“…B. subtilis B20 and B30 produced between 0.3 and 2.3 g/l of biosurfactant using a mineral medium supplemented with date molasses as carbon source (Al-Bahry et al, 2013;Al-Wahaibi et al, 2014). Abdel-Mawgoud et al (2008) reported a biosurfactant production of 1.12 g/l by B. subtilis BS5 using a mineral medium containing sugarcane molasses.…”

“…Consequently, surfactin can be potentially useful in numerous therapeutic, industrial, and environmental applications. In order to reduce the production costs, surfactin production by B. subtilis strains has been studied using different substrates, such as molasses (AbdelMawgoud et al, 2008;Al-Bahry et al, 2013), potato peels (Das and Mukherjee, 2007), whey powder (CagriMehmetoglu et al, 2012), cashew apple juice (Oliveira et al, 2013) or cassava waste water . Furthermore, the effect of different nutritional factors has been studied to improve surfactin production by B. subtilis strains.…”

“…Presently, biosurfactants are not competitive with chemical surfactants from an economic point of view, since expensive substrates are required for their production and they present relatively low productivities, which hampers their widespread use and commercialization. As the culture medium can account for up to 30-50% of the overall production costs of biosurfactants, the replacement of expensive synthetic media by cheaper agro-industrial wastes and by-products can contribute to reduce their production costs and increase their competitiveness Al-Bahry et al, 2013;Gudiña et al, 2015).Biosurfactants display a wide variety of chemical structures, including glycolipids, lipopeptides, phospholipids, fatty acids, or neutral lipids, among others Geys et al, 2014). Bacillus species produce a broad spectrum of lipopeptide biosurfactants, which are cyclic molecules consisting of a fatty acid of variable length (hydrophobic moiety) linked to a short peptide chain (hydrophilic moiety) of seven or ten aminoacids.…”

PublisherFrontiers in Microbiology About FrontiersFrontiers is more than just an open-access publisher of scholarly articles: it is a pioneering approach to the world of academia, radically improving the way scholarly research is managed. The grand vision of Frontiers is a world where all people have an equal opportunity to seek, share and generate knowledge. Frontiers provides immediate and permanent online open access to all its publications, but this alone is not enough to realize our grand goals. Frontiers Journal SeriesThe Frontiers Journal Series is a multi-tier and interdisciplinary set of open-access, online journals, promising a paradigm shift from the current review, selection and dissemination processes in academic publishing. All Frontiers journals are driven by researchers for researchers; therefore, they constitute a service to the scholarly community. At the same time, the Frontiers Journal Series operates on a revolutionary invention, the tiered publishing system, initially addressing specific communities of scholars, and gradually climbing up to broader public understanding, thus serving the interests of the lay society, too. Dedication to QualityEach Frontiers article is a landmark of the highest quality, thanks to genuinely collaborative interactions between authors and review editors, who include some of the world's best academicians. Research must be certified by peers before entering a stream of knowledge that may eventually reach the public -and shape society; therefore, Frontiers only applies the most rigorous and unbiased reviews. Frontiers revolutionizes research publishing by freely delivering the most outstanding research, evaluated with no bias from both the academic and social point of view. By applying the most advanced information technologies, Frontiers is catapulting scholarly publishing into a new generation. What are Frontiers Research Topics?Frontiers Research Topics are very popular trademarks of the Frontiers Journals Series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area!

They are secondary metabolites that accumulate at interfaces, reduce surface tension and form micellar aggregates. This research topic describes few novel microbial strains with a focus on increasing our understanding of genetics, physiology, regulation of biosurfactant production and their commercial potentials. A major stumbling block in the commercialization of b...

“…Mouafi et al [1] reported that lipopeptide biosurfactant production from Bacillus brevis was increased by glucose supplementation in medium. The lipopeptide biosurfactant yield of Bacillus subtilis B20 was increased to 2.29 g/L when cultured with molasses [5]. Karanja oil was also able to increase the biosurfactant yield of Pseudomonas aeruginosa KVD-HR42 to 5.90 g/L [3].…”

Abstract-To enhance lipopetide biosurfactant production by Pseudomonas spp., the effects of medium and culture conditions were investigated. Nutrient broth (NB) supplemented with glucose and molasses as carbon sources were used to increase biosurfactant yield. Cultivation temperatures and initial pH were also studied. In this experiment, NB was used as a control to produce biosurfactant with the yield of 0.58 g/L. The lipopeptide biosurfactant yield was increased to 2.76 g/L when Pseudomonas spp. was cultured in NB supplemented with 1% w/v glucose, 500 µM FeSO4, pH 9.0 and cultivation of 20°C for 72 h. Its specific growth rate was 0.25 h-1.Index Terms-Pseudomonas spp., lipopeptide biosurfactant, glucose, ferrous.
