“…They play an important role in protection against desiccation [2] and also useful in forming biofilms [3,4]. Their various applications include use as gelling agents, biosurfactants, emulsifiers, viscosifiers [5][6][7], biosorbants [8,9], biologically active antimicrobials, anticancer agents and antioxidants [10][11][12][13].…”

Objective: To study 1) Optimization of nutritional and environmental parameters to enhance the yield of EPS by Halomonas smyrnensis SVD III isolated from seawater, West Coast of Maharashtra, India and 2) Purification and characterization of the EPS produced. Methods:The isolate was grown in Sehgal and Gibbons (SG) medium broth supplemented with 3% glucose, at 37 °C, 120 rpm for 7 d. Optimization of different parameters was carried out with one factor at a time approach. EPS was isolated from cell-free supernatant of the culture broth by centrifugation and precipitation using chilled ethanol, after removal of proteins by trichloroacetic acid (TCA) treatment. Characterization of the purified EPS was carried out with respect to fourier-transform infrared (FTIR) spectrum, 1 H nuclear magnetic resonance (NMR) spectrum and mass spectrometry (MS) analysis.Results: Two-fold increase in the yield of EPS (23 g/l) by the selected isolate was obtained by using culture conditions as 10% inoculum size having cell density of 10 7 cells/ml, pH 6, incubation temperature 45 °C, 3% carbohydrate, 0.5% yeast extract as nitrogen source, 20% salt concentration and 7 d of incubation period. Characterization of the purified EPS suggested the presence of dominated glycosidic linkages and heptasaccharide nature of the molecule. As the present strain is halophilic, 20% NaCl was found to be optimum. Conclusion:Optimization studies resulted in two-fold increase in the yield of EPS which is of heptasaccharide nature.

“…Similar observations were reported by Babu et al (1996) and Dubey and Juwarkar (2001) Although using dairy and distillery waste for various BS productions is possible, difficulties may arise when attempting to purify or collect such products. BSs recovery methods are diverse and include solvent extraction, precipitation, crystallization, centrifugation, and foam fractionation (Satpute et al, 2010a). However, Dubey and Juwarkar (2004) suggested that the various purification mentioned above cannot be effectively employed when using distillery wastewater as a nutrient medium for BS production.…”

“…However, this fact may not always be true. Ample literature available suggests that water soluble carbon sources like glucose, fructose, sucrose etc., can be used in synthesizing the amphiphilic substances from a variety of microbial populations (Satpute et al, , 2010a.From an industrial point of view, using water soluble substrates is more attractive compared with using immiscible substrates. Therefore, the use of water soluble substrates particularly inexpensive industrial waste such as whey, molasses, distilleries effluent, waste oils would help to bring down the production cost in industries.…”

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...

“…são espécies amplamente presentes em ecossistemas marinhos, contribuindo de forma relevante para microflora em frutos-do-mar (AUSTIN et al, 1979;THAMPURAN e GOPAKUMAR, 1993;CHOI, CHOI e LEE, 1996 O número de trabalhos relacionados à produção de BS a partir de microorganismos marinhos esta em constante expansão (Tabela 2.4).

“…Os micro-organismos presentes em ecossistemas ditos "extremos" como o ambiente marinho também tem sido objeto de pesquisa para produção de BS, se destacam por desenvolverem estratégias metabólicas que os fazem suportar ambientes limites para existência da vida e consequentemente produzir compostos com elevada atividade tensoativa em condições diversas, o que os tornam de grande interesse para indústria química (LAMBAIS et al, 2006;BAHARUM, BENG e MOKHTAR, 2010). Por essa razão, a busca por BS produzidos por micro-organismos marinhos tem aumentado progressivamente na última década, principalmente por apresentarem propriedades singulares como a atividade tensoativa estável em altas concentrações de eletrólitos, temperatura e pressão (SATPUTE et al, 2010a).…”
