Aminopeptidase activity from the hepatopancreas of Procambarus clarkii
Biochemical Systematics and Ecology, 1992This study examined aminopeptidase in the digestive gland of the freshwater crayfish, Procambarus clarkii. The enzyme has a molecular weight of 74,000 and consists of two subunits of 28,000 and 46,000 Mr. The enzymatic activity is maximal at pH 8.6 and at 55°C and follows the Michaelis-Menten kinetics.

Bioaccumulo di inquinanti in Procambarus clarkii
2012Procambarus clarkii può accumulare efficacemente nel proprio organismo metalli pesanti e tossine algali. Per questa ragione la sua cattura a fini alimentari deve avvenire solo in acque di buona qualità. Le fitotossine si possono trovare in concentrazioni maggiori nella ghiandola digestiva (epatopancreas), che ha sede nel cefalotorace (porzione ...

Crustacea (Procambarus clarkii) response to an organophosphate diet
Environmental Pollution Series A, Ecological and Biological, 1985Abstract Large quantities of the organophosphate Guthion®, used to control insect infestations on large Louisiana plantations, can potentially enter surrounding wetland habitats and impact commercially important crayfish populations. The adsorption of Guthion to plant oils and organic sediments means that its impact on crayfish will include, and ...

Copper Bioaccumulation and Depuration by Red Swamp Crayfish, Procambarus clarkii
Bulletin of Environmental Contamination and Toxicology, 1998Environmental contamination of copper occurs from two major sources: weathering and land-drainage. Mine production of Cu was estimated to be 307 million metric tons sometime ago (Nriagu et al 1979). A considerable amount of copper is contributed by the effluents of metal finishing industries to sewage sludge.

Bioaccumulo di inquinanti in Procambarus clarkii
2013Procambarus clarkii può accumulare efficacemente nel proprio organismo metalli pesanti e tossine algali. Per questa ragione la sua cattura a fini alimentari deve essere attentamente controllata e regolamentata. Le fitotossine in particolare si possono trovare in concentrazioni maggiori nella ghiandola digestiva (epatopancreas), che ha sede nel ...

Phosphorylation in crayfish (Procambarus clarkii) eggs during hatching
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1993Abstract 1. 1.|The high-energy phosphorylation metabolism in crayfish, Procambarus clarkii eggs during brooding and juvenile crayfish after hatching was studied by in vivo31P nuclear magnetic resonance (31P NMR) spectroscopy. 2. 2.|Inorganic phosphoric acid (Pi) and adenosine-5′-triphosphate ATP(γ-,α-,β-) were detected in the dark brownish ...
