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 ...
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, ...
Purification and characterization of a new Bacillus thuringiensis bacteriocin active against Listeria monocytogenes, Bacillus cereus and Agrobacterium tumefaciens
(
Springer Science
, 2011 , Article)
This study reports on the identification, characterization and purification of a new bacteriocin, named Bacthuricin F103, from a Bacillus thuringiensis strain BUPM103. Bacthuricin F103 production began in the early exponential ...
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 ...
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 ...
A complete sequence of the 16S rRNA gene of a novel Streptomyces coelicolor (AB588124) (QU66c-2002) isolated from the soil of Qatar
(
Asian Network for Scientific Information
, 2011 , Article)
The aim of this study was to determine the sequence of the 16S rRNA gene and thus to conduct the phylogenic position of the naturally occurring wild type strain of Streptomyces QU66C. Here we show conclusively the full ...
