Purification and properties of alanine racemase from crayfish Procambarus clarkii
Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2000Fresh water crayfish Procambarus clarkii is known to accumulate D-alanine remarkably in muscle after seawater acclimation, accompanied by an increase in alanine racemase activity. We have purified alanine racemase from crayfish muscle to homogeneity. The enzyme is a monomeric protein with a molecular mass of 58 kDa. It is highly specific to alanine and

Eleven polymorphic microsatellites isolated from red swamp crayfish, Procambarus clarkii
Molecular Ecology Resources, 2008AbstractEleven microsatellites were isolated from a genomic DNA library enriched for CA‐ and GA‐repeats, and were characterized in 48 individuals of red swamp crayfish Procambarus clarkii. All 11 microsatellites were polymorphic with an average of allele number of 6.6 per locus.

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 ...
