Use of Fungal Laccases and Peroxidases for Enzymatic Treatment of Wastewater Containing Synthetic Dyes - Green Chemistry for Dyes Removal from Wastewater - page 243

Sclerotium rolfsii Indigoid (Vat Blue 1) Degradation products identiied, HBT,

acetosyringone, and 4-hydroxy-
benzenesulfonic acid were used as
mediators

[175]

Anthraquinone (Disperse Red 60,
Disperse Blue 19, Acid Blue 225),
azo (Acid Orange 5), diazo (Reactive
Black 5), triazo (Direct Blue 71),
indigoid (Acid Blue 74), triarylmeth-
ane (Acid Violet 17, Basic Violet 3,
Basic Red 9), Reactive Blue 221

Reactive Blue 221 was the most efec-
tively decolorized, Acid Blue 225,
Acid Orange 5, Reactive Black 5
were more resistant, chelating agent
for copper and iron inhibit the lac-
case activity, laccases from six more
fungi ( P. ostreatus , Schizophyllum
commune , Neurospora crassa ,
Polyporus sp., Trametes villosa , and
Myceliophtora thermophila ) were
tested

[153]

Trametes versicolor Anthraquinone (Acid Green 27), azo

(Acid Violet 7), indigoid (Acid
Blue74)

Acid Green 27 was readily decolor-
ized, others required mediator
(low-molecular weight fraction of
culture iltrate or ABTS

[160]

T. hir s ut a Anthraquinone (Reactive Blue 19, Acid

Blue 225), diazo (Reactive Black 5),
triazo (Direct Blue 71), triarylmeth-
ane (Basic Red 9), indigoid (Acid
Blue 74), Reactive Blue 221

Anthraqunone dyes detoxiied, azo
dyes were less so, Reactive Blue
221 was still toxic, immobiliza-
tion improved the stability and less
susceptible to inhibitors, reuse of
treated water was attempted
