Bioaccumulation of trace elements in pelagic fish from the Western Indian Ocean ArchiMer
Kojadinovic, Jessica; Potier, Michel; Le Corre, Matthieu; Cosson, Richard P.; Bustamante, Paco.
Trace elements were analyzed in fish of commercial interest to determine their importance in marine systems of the Western Indian Ocean and their bioaccumulation patterns. The results are equivalent or lower than levels reported in ichthyofauna worldwide. Certain values of muscular Cd, Hg, Pb and Zn were, however, above thresholds for human consumption. Levels varied among tissues, species and fish length, but were seldom influenced by the nutritional condition of the fish, its gender and its reproductive status. Correlations between hepatic Hg and Se levels in Swordfish (r(2) = 0.747) and Yellowfin Tunas (r(2) = 0.226), and among metallothionein linking metals imply the existence of detoxification processes in these species. Level differences between fish...

Copper in plants Braz. J. Plant Physiol.
Yruela,Inmaculada.
Copper is an essential metal for normal plant growth and development, although it is also potentially toxic. Copper participates in numerous physiological processes and is an essential cofactor for many metalloproteins, however, problems arise when excess copper is present in cells. Excess copper inhibits plant growth and impairs important cellular processes (i.e., photosynthetic electron transport). Since copper is both an essential cofactor and a toxic element, involving a complex network of metal trafficking pathways, different strategies have evolved in plants to appropriately regulate its homeostasis as a function of the environmental copper level. Such strategies must prevent accumulation of the metal in the freely reactive form (metal detoxification...

De novo transcriptome assembly of the lobster cockroach Nauphoeta cinerea (Blaberidae) Genet. Mol. Biol.
Segatto,Ana Lúcia Anversa; Diesel,José Francisco; Loreto,Elgion Lucio Silva; da Rocha,João Batista Teixeira.
Abstract The use of Drosophila as a scientific model is well established, but the use of cockroaches as experimental organisms has been increasing, mainly in toxicology research. Nauphoeta cinerea is one of the species that has been studied, and among its advantages is its easy laboratory maintenance. However, a limited amount of genetic data about N. cinerea is available, impeding gene identification and expression analyses, genetic manipulation, and a deeper understanding of its functional biology. Here we describe the N. cinerea fat body and head transcriptome, in order to provide a database of genetic sequences to better understand the metabolic role of these tissues, and describe detoxification and stress response genes. After removing low-quality...

Bergsten-Torralba,L.R.; Nishikawa,M.M.; Baptista,D.F.; Magalhães,D.P.; Silva,M. da.
The objective of this study was to investigate the capacity of decolorization and detoxification of the textile dyes Reactive Red 198 (RR198), Reactive Blue 214 (RB214), Reactive Blue 21 (RB21) and the mixture of the three dyes (MXD) by Penicillium simplicissimum INCQS 40211. The dye RB21, a phthalocyanine, was totally decolorized in 2 days, and the others, the monoazo RR198, the diazo RB214 and MXD were decolorized after 7 days by P. simplicissimum. Initially the dye decolorization involved dye adsorption by the biomass followed by degradation. The acute toxicity after fungal treatment was monitored with the microcrustacean Daphnia pulex and measured through Effective Concentration 50% (EC50). P. simplicissimum reduced efficiently the toxicity of RB21...

Detoxification enhancement in the gymnodimine-contaminated grooved carpet shell, Ruditapes decussatus (Linne) ArchiMer
Medhioub, Walid; Gueguen, Marielle; Lassus, Patrick; Bardouil, Michele; Truquet, Philippe; Sibat, Manoella; Nejib, Medhioub; Philippe, Soudant; Mejdeddine, Kraiem; Amzil, Zouher.
In the Gulf of Gabes (Tunisia, Eastern Mediterranean sea), the grooved carpet shell Ruditapes decussatus has been seen to contain persistent levels of gymnodimine (GYM) for several years. The present experimental work represents the first attempt to assess detoxification kinetics of fast-acting toxins (FAT) in marine molluscs fed specific diets of non-toxic algae (Isochrysis galbana). To find an optimal detoxification method, two experiments were performed in which clams were first fed the toxic dinoflagellate Karenia selliformis to artificially contaminate them with GYM, thus simulating the effect of natural toxic episodes. As a second step, the same clams were fed a non-toxic algae, I. galbana. to speed up the detoxification process. Changes in toxin...

