“…Taking into account protein concentration methods, salting out [10,12,14,[23][24][25] and dead-end ultrafiltration (UF) [10, 12-14, 17-21, 24] are used predominantly, whereas evaporation [16], acetone precipitation [13] and lyophilisation [12,20] are not common procedures. Chromatography (ion exchange [10][11][12][13][14][17][18][19][20][21][22][23][24][25], affinity [16,17,22,23] and hydrophobic interaction [15]) seems to be an obvious technique of laccase separation. In the next group of separation processes, aimed at removing undesired small molecules, there is dialysis [10,12,14,15,17,20,[23][24][25], gel filtration [11-13, 16, 18, 20, 22, 25] and diafiltration [14,19,21,24].…”
