Immobilization of a Pleurotus ostreatus Laccase Mixture on Perlite and Its Application to Dye Decolourisation

Table 2

Adsorption capacity of treated perlite samples obtained in different experimental conditions. Data are average values of three independent experiments. The standard deviation of each series of results was less than ±10%.

Perlite sample	APTS (%)	Glutaraldehyde activation	Adsorption capacity; (mg RBBR/g solid)	Immobilization yield (%)
A1	4	0.5% (pH 6.5)	71	45
A2	4	—	96	—
A3	0.4	0.5% (pH 6.5)	28	29
A4	4	0.5% (pH 6.5, 2X)	64	—
A5	0.4	0.5% (pH 8)	31	16
A6	4	0.5% (pH 8)	64	38
A7	0.4	1% (pH 8 60°C)	33	51
