Lipopeptide production by Bacillus subtilis R1 and its possible applications
The possible application of a bacterial strain - Bacillus subtilis R1, isolated from an oil contaminated desert site in India, as biocontrol agent and its biosurfactant in microbial enhanced oil recovery are discussed. The biosurfactant production in minimal medium was carried out at different temperatures and salt concentrations, where it produced an efficient biosurfactant at 30-45°C and in p...
متن کاملOptimization of spore and antifungal lipopeptide production during the solid-state fermentation of Bacillus subtilis.
Bacillus subtilis strain TrigoCor 1448 was grown on wheat middlings in 0.5-l solid-state fermentation (SSF) bioreactors for the production of an antifungal biological control agent. Total antifungal activity was quantified using a 96-well microplate bioassay against the plant pathogen Fusarium oxysporum f. sp. melonis. The experimental design for process optimization consisted of a 2(6-1) fract...
متن کاملCost-effective medium for the production of mosquito pupicidal lipopeptide from Bacillus subtilis subsp. subtilis (VCRC B471).
BACKGROUND & OBJECTIVES A cyclic lipopeptide (CLP), surfactin produced by a strain of Bacillus subtilis subsp. subtilis (VCRC B471) was found to exhibit mosquitocidal activity. The present study was carried out to enhance the surfactin level using low cost material in the production medium. METHODS Two carbon sources, glucose and common sugar, and two nitrogen sources, ammonium nitrate and so...
متن کاملProduction, purifi cation, and characterization of α-amylase by Bacillus subtilis and its mutant derivates
Th e eff ects of various carbon and nitrogen sources on production of α-amylase by Bacillus subtilis and its mutant derivates were investigated. Th e maximum production of α-amylase by all strains was obtained in the presence of mesoinositol as the carbon source. Th ere was no more signifi cant increase in enzyme yield in the case of the supplementation of nitrogen sources, whereas malt extract...
متن کاملFengycin--a novel antifungal lipopeptide antibiotic produced by Bacillus subtilis F-29-3.
Fengycin is an antifungal lipopeptide complex produced by Bacillus subtilis strain F-29-3. It inhibits filamentous fungi but is ineffective against yeast and bacteria. The inhibition is antagonized by sterols, phospholipids and oleic acid, whereas two other unsaturated fatty acids increase the antifungal effect. Fengycin consists of two main components differing by one amino acid exchange. Feng...
