Overcentrifugation, i.e., the application of forces in excess of the minimum, causes the cells to adhere to the bottom of the test tube so that vigorous agitation is necessary before they can be resuspended.

ultracentrifugation


Explanation:
I don't think this is a mistake as would suggest centrifugation excessive.
It's a specific procedure.

Surcentrifuger n'existe pas mais excessive veut dire "trop" et n'est pas acceptable étant donnée la définition du texte source.
En fait il s'agit d'une centrifugation allant au dela de la vitesse/durée (ultra pour la vitesse) minimum pour produire un culot. Mais elle est bien volontaire selon le texte source. Elle n'est pas excessive car elle n'a pas de conséquences négatives.

centrifugation plus poussée


Explanation:
l'ultracentrifugation est utilisée afin de séparer les constituants cellulaires les uns des autres (les cellules ne sont plus intactes suite à cette procédure):
"C'est en 1929 que Theodor Svedberg à l'idée de soumettre le matériel cellulaire à une centrifugation poussée (ultracentrifugation) afin d'isoler les ..." www.ilemaths.net/encyclopedie/Biochimie.html

Dans le cas présent les cellules sont récupérées après centrifugation et remises en suspension, donc sont intactes, donc il ne s'agit pas d'ultracentrifugation.

Example sentence(s):
  • une centrifugation légèrement plus poussée est nécessaire. Au pire, la correction n'a. jamais dépassé 0010, valeur en densité optique. ...

centrifugation excessive


Explanation:
NOT ultracentrifugation because ultra just means highspeed and here it is more than the centrifugation recommanded...therefoer it is centrifugation excessive.
