The morphological
optimization of
Trichoderma harzianum was carried out using several
surfactants to achieve increased
cellulase production. Addition of the
surfactants to the
culture medium successfully modified the fungal morphology from an aggregated form to a dispersed form.
Optimization of the fungal morphology increased
cellulase activity up to 177%. The morphologically optimized conditions enhanced the accessibility of the
fungus to
substrates and thus promoted
cellulase production.
