Enzyme Organism Dye (s) Note Reference

Mixtures of anthraquinone (Acid
Blue 62), azo (Reactive Red 195,
Reactive Yellow 145, Acid Yello
49, Acid Red 266), diazo (Reactive
Blue 222, Reactive Black 5), triazo
(Direct Blue 71) poly-azo (Direct
Red 80), and Direct Yellow 106

Up to 35% decolorization of acid dye
model wastewater in 24 h, Acid
Yellow 49 was more resistant, Acid
Blue 62 was a good substrate, Acid
Red 266 was more resistant, reactive
dye and direct dye model wastewa-
ters could not be decolorized, toxic-
ity reduction was less with enzyme
alone

[157]

P. sajor-caju Azo (Acid Red 18), diazo (Acid

Black 1), triazo (Direct Blue 71)

40 μM of all dyes completely decolor-
ized in 24 with 16 U/mL of laccase,
no redox mediators used

[158]

Diazo (Reactive Black 5) HBT improved the decolorization [159]

Polyporus sp. Anthraquinone (Reactive Blue 19) Two degradation products detected [174]

Pycnoporus
sanguineus

Anthraquinone (Reactive Blue 19) Rapid decolorization (90% within 10

min) without redox mediator

[168]

Pyricularia oryzae Custom synthesized seven mono-azo

derivatives

Dimethyl derivatives were the best
