Title: Violacein Biotransformation By Basidiomycetes And Bacteria.
Author: Bromberg, N
Durán, N
Abstract: The biotransformation study of the pigment (violacein) produced by Chromobacterium violaceum, was verified by its decolorization utilizing six different organisms in liquid and solid media. Lentinus edodes showed the fastest violacein decolorization (8th d) in solid medium whereas in a liquid medium, violacein was rapidly decolorized in 2 h by Azotobacter vinelandii. Adsorption experiments indicated no significant contribution for the decolorization process for all organisms in both media. The results showed poor lignin peroxidase activity in both media but manganese peroxidase and laccase activity varied according to the organism used. Siderophores presence was also detected in all organisms mainly in the liquid medium experiment.
