Table 6.3 Sum mary of the enzymatic treatment of synthetic dyes.

Enzyme Organism Dye (s) Note Reference

Lignin
peroxidase
(LiP)

Phanerochaete
chrysosporium

Anthraquinone (Poly R-478, Reactive
Blue 19), azo (Acid Orange 52),
diazo (Direct Red 28), triarylmeth-
ane (bromophenol blue), hetero-
cyclic (Basic Blue 9, Basic Blue 17,
Basic Green 5), polymeric (Poly
S-119, Poly T-128)

2 mM of veratryl alcohol added, Direct
Red 28, Poly R-478, and Poly T-128
was decolorized <54%. Isozyme
LiP 3.85 could decolorize certain
dyes (e.g., Acid Orange 52) without
veratryl alcohol

[141]

Anthraquinone (Acid Green 27,
Acid Blue 25), azo (Acid Violet 7,
Acid Orange 74), diazo (Reactive
Black 5), triazo (Acid Black 24),
indigoid (Acid Blue 74), phthalocya-
nine (Reactive Blue 15),

1 mM of veratryl alcohol added, pH
3.5-5, Acid Black 24 was diicult
to decolorize by LiP, MnP was not
efective

[142]

Heterocyclic (Basic Blue 9, azure B) N -Demethylation of Basic Blue 9

yielded azure B and azure A

[143]

Triarylmethane (Basic Violet 9) N -Demethylation observed [22]

Anthraquinone (Reactive Blue 4), azo
(Acid Black 194), diazo (Acid Red
119), Ranocid Fast Blue

2.5 mM of veratryl alcohol added [144]

Anthraquinone (Reactive Blue 4), azo
(Acid Black 194), diazo (Acid Red
119), Ranocid Fast Blue, and several
others

Co-cultivated with P. ostreatus , high
laccase and MnP activity, decoloriza-
tion occurred without H 2 O 2
