Enzyme Organism Dye (s) Note Reference

Triarylmethane (bromocresol green,
bromocresol purple, bromophenol
blue, bromophenol red, m -cresol
purple, o -cresol red, phenol red)

Manganese-independent peroxidase
(versatile peroxidase) prefer
brominated dyes (e.g., phenol red)

[150]

Schizophyllum sp. Azo (Acid Orange 5, Acid Orange 10),

diazo (Direct Red 28),

30% decolorization of 1 mM Acid
Orange 5 in 60 min with 20 U/L of
puriied MnP

[147]

Laccase Aspergillus niger

(genetically
modiied)

Anthraquinone (Reactive Blue 19) Violuric acid and HBT accelerated the

decolorization, surfactants showed
inhibitory efect

[169,170]

Custom-synthesized diazo dyes Water insoluble dyes (without sulfonate

group) could not be decolorized.
HBT used

[172]

Cerrena unicolor Anthraquinone (Acid Blue 40, Acid

Blue 62), azo (Reactive Blue 81,
Acid Red 27), poly-azo (Reactive
Black 22)

Enzyme kinetics studied, Acid Blue 40
was the most preferred substrate, no
redox mediators used

[173]

Ganoderma
lucidum

Anthraquinone (Acid Black 5), diazo
(Acid Blue 19)

Crude enzyme more thermostable,
77% and 92% of Acid Black 5 and
Acid Blue 19 decolorized in two
hours ([dye] 0 = 50 mg/L, laccase
dose = 25 U/mL), HBT used
