Isolation, screening and activity of hydrocarbon-degrading bacteria from harsh soils
(
Avestia Publishing
, 2016 , Conference Paper)
The study of microbial communities in relation to their ecology, interaction, and genetics must be covered in Qatar with special soil, weather and water. Microorganisms of an environment never having been exposed to such ...
Evidence of two mechanisms involved in Bacillus thuringiensis israelensis decreased toxicity against mosquito larvae: Genome dynamic and toxins stability
(
Elsevier GmbH
, 2015 , Article)
Biopesticides based on Bacillus thuringiensis israelensis are the most used and most successful around the world. This bacterium is characterized by a dynamic genome able to win or lose genetic materials which leads to a ...
Towards novel Cry toxins with enhanced toxicity/broader: a new chimeric Cry4Ba / Cry1Ac toxin
(
Springer-Verlag
, 2017 , Article)
Attempts have been made to express or to merge different Cry proteins in order to enhance toxic effects against various insects. Cry1A proteins of Bacillus thuringiensis form a typical bipyramidal parasporal crystal and ...
New Bacillus thuringiensis toxin combinations for biological control of Lepidopteran larvae
(
Elsevier B.V.
, 2014 , Article)
Cyt1Aa from Bacillus thuringiensis israelensis is known by its synergistical activity with B. thuringiensis and Bacillus sphaericus toxins. It is able to improve dipteran specific toxins activity and can prevent or overcome ...
Low electro-synthesis potentials improve permselectivity of polymerized natural phenols in biosensor applications
(
Elsevier
, 2017 , Article)
First-generation amperometric biosensors are often based on the electro-oxidation of oxidase-generated H2O2. At the applied potential used in most studies, other molecules such as ascorbic acid or dopamine can be oxidized. ...
Screening and identification of a Bacillus thuringiensis strain S1/4 with large and efficient insecticidal activities.
(
WILEY-VCH
, 2013 , Article)
The bacterium Bacillus thuringiensis was recognized for its entomopathogenic activities related to Cry and Cyt proteins forming the δ-endotoxins and some extracellular activities like the vegetative insecticidal proteins ...
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 ...
Effects of the P20 protein from Bacillus thuringiensis israelensis on insecticidal crystal protein Cry4Ba
(
Elsevier B.V.
, 2015 , Article)
The accessory protein P20 from Bacillus thuringiensis israelensis has been defined as an important molecular chaperone for forming crystal Cyt1Aa, and enhancing Cry11Aa and Cry4Aa expression. To investigate its putative ...
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 ...
Efficacy of Lawsonia inermis leaves extract and its phenolic compounds against olive knot and crown gall diseases.
(
Elsevier
, 2013 , Article)
This study was undertaken to determine the antibacterial efficacy of the leaves extracts of Lawsonia inermis in vitro and in vivo, against the phytopathogenic bacteria Pseudomonas savastanoi pv savastanoi IVIA 1628 and ...
