Overproduction of Delta-Endotoxins by Sporeless Bacillusthuringiensis Mutants Obtained by Nitrous Acid Mutagenesis
(
Springer-Verlag
, 2011 , Article)
Asporogenic and oligosporogenic Bacillus thuringiensis mutants having the ability to overproduce insecticidal crystal protein were generated by using nitrous acid (50 mg/ml), as chemical mutagenic agent. Insecticidal crystal ...
Antifungal activities of an endophytic Pseudomonas fluorescens strain Pf1TZ harbouring genes from pyoluteorin and phenazine clusters
(
Springer Netherlands
, 2010 , Article)
Pseudomonas fluorescens Pf1TZ was inhibitory in vitro to a number of phytopathogenic fungi and could protect vine plantlets against Botrytis cinerea. Total protection was reached after 3 weeks of bacterial inoculation. The ...
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 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 ...
Overcome of carbon catabolite repression of bioinsecticides production by sporeless Bacillus thuringiensis through adequate fermentation technology
(
Hindawi Publishing Corporation
, 2014 , Article)
The overcoming of catabolite repression, in bioinsecticides production by sporeless Bacillus thuringiensisstrain S22 was investigated
into fully controlled 3 L fermenter, using glucose based medium. When applying adequate ...
Application of statistical experimental design for optimisation of bioinsecticides production by sporeless Bacillus thuringiensis strain on cheap medium
(
Sociedade Brasileira de Microbiologia - SBM
, 2014 , Article)
In order to overproduce bioinsecticides production by a sporeless Bacillus thuringiensis strain, an optimal composition of a cheap medium was defined using a response surface methodology. In a first step, a Plackett-Burman ...
Correlation between delta-endotoxin and proteolytic activities produced by Bacillus thuringiensis var. kurstaki growing in an economic production medium
(
Taylor & Francis
, 2013 , Article)
Bacillus thuringiensis is a Gram positive bacterium that produces an insecticidal crystalline protein making it one of the most important biocontrol agents for pest management. Bioinsecticides based on B. thuringiensis ...
