Abstract
Procédé de préparation de suspensions aqueuses ou de boues de microfibrilles cellulosiques obtenues à partir de la fermentation bactérienne, dans lequel lesdites microfibrilles cellulosiques sont libérées du milieu de culture utilisé pour ladite fermentation bactérienne par lavage. Ensuite on triture puis on fait macérer les microfibrilles à l'aide de moyens mécaniques. Si l'on veut on draine le produit obtenu sous forme de suspension aqueuse afin de former une boue aqueuse.
