Abstract (en)
[origin: JP2017074039A] PROBLEM TO BE SOLVED: To provide methods for fractionating lipids contained in microalgal biomass neither drying the biomass nor using solvents, to obtain compositions whose various ingredients are easily separated afterward.SOLUTION: The invention relates to a method for treating a microalgal biomass, comprising the following steps: providing a microalgal biomass containing at least 15 mass% of lipids relative to the total weight of the biomass and having a dry matter concentration of between 1 g/L and 200 g/L, milling the biomass by a bead mill under the following conditions: the diameter of the beads (d) ranges from 0.2 to 2.5×10m, preferably from 0.4 to 1.0×10m, preferably approximately 0.6×10m, the blade-tip agitation speed (ν) ranges from 4 to 50 m/s, preferably from 5 to 20 m/s, more preferably approximately 8 m/s; and recovering thus obtained composition.SELECTED DRAWING: None
Abstract (fr)
La présente invention un procédé de traitement d'une biomasse micro-algale caractérisé en ce qu'il comprend les étapes suivantes : - disposer d'une biomasse micro-algale comprenant au moins 15 %, en poids de lipides par rapport à la masse totale de ladite biomasse et présentant une concentration en matière sèche comprise entre 1 g/l et 200 g/l, - broyer ladite biomasse au moyen d'un broyeur à billes mis en oeuvre dans les conditions suivantes : - le diamètre moyen des billes (d GM ) varie de 0,2 à 2,5.10 -3 m, de préférence de 0,4 à 1,0 10 -3 m et de manière préférée est d'environ 0,6 10 -3 m, - la vitesse d'agitation en bout de pale (u) varie de 4 à 50 m.s -1 , de préférence de 5 à 20 m.s -1 et de manière préférée est d'environ 8 m.sec -1 ; - le taux de remplissage en billes du broyeur varie de 50 % à 80 % volume/volume, - récupérer la composition obtenue.
