Application of statistical experimental design for optimisation of bioinsecticides production by sporeless Bacillus thuringiensis strain on cheap medium
Khedher, Saoussen Ben; Jaoua, Samir; Zouari, Nabil (2013 , 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 ... -
Combinatorial effect of mutagenesis and medium component optimization on Bacillus amyloliquefaciens antifungal activity and efficacy in eradicating Botrytis cinerea
Masmoudi, Fatma; Khedher, Saoussen Ben; Kamoun, Amel; Zouari, Nabil; Tounsi, Slim; Trigui, Mohamed... more authors ... less authors ( 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 ... -
Overcome of carbon catabolite repression of bioinsecticides production by sporeless Bacillus thuringiensis through adequate fermentation technology
Khedher, Saoussen Ben; Jaoua, Samir; Zouari, Nabil ( 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 ... -
