Abstract
Trametes versicolor is a white-rot fungi which is able to produce laccase and the BIOTECH strain of this organism was used in this study. The main objective of the study was to determine the production of laccase by the test organism in four different media: corn cobs broth, rice bran broth, cassava starch broth and potato dextrose broth at various incubation periods and in varying initial pHs. The volumetric activity (U/mL) of the laccase produced was determined using syringaldazine assay. F-test and Duncan?s Multiple Range Test were used in the statistical analysis to determine the significant differences among treatments and to determine the conditions for production of laccase with the highest volumetric activity. Based on the results, of the media tested, corn cobs gave the highest value. A 7- day incubation period and an initial pH of 5.5 of the medium also showed significantly higher enzyme yield and activity.
