    Integration of a Recombinant Chitinase into Bacillus thuringiensis Parasporal Insecticidal Crystal 

    Driss, Fatma; Rouis, Souad; Azzouz, Hichem; Tounsi, Slim; Zouari, Nabil; Jaoua, Samir... more authors ... less authors ( Springer-Verlag , 2011 , Article)
    Chitinases have been successfully used in combination with Bacillus thuringiensis delta-endotoxins forming crystals in order to enhance their insecticidal activities. In this context, we opted for promoting the chitinase ...

    Overproduction of Delta-Endotoxins by Sporeless Bacillusthuringiensis Mutants Obtained by Nitrous Acid Mutagenesis 

    Ben Khedher, Saoussen; Zouari, Nabil; Messaddeq, Nadia; Schultz, Patrick; Jaoua, Samir ( Springer-Verlag , 2011 , Article)
    Asporogenic and oligosporogenic Bacillus thuringiensis mutants having the ability to overproduce insecticidal crystal protein were generated by using nitrous acid (50 mg/ml), as chemical mutagenic agent. Insecticidal crystal ...

    Study of the Bacillus thuringiensis Vip3Aa16 histopathological effects and determination of its putative binding proteins in the midgut of Spodoptera littoralis 

    Abdelkefi-Mesrati, Lobna; Boukedi, Hanen; Dammak-Karray, Mariam; Sellami-Boudawara, Tahya; Jaoua, Samir; Tounsi, Slim... more authors ... less authors ( Elsevier Inc. , 2011 , Article)
    The bacterium Bacillus thuringiensis produces, at the vegetative stage of its growth, Vip3A proteins with activity against a broad spectrum of lepidopteran insects. The Egyptian cotton leaf worm (Spodoptera littoralis) is ...

    Improvement of Bioinsecticides Production by Sporeless Bacillus thuringiensis strains in Response to Various Stresses in Low Cost Medium 

    Ben Khedher, Saoussen; Jaoua, Samir; Zouari, Nabil ( Springer-Verlag , 2011 , Article)
    The use of bioinsecticides, particularly those produced by sporeless Bacillus thuringiensis strains, has been shown to be a good alternative in pest management. Two types of sporeless mutants were distinguished. The ...

    Biological control of Botrytis cinerea using the antagonistic and endophytic Burkholderia cepacia Cs5 for vine plantlet protection 

    Kilani-Feki, Olfa; Jaoua, Samir ( Canadian Science Publishing , 2011 , Article)
    Antifungal activity of the Burkholderia cepacia Cs5 was tested in vitro and in vivo for the control of Botrytis cinerea . Bacterial biomass was significantly improved by the amendment of ZnSO(4), Mo(7)(NH(4))(6)O(24), and ...

    Environmental Burkholderia cepacia strain CS5 acting by two analogous alkyl-quinolones and a didecyl-phthalate against a broad spectrum of phytopathogens fungi 

    Kilani-Feki, Olfa; Culioli, Gerald; Ortalo-Magne, Annick; Zouari, Nabil; Blache, Yves; Jaoua, Samir... more authors ... less authors ( Springer-Verlag , 2011 , Article)
    An environmental Burkholderia cepacia strain named Cs5 was isolated and identified first using API biochemical identification system and then with 16S rDNA and recA sequence homology search. This bacterium exhibited a broad ...

    Increase of the Bacillus thuringiensis secreted toxicity against lepidopteron larvae by homologous expression of the vip3LB gene during sporulation stage 

    Sellami, Sameh; Jamoussi, Kais; Dabbeche, Emna; Jaoua, Samir ( Springer-Verlag , 2011 , Article)
    The Vegetative insecticidal Vip3A proteins display a wide range of insecticidal spectrum against several agricultural insect pests. The fact that the expression of vip3 genes occurs only during the vegetative growth phase ...

    Improvement of Bacillus thuringiensis bioinsecticide production by sporeless and sporulating strains using response surface methodology 

    Ben Khedher, Saoussen; Kamoun, Amel; Jaoua, Samir; Zouari, Nabil ( Elsevier B.V. , 2011 , Article)
    Statistical experimental designs, involving a Plackett-Burman design followed by a rotatable central composite design were used to optimize the culture medium constituents for Bacillus thuringiensis bioinsecticide production. ...

    Overcoming the production limitations of Photorhabdus temperata ssp. temperata strain K122 bioinsecticides in low-cost medium 

    Jallouli, Wafa; Jaoua, Samir; Zouari, Nabil ( Springer-Verlag , 2011 , Article)
    For low-cost production of Photorhabdus temperata ssp. temperata strain K122 bioinsecticide, a cheap complex medium was optimized. Diluted seawater was used as the source of micronutrients, especially sodium chloride, ...

    Construction of a Bacillus thuringiensis genetically-engineered strain harbouring the secreted Cry1Ia delta-endotoxin in its crystal 

    Dammak, Mariam; Jaoua, Samir; Tounsi, Slim ( Springer Netherlands , 2011 , Article)
    Unlike other Bacillus thuringiensis Cry proteins, Cry1 Ia does not form a crystal since it is a secreted delta-endotoxin. We have engineered a Cry1 Iac chimeric protein by substituting the C-terminal part of Cry1 Ia by the ...
