Table 1: Total hydrolysis yields obtained using various substrates treated with free enzymes (C1 or C2) or immobilized cellulases (C1S1, C1S2, C2S1, C2S2). Hydrolysis reactions were conducted in 0.1 M phosphate buffer (pH 5.0) at 50°C for 24 h using a water bath; n = 3; Mean ± Standard Error. For each substrate, values with the same subscript letter are statistically similar while values with different subscript letters are statistically different (p<0.05). For the subscript letters, lower case letters are used for all systems (free or immobilized) incorporating C1, whereas upper case letters are used for C2. PASC: Phosphoric acid swollen cellulose; OA: Office automation. |
