Statistical Analysis of Cultural Parameters Influencing Delta-Endotoxins and Proteases Productions by Bacillus thuringiensis kurstaki
(
Springer Verlag
, 2016 , Article)
Bacillus thuringiensis is a spore-forming bacterium that produces delta-endotoxins, which are toxic to lepidopterans, dipterans and coleopterans. Concomitantly with production of delta-endotoxins, B. thuringiensis produces ...
Use of DPSIR Framework to Analyze Water Resources in Qatar and Overview of Reverse Osmosis as an Environment Friendly Technology
(
John Wiley and Sons Inc.
, 2019 , Article Review)
Qatar and other countries of Gulf Cooperation Council are among the most water scarce countries in the world and are being characterized as “high‐water risk” countries by Water Resource Institute. Therefore, it is important ...
A MALDI-TOF study of bio-remediation in highly weathered oil contaminated soils
(
Elsevier
, 2018 , Article)
We have shown that Bacillus cereus is dominating the bacterial population at three polluted oil-industry sites
where weather and soil conditions are extreme in terms of temperature, UV-radiation and salinity. A minor ...
Nutritional Requirements to Improve Delta-Endotoxins Production of Bacillus thuringiensis var. kurstaki Using Mixed Designs Modelling
(
Springer India
, 2017 , Article)
Bacillus thuringiensiskurstaki is a soil bacterium that produces insecticidal toxins called delta-endotoxins. In order to increase the toxic crystal concentrations in a low-cost culture medium and thus improve the biopesticide ...
Multiple linear regression and artificial neural networks for delta-endotoxin and protease yields modelling of Bacillus thuringiensis
(
Springer Verlag
, 2017 , Article)
The aim of the present work was to develop a model that supplies accurate predictions of the yields of delta-endotoxins and proteases produced by B. thuringiensis var. kurstaki HD-1. Using available medium ingredients as ...
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, ...
Involvement of oxidative stress and growth at high cell density in the viable but nonculturable state of Photorhabdus temperata ssp. temperata strain K122
(
Elsevier Ltd
, 2010 , Article)
Photorhabdus temperata ssp. temperata strain K122 represents a promising source of bioinsecticide. When cultured in an optimized medium, P. temperata exhibited restricted survival in terms of colony-forming ability on solid ...
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 Bioinsecticides Production by Sporeless Bacillus thuringiensis strains in Response to Various Stresses in Low Cost Medium
(
Springer-Verlag
, 2011 , Article)
The use of bioinsecticides, particularly those produced by sporeless Bacillus thuringiensis strains, has been shown to be a good alternative in pest management. Two types of sporeless mutants were distinguished. The ...
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 ...
