Surfactin and fengycin lipopeptides of Bacillus subtilis as elicitors of induced systemic resistance in plants.
Experiments conducted on bean and tomato plants showed that overexpression of both surfactin and fengycin biosynthetic genes in the naturally poor producer Bacillus subtilis strain 168 was associated with a significant increase in the potential of the derivatives to induce resistance. Expand
Involvement of fengycin-type lipopeptides in the multifaceted biocontrol potential of Bacillus subtilis
Evidence is provided for the role of secreted lipopeptides, and more particularly of fengycins, in the protective effect afforded by the strain against damping-off of bean seedlings caused by Pythium ultimum and against gray mold of apple in post-harvest disease. Expand
PAMPs, MAMPs, DAMPs and others: an update on the diversity of plant immunity elicitors
La comprehension des bases physiologiques et biologiques des mecanismes de ces immunites a beaucoup progresse ces dernieres annees, mais une connaissance plus approfondie des me canismes sous-jacents a the perception of ces eliciteurs est cependant essentielle pour developper de nouveaux moyens de controle des nuisibles.

Role of lipopeptides produced by Bacillus subtilis GA1 in the reduction of grey mould disease caused by Botrytis cinerea on apple
Test of Bacillus subtilis strain GA1 for its potential to control grey mould disease of apple caused by Botrytis cinerea finds it to be a good candidate for control. Expand
Antioxidant phenolic compounds loss during the fermentation of Chétoui olives
Abstract Evolution of phenolic compounds was studied during spontaneous and controlled fermentations of “Chetoui” cultivar olives at three degree of ripeness. Both spontaneous and controlledExpand
Optimization of biosurfactant lipopeptide production from Bacillus subtilis S499 by Plackett-Burman design
The analysis of the surfactant molecules produced in such optimized conditions has revealed the presence of a third family of lipopeptides: the fengycins in Bacillus subtilis S499. Expand
Characterisation and biochemical properties of predominant lactic acid bacteria from fermenting cassava for selection as starter cultures.
Biochemical properties such as production of alpha-amylase, beta-glucosidase, tannase, antimicrobials, acidification and fermentation of the indigestible sugars raffinose and stachyose, were evaluated in vitro for selection of potential starter strains for Gari production. Expand
Influence of culture conditions on lipopeptide production by Bacillus subtilis
This study studied the effects of different media on the nature of the synthesis of fatty acid chains for each lipopeptide family and found that the intensity of production of homologous compounds depends on the strain and the culture medium. Expand
The analysis of crude and purified locust bean gum: A comparison of samples from different carob tree populations in Tunisia
Abstract The crude and purified locust bean gum (LBG) from seven areas of the north and centre of Tunisia (Bouarada, Bargou, Kessra, Haffouz, Borj Toumi, Ben Arous and INRGREF) were analyzed forExpand
Characteristics of African traditional beers brewed with sorghum malt: a review
Cette revue bibliographique s’adapte egalement au progres accompli dans l’amelioration des bieres traditionnelles africaines a base of sorgho. Expand
