Caracterización de enzimas hidrolíticas de Aspergillus ficuum producidas en fermentación sólida sobre torta de canola

this paper, describes the characterization respect to ph and temperature of semi-purified extracts by ultrafiltration step of the enzymes phytase, cellulase and xylanase produced by aspergillus ficuum dsm 932 strain, in solid state fermentation (ssf) using cold-pressed canola cake as substrate. phytase showed the optimal ph and temperature 6.0 and 60°c, respectively, while cellulase showed a ph optimal of 7.0 with an optimal temperature of 60°c and xylanase extract an optimal ph of 5.4 and an optimal temperature of 45°c.
