| description | This study was performed to investigate the physiochemical effect on the protease adsorption produced by Bacillus sp. using
highly specific ion exchange membrane (IExM). Effects of pH solution (adjusted with HCl and NaOH), ionic strength (adjusted
by NaCl), and initial concentration on adsorption study were performed by using affinity polyethersulfone (PES) membrane
integrated with fish scale hydroxyapatite (FSHAp), FSHAp/PES IExM. At 1.0 M, the maximum adsorption capacity was
recorded by 0.229 mg/cm2 in 90 minutes incubation time. The optimum pH was found to be at pH 8 with adsorption capacity
of 0.211 mg/cm2 in 90 minutes incubation time. The optimum adsorption capacity with 0.204 mg/cm2 was observed when
adsorption study performed with initial concentration at 0.9 mg/ml. Experimental data showed the protease adsorbed higher
in alkaline condition compared to acidic solution. Further experiment showed that increase in ionic strength leads to noticeable
increase in adsorption capacity which is due to aggregation of enzyme molecules in solution. The adsorption study also
showed great adsorption behavior when high initial concentration applied as high number of free enzyme molecule to be
adsorbed. |
