COSTA, Marcia; TORRES, Marcelo  and  REYES, Alejandro. Characterization of Aspergillus ficuum hydrolytic enzymes produced in solid state fermentation of cold-pressed canola cake. Rev. colomb. biotecnol [online]. 2012, vol.14, n.1, pp.208-215. ISSN 0123-3475.

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.

Keywords : Passiflora; competition; mycoparasitism; inhibition; antagonism.
