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 ...
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 ...
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 ...
Minimizing wind erosion using microbial induced carbonate precipitation
(
American Society of Civil Engineers (ASCE)
, 2019 , Conference Paper)
This research focuses on investigating the effectiveness of microbial-induced carbonate precipitation (MICP) to reduce the potential for wind erosion. This paper summarizes the results of preliminary wind tunnel experiments. ...
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 ...
Improvement of Bacillus thuringiensis bioinsecticide production by sporeless and sporulating strains using response surface methodology
(
Elsevier B.V.
, 2011 , Article)
Statistical experimental designs, involving a Plackett-Burman design followed by a rotatable central composite design were used to optimize the culture medium constituents for Bacillus thuringiensis bioinsecticide production. ...
Combinatorial effect of mutagenesis and medium component optimization on Bacillus amyloliquefaciens antifungal activity and efficacy in eradicating Botrytis cinerea
(
Elsevier GmbH
, 2017 , Article)
This work is directed towards Bacillus amyloliquefaciens strain BLB371 metabolite production for biocontrol of fungal phytopathogens. In order to maximise antifungal metabolite production by this strain, two approaches ...
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 ...
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 ...
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, ...
