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 ...
Comparative study of Bacillus thuringiensis Cry1Ia and Cry1Aa delta-endotoxins : activation process and toxicity against Prays oleae
(
Elsevier Inc.
, 2010 , Article)
Cry1Ia and Cry1Aa proteins exhibited toxicities against Prays oleae with LC(50) of 189 and 116 ng/cm(2), respectively. The ability to process Cry1Ia11 protoxin by trypsin, chymotrypsin and P. oleae larvae proteases was ...
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 ...
The effect of aluminum oxide on red blood cell integrity and hemoglobin structure at nanoscale
(
Elsevier B.V.
, 2019 , Article)
Herein, we explored the interaction of Al2O3 NPs with RBCs and Hb to determine the effect of Al2O3 NPs on hemolytic activity and Hb denaturation. The percentage of hemolysis of extracts and direct contact assays triggered ...
Agrotis segetum midgut putative receptor of Bacillus thuringiensis vegetative insecticidal protein Vip3Aa16 differs from that of Cry1Ac toxin
(
Elsevier Inc.
, 2013 , Article)
Considering the fact that Agrotis segetum is one of the most pathogenic insects to vegetables and cereals in the world, particularly in Africa, the mode of action of Vip3Aa16 of Bacillus thuringiensis BUPM95 and Cry1Ac of ...
Neonicotinoid insecticides in the environment: A critical review of their distribution, transport, fate, and toxic effects
(
Elsevier
, 2022 , Article)
Neonicotinoid insecticides (NENIs) have become increasingly common in recent decades in the control of crop pests and other plant pathogens. It is undeniable that the practice improves crop yield and economic productivity ...
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, ...
Biocompatibility and toxicity of novel iron chelator Starch-Deferoxamine (S-DFO) compared to zinc oxide nanoparticles to zebrafish embryo: An oxidative stress based apoptosis, physicochemical and neurological study profile.
(
Elsevier
, 2019 , Article)
Clinically approved iron chelators are effective in decreasing significant transfusional iron accumulation. Starch-Deferoxamine (S-DFO), a novel high molecular weight iron chelator, was produced to increase binding capacity ...
Nanozyme-based sensing platforms for detection of toxic mercury ions: An alternative approach to conventional methods
(
Elsevier B.V.
, 2020 , Article)
Mercury (Hg) is known as a poisonous heavy metal which stimulates a wide range of adverse effects on the human health. Therefore, development of some feasible, practical and highly sensitive platforms would be desirable ...
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 ...
