Isolation of entomopathogenic Bacillus from a biodynamic olive farm and their pathogenicity to lepidopteran and coleopteran insect pests
(
Elsevier Ltd
, 2012 , Article)
The occurrence of Bacillus entomopathogenic bacteria on a Tunisian biodynamic farm was determined by examining 75 samples from olive tree (Olea europaea L.) habitats. A total of 40 Bacillus isolates were characterized ...
Improvement of Photorhabdus temperata bioinsecticides production in low-cost media through adequate fermentation technology
(
Wiley Subscription Services, Inc.
, 2012 , Article)
To develop a cost effective process for bioinsecticides production by Photorhabdus temperata, dissolved oxygen (DO) requirements were investigated in both the complex and the optimized media using diluted seawater as a ...
Amino acids Y229 and F603 are involved in Bacillus thuringiensis Cry1Ac delta-endotoxin stability and toxicity
(
Blackwell Publishing
, 2012 , Article)
Bacillus thuringiensis Cry1Ac toxin shares structurally five conserved blocs with the other δ-endotoxins. To study the role of some amino acids belonging to these regions, two mutations, Y(229) P and F(603) S, were introduced ...
Differential oxidative stress responses to methanol in intraperitoneally exposed rats: Ameliorative effects of Opuntia vulgaris fruit extract
(
SAGE Publications
, 2012 , Article)
Methanol is primarily metabolized by oxidation to formaldehyde and then to formate. These processes are accompanied by formation of superoxide anion and hydrogen peroxide. This article reports data on the effect of ...
Use of two bacteria for biological control of bayoud disease caused by Fusarium oxysporum in date palm (Phoenix dactylifera L) seedlings
(
Elsevier Masson SAS
, 2012 , Article)
The Bayoud, caused by Fusarium oxysporum f. sp. albedinis (Foa), is the most destructive disease of date palm (Phoenix dactylifera L) in Morocco and Algeria, with no effective control strategy yet available. In this work, ...
Correlation between synthesis variation of 2-alkylquinolones and the antifungal activity of aBurkholderia cepacia strain collection
(
Springer Netherlands
, 2012 , Article)
Twenty epiphytic and rhizospheric bacterial strains harbouring strong antifungal activities were isolated from the Tunisian environment. This group of bacteria was identified as Burkholderia cepacia genomovar I using 16S ...
Improvement of Photorhabdus temperata strain K122 bioinsecticide production by batch and fed-batch fermentations optimization
(
Springer-Verlag
, 2012 , Article)
Optimization of a fermentation process for bioinsecticides production by Photorhabdus temperata strain K122 was investigated into fully controlled 3-L fermenter using an optimized medium (OM). Development of large-scale ...
