Effect of surfactants on cellulase production by Nectria catalinensis

The effect of different nonionic surfactants (Tween 80, Tween 20, Triton X-100) and polyethylene glycol (PEG 6000) was tested on cellulolytic enzyme system production. Tween 80 gave the highest yield of endoglucanase, exoglucanase, and cellobiase at the 20th day of growth, presumably by causing incr...

Tween 80 gave the highest yield of endoglucanase, exoglucanase, and cellobiase at the 20th day of growth, presumably by causing increased permeability of cell membranes and/or by promoting the release of cell-bound enzymes. Maximal yield of endoglucanase was achieved with 1.7 mM Tween 80, whereas exoglucanase and cellobiase were at 0.85 mM. In the same way, this compound increased fungal growth.

High yields of endoglucanase and exoglucanase were achieved with PEG 6000 in comparison with the control, presumably by increasing enzyme stability. 1996 https://bibliotecadigital.exactas.uba.ar/collection/paper/document/paper_03438651_v33_n4_p275_Pardo http://hdl.handle.net/20.500.12110/paper_03438651_v33_n4_p275_Pardo
