toxique pour les animaux de terrarium, arthropodes et plantes<\/li>\n
  • Id\u00e9al pour projets \u00e9ducatifs et terrariums bioactifs<\/li>\n<\/ul>\n

    Conditions de maintenance<\/h3>\n

    Humidit\u00e9 :<\/strong> \u00c9lev\u00e9e
    \nTemp\u00e9rature :<\/strong> 18\u201326 \u00b0C
    \nLumi\u00e8re :<\/strong> Faible luminosit\u00e9 ou lumi\u00e8re indirecte
    \nSubstrat :<\/strong> Bois en d\u00e9composition, mousses, feuilles mortes ou milieux riches en mati\u00e8re organique humide<\/p>\n

    Alimentation<\/h3>\n

    En culture, il peut \u00eatre nourri avec :<\/p>\n

      \n
    • Flocons d\u2019avoine<\/li>\n
    • Levure<\/li>\n
    • Micro-organismes pr\u00e9sents dans la mati\u00e8re organique<\/li>\n
    • D\u00e9bris v\u00e9g\u00e9taux en d\u00e9composition<\/li>\n<\/ul>\n

      Utilisation \u00e9ducative et comme aliment vivant pour collemboles<\/h3>\n

      Physarum polycephalum<\/em> est \u00e9galement un outil p\u00e9dagogique exceptionnel, permettant d\u2019observer la croissance cellulaire, l\u2019exploration de l\u2019environnement et les comportements adaptatifs en temps r\u00e9el. Il est largement utilis\u00e9 dans les projets \u00e9ducatifs et les exp\u00e9riences de biologie.<\/p>\n

      Dans les terrariums bioactifs, il peut aussi servir de ressource naturelle compl\u00e9mentaire pour l\u2019alimentation de certains collemboles<\/strong>, en favorisant la pr\u00e9sence de micro-organismes et de mati\u00e8re organique autour de son d\u00e9veloppement. Il contribue ainsi \u00e0 un \u00e9cosyst\u00e8me plus riche et \u00e9quilibr\u00e9.<\/p>\n

      Un organisme vivant unique qui combine science, \u00e9ducation et dynamique \u00e9cologique.<\/p>\n
