RESUMO
The strain of Cunninghamella echinulata 9980 was first selected with high aminoacylase activity . In three submerged cultures, the aminoacylase activity in the mycelial cell was compared . A number of factors have effects on the resolution reaction. The results showed that, peptone culture gave the highest aminoacylase activity with 680U/g.The optium temperature,pH,and substrate concentration were 55℃, 7.0,and 0.2mol/L,respectively. The ions in the buffer lowered the activity,but the Co~(2+) in 10~(-4)~10~(-3 )mol/L was necessary for its activity.
