PRIGIONI, Gaston Ariel; RODRIGUEZ, Maria Daniela; ZAPATA, Pedro Darío  and  VILLALBA, Laura Lidia. Corn liquor as a culture medium for laccase production by Phlebia brevispora. Rev. cienc. tecnol. [online]. 2018, n.30, pp.1-12. ISSN 1851-7587.

The objective of this work was to test different culture media in order to achieve high laccase production by Phlebia brevispora using low cost substrates. With a medium composed of malt extract, corn liquor and CuSO₄, 3.807 U/L of laccase at day 14 of incubation were obtained. Laccase production was tested with two different soluble corn extracts, analytical and industrial grade, but no statistical significant differences in laccase production were detected when using corn liquor of industrial (3,761U/L), or analytical grade (3,726U/L), both values attained at day 10 of incubation. Thus, an inexpensive medium for laccase production could be selected, also replicable in a 5 L bioreactor.
