Effect of carbon source
To choose a suitable carbon source for 5’-phosphodiesterase
production, seven carbon sources including glucose,
glycerol, mannitol, dextrine, maltose, sucrose and
starch were investigated at fractions of 3 and 6 % in the
basal medium. As shown in Table 3, among the carbon
sources evaluated, the highest enzyme activity was 213
and 221 U/mL at glucose and sucrose fractions of 6 %,
respectively.
