Biological control of Botrytis cinerea using the antagonistic and endophytic Burkholderia cepacia Cs5 for vine plantlet protection
(
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 ...
Antioxidant constituents from Lawsonia inermis leaves: Isolation, structure elucidation and antioxidative capacity
(
Elsevier Ltd
, 2011 , Article)
The antioxidant potential of different fractions of Lawsonia inermis (Lythraceae) was investigated. The n-butanolic fraction showed the highest yield of extraction; it also exhibited a strong antioxidant activity in the ...
Environmental Burkholderia cepacia strain CS5 acting by two analogous alkyl-quinolones and a didecyl-phthalate against a broad spectrum of phytopathogens fungi
(
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 ...
Overcoming the production limitations of Photorhabdus temperata ssp. temperata strain K122 bioinsecticides in low-cost medium
(
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, ...
Increase of the Bacillus thuringiensis secreted toxicity against lepidopteron larvae by homologous expression of the vip3LB gene during sporulation stage
(
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 Bioinsecticides Production by Sporeless Bacillus thuringiensis strains in Response to Various Stresses in Low Cost Medium
(
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 ...
Characterization of bioactive compounds and ameliorative effects of Ceratonia siliqua leaf extract against CCl4 induced hepatic oxidative damage and renal failure in rats
(
Elsevier Ltd
, 2011 , Article)
Ceratonia siliqua is a typical Mediterranean plant, mainly used in food and Tunisian traditional folk medicine. Among the tested extracts, the ethyl acetate fraction (EACs) exhibited the highest total phenolic and flavonoids ...
Improvement of Bacillus thuringiensis bioinsecticide production by sporeless and sporulating strains using response surface methodology
(
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. ...
Construction of a Bacillus thuringiensis genetically-engineered strain harbouring the secreted Cry1Ia delta-endotoxin in its crystal
(
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 ...
Chemical composition, cytotoxicity effect and antimicrobial activity of Ceratonia siliqua essential oil with preservative effects against Listeria inoculated in minced beef meat
(
Elsevier B.V.
, 2011 , Article)
The present study describes the phytochemical profile and the protective effects of Ceratonia siliqua pods essential oil (CsEO), a food and medicinal plant widely distributed in Tunisia. Twenty five different components ...
