Different time intervals are selected to examine the effect of contact time at an optimum pH
value of each metal ion .
The crude enzyme extract was prepared from overnight grown bacterial cultures at their optimum pH
The activity was recorded and the data was utilized to find out the optimum pH
This result is parallel to the findings by Syafawati  and Fan  who reported that the initial pH 7 represented the optimum pH
for biohydrogen production.
Using caster lipase Altaf, (1997) observed an optimum pH
of 6 with phosphate buffer.
Characterization of crude laccase enzyme The optimum pH
determination and pH stability studies of the crude laccase
Eucerin pH5 Skin-Protection line, for example, features products formulated to help to restore and retain the optimum pH
for healthy skin and stabilize the hydrolipid film that protects the outer layer of skin.
for Dosidicus gigas trypsin activity was 8.
The operational stability of the immobilized lipase was assayed by using immobilized lipase (100 mg) in successive batches carried out under hydrolysis reaction conditions at 37[degrees]C and the optimum pH
Different aliquots of the crude containing laccase were submitted to activity estimation using different pH and temperature conditions to determine the optimum pH
and temperature of enzyme activity.
In order to determine the effect of optimum pH
, 250 mL of MRS broth was prepared in a 500 mL conical flask.
The optimum pH
range for growth of this species is 6.
