Abstract: (9663 Views) |
| In this study, seasonal variation on the acetylcholinesterase enzyme activity and on the protein in
bivalvia Mytilaster lineatus and crustacean Pontogammarus maeoticus was investigated in 2010-2011 in
Babolsar, in coast of the Caspian Sea. Maximum average of protein amount in Mytilaster lineatus was
(10.461 ± 0.4833 mg/ml) in late winter and the highest average of acetylcholinesterase (AChE) activity
(24.635 ± 0.7829 μmol / min / mg protein) was in the late autumn. Maximum average of protein amount in
Pontogammarus maeoticus was (9.521 ± 0.1482 mg/ml) in late summer and the highest average of AChE
activity (25.155 ± 1.5180 μmol/ min / mg protein) was in the late summer. The result of statistical analysis
using ANOVA, P<0.05 showed significant differences between the levels of acetylcholinesterase enzymes
and Protein found in both organisms in different seasons of the year. This final result indicated that the
minimum stress in bivalvia Mytilaster lineatus was in the cold seasons and in crustacean Pontogammarus
maeoticus was in the warm seasons. |
