| dc.description | The study on the toxicity of chitosan diethyl phosphate (ChDP), a controlled release
insecticide, on the activities of butyrylcholinesterase (BuChE) and acetylcholinesterase
(AChE) in rainbow trout exposed to this pesticide was carried out. It was found that
ChDP reduced BuChE activity in O. mykiss by a factor of eight at 6 days, with high
fluctuation to the end of the exposition time at 12 days. The in vitro analysis of brain
AChE treated with ChDP and Phenamiphos showed that it was competitively inhibited
by both organophosphates. The values obtained for Km and Vmax for the AChE-ChDP
(Km: 21.23 μM; Vmax: 43.10 μmol/min/g) and AChE-Phenamiphos (Km: 38.62 μM; Vmax:
38.91 μmol/min/g) systems were relatively low compared to values of the AChE (control)
system (Km: 62.99 μM; Vmax: 63.29 μmol/min/g). Results reported in this study confirmed
that chitosan diethyl phosphate performs similarly to organophosphate pesticides, producing
inhibition in cholinesterases in rainbow trout. | |
