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 ...
Toxin stability improvement and toxicity increase against dipteran and lepidopteran larvae of Bacillus thuringiensis crystal protein Cry2Aa
(
Wiley
, 2016 , Article)
BACKGROUND
Bacillus thuringiensis δ-endotoxins are the most widely used biopesticides for controlling economically important crop pests and disease vectors. Improving their efficacy is of great benefit. Here, an improvement ...
Bayesian network and response surface methodology for prediction and improvement of bacterial metabolite production
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
The optimization of antifungal activity production by Bacillus amyloliquefaciens was carried out using Response Surface Methodology (RSM) in two steps. The first step involved the screening of cultural parameters affecting ...
Overproduction of the Bacillus thuringiensis Vip3Aa16 toxin and study of its insecticidal activity against the carob moth Ectomyelois ceratoniae
(
Elsevier
, 2015 , Article)
The vip3Aa16 gene of Bacillus thuringiensis strain BUPM95 was cloned and expressed in Escherichia coli. Optimization of Vip3A16 protein expression was conducted using Plackett–Burman design and response surface methodology. ...
Potential of Photorhabdus temperata K122 bioinsecticide in protecting wheat flour against Ephestia kuehniella
(
Elsevier Ltd
, 2013 , Article)
The present study reports investigations on the insecticidal activity of the entomopathogenic bacterium Photorhabdus temperata K122 against the Mediterranean flour moth Ephestia kuehniella. Cultured in the optimized medium, ...
Cry4Ba and Cyt1Aa proteins from Bacillus thuringiensis israelensis: Interactions and Toxicity mechanism against Aedes aegypti
(
Elsevier Ltd
, 2015 , Article)
Individual crystal proteins from Bacillus thuringiensis israelensis exhibit variable levels of insecticidal activities against mosquito larvae. In all cases, they are much less active compared to the whole crystal proteins ...
Synthesis of silver nanoparticles using Bacillus velezensis M3-7 lipopeptides: Enhanced antifungal activity and potential use as a biocontrol agent against Fusarium crown rot disease of wheat seedlings
(
Elsevier
, 2023 , Article)
Bacillus velezensis M3-7 is a hyperactive mutant, 12-fold improved in its antifungal activity, obtained during a previous study from the wild strain BLB371 after a combination of random mutagenesis and medium component ...
Histopathological effects and determination of the putative receptor of Bacillus thuringiensis Cry1Da toxin in Spodoptera littoralis midgut
(
Elsevier
, 2012 , Article)
Bacillus thuringiensis subsp. aizawai strain HD133, known by its effectiveness against Spodoptera species, produces many insecticidal proteins including Cry1Ab, Cry1Ca and Cry1Da. In the present study, the insecticidal ...
Halobacteria-Based Biofertilizers: A Promising Alternative for Enhancing Soil Fertility and Crop Productivity under Biotic and Abiotic Stresses—A Review
(
MDPI
, 2023 , Other)
Abiotic and biotic stresses such as salt stress and fungal infections significantly affect plant growth and productivity, leading to reduced crop yield. Traditional methods of managing stress factors, such as developing ...
