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 ...
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 ...
Adsorption of ochratoxin A from grape juice by yeast cells immobilised in calcium alginate beads
(
Elsevier
, 2016 , Article)
Grape juice can be easily contaminated with ochratoxin A (OTA), one of the known mycotoxins with the greatest public health significance. Among the different approaches to decontaminate juice from this mycotoxin, microbiological ...
Cry1Ac toxicity enhancement towards lepidopteran pest Ephestia kuehniella through its protection against excessive proteolysis
(
Elsevier
, 2016 , Article)
Bacillus thuringiensis has been extensively used in agroecosystems for four decades due to its high specific toxicity. Strategies based on B. thuringiensis proteins combinations for the improvement of its activity present ...
Application of yeasts and yeast derivatives for the biological control of toxigenic fungi and their toxic metabolites
(
Elsevier
, 2021 , Article)
Mycotoxins, the metabolites of toxigenic fungi are important contaminants of food and agriculture industry throughout the world. Among the different strategies to minimize the mycotoxins synthesis and decontamination of ...
Application of low-fermenting yeast Lachancea thermotolerans for the control of toxigenic fungi Aspergillus parasiticus, Penicillium verrucosum and Fusarium graminearum and their mycotoxins
(
MDPI
, 2018 , Article)
© 2018 by the authors. Licensee MDPI, Basel, Switzerland. Mycotoxins are important contaminants of food and feed. In this study, low fermenting yeast (Lachancea thermotolerans) and its derivatives were applied against ...
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 ...
Influence of temperature, salinity and Mg:Ca ratio on microbially-mediated formation of Mg-rich carbonates by Virgibacillus strains isolated from a sabkha environment.
(
Nature Research
, 2019 , Article)
Studies have demonstrated that microbes facilitate the incorporation of Mg into carbonate minerals, leading to the formation of potential dolomite precursors. Most microbes that are capable of mediating Mg-rich carbonates ...
Toxin stability improvement and toxicity increase against dipteran and lepidopteran larvae of Bacillus thuringiensis crystal protein Cry2Aa
(
John Wiley and Sons Ltd
, 2016 , Article)
BACKGROUND: Bacillus thuringiensis ?-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 ...
Diversity of Bacillus thuringiensis Strains From Qatar as Shown by Crystal Morphology, d-Endotoxins and Cry Gene Content
(
Frontiers Media
, 2018 , Article)
Bacillus thuringiensis (Bt) based insecticidal formulations have been recognized as one of
the most successful, environmentally safe and sustainable method of controlling insect
pests. Research teams worldwide are in ...