Detoxification of Pacific oyster Crassostrea gigas fed on diets of Skeletonema costatum with and without silt, following PSP contamination by Alexandrium minutum ArchiMer
Gueguen, Marielle; Bardouil, Michele; Baron, Regis; Lassus, Patrick; Truquet, Philippe; Massardier, Julie; Amzil, Zouher.
Contamination of shellfish by paralytic shellfish poisoning ( PSP) toxins poses an economic threat to shellfish farmers. As contaminated shellfish cannot be harvested for long periods of time, it would be very useful to develop processes to optimise and shorten their detoxification. In this study, Pacific oysters Crassostrea gigas were first experimentally contaminated over a period of 13 days with a continuous flow of toxic Alexandrium minutum cultures at concentrations ranging from 150 to 200 cell ml(-1) ( toxin content after 13 days of contamination 438 mu g STX equiv. 100 g(-1) wet weight). Then, two different detoxification treatments were tested and showed detoxification rates greater than those observed in coastal environments. The first treatment...

Abstract: By-products of industrial processes nutritionally rich as castor meal have been used as an energy source in feed for goats in order to increase the lipid characteristics of milk and dairy products. The present study was conducted to evaluate the physicochemical, microbiological and sensory properties of goat cheese "Coalho Type" made from milk of goats submitted to diets with increasing levels (33, 67 and 100%) of detoxified castor meal, replacing soybean meal. The cheeses produced showed no changes in sensory attributes (P>0.05). However, the diet with different levels of detoxified castor meal promoted an increase in the levels of unsaturated fatty acids in milk and cheese, especially the C6:0; C10:0; C14:0; C16:0; C18:1 and C18:3 profile,...

Effect of caffeine and tannins on cultivation and fructification of Pleurotus on coffee husks BJM
Fan,Leifa; Soccol,Andréa Thomaz; Pandey,Ashok; Vandenberghe,Luciana Porto de Souza; Soccol,Carlos Ricardo.
The objective of this work was to study the effect of caffeine and tannins on Pleurotus sp. cultivation and to evaluate the feasibility of using coffee husks as substrate for mushroom cultivation. Eight strains of P. ostreatus and two strains of P. sajor-caju were screened on a medium prepared from agar extract of coffee husk. Based on best mycelial growth and biomass production, the strain P. ostreatus LPB 09 was selected for detailed studies. With the increase of caffeine concentration, the mycelial growth and the biomass production decreased, and no growth was observed when concentration of caffeine was 2500 mg/L. Furthermore, Pleurotus did not degrade the caffeine, but absorbed it. Tannin under 100 mg/L in the medium stimulated the growth of mycelia,...

Etude de l’impact de l’alimentation sur la detoxification de la palourde <Ruditapes decussatus> contaminée in-situ par les gymnodimines (lagune de Boughrara, sud de la Tunisie) OceanDocs
Medhioub, W.; Amzil, Z.; Sudant, Ph.; Hamza, A.; Medhioub, M.N.; Kraiem, M.M.; Lassus, P..
Depuis 1994 la prolifération de la micro algue toxique, Karenia selliformis, productrice de la gymnodimine (GYM), dans le golfe de Gabes (Sud de la Tunisie) contamine fréquemment les sites de production de la palourde Ruditapes decussatus et, d’une façon continue la lagune de Boughrara, entrainant ainsi l’arrêt de la commercialisation de cette espèce. La contamination des mollusques bivalves par les phycotoxines est un problème mondial qui nécessite d’apporter une solution. C’est dans ce cadre que s’inscrit ce travail qui a pour objectif l’étude de l’impact de l’alimentation à base de la microalgue fourrage Isochrysis galbana Tahitian clone (T.Iso) sur la cinétique de détoxification de la palourde contaminée naturellement. Les analyses de la toxine ont été...

Farelo de mamona destoxificado na dieta de cabras leiteiras. Repositório Alice
FERNANDES, M. F..
Resumo: Além das questões ambientais e econômicas, a produção de biocombustíveis desperta interesse pela possibilidade de geração de alimentos alternativos para a nutrição animal. A mamona, como uma dessas fontes, gera subprodutos que, pela sua toxicidade, não podem ser utilizados na ração animal sem prévia destoxificação. Objetivou-se com esse estudo destoxificar o farelo de mamona e avaliar a sua utilização na alimentação animal. O hidróxido de sódio (NaOH) foi utilizado para destoxificar o farelo de mamona. A hidrólise da ricina foi obtida quando se utilizou a proporção mínima de 1:34:84 (p/p) de NaOH:farelo:água, referente ao tratamento com 30 g de NaOH e 2500 mL de água. A confirmação da destoxificação foi realizada através da SDS-PAGE utilizando...
