BACKGROUND xopolysaccharides (EPS) are not a well-established group of metabolites. An industrial scale of this EPS production is limited mainly by low yield biosynthesis. Until now, enzymes and biosynthesis pathways, as well as the role of regulatory genes, have not been described. Some of yeast EPS show antitumor, immunostimulatory and antioxidant activity. Others, absorb heavy metals and ...
Rhizobium tropici, a member of the Rhizobiaceae family, has the ability to synthesize and secrete extracellular polysaccharides (EPS). Rhizobial EPS have attracted much attention from the scientific and industrial communities. Rhizobial isolates and R. tropici mutants that produced higher levels of EPS than the wild-type strain SEMIA4080 were used in the present study. The results suggested a h...
ISO 26262 is an international standard for the functional safety of electric and electronic systems in vehicles, and this standard has become a major issue in the automotive industry. In this paper, a functional safety compliant electronic control unit (ECU) for an electric power steering (EPS) system and a demonstration purposed EPS system are developed, and a software and hardware structure f...
Long intergenic noncoding RNAs (lincRNAs) are important regulators of gene expression. Although lincRNAs are expressed in immune cells, their functions in immunity are largely unexplored. Here, we identify an immunoregulatory lincRNA, lincRNA-EPS, that is precisely regulated in macrophages to control the expression of immune response genes (IRGs). Transcriptome analysis of macrophages from linc...
Zunongwangia profunda SM-A87 isolated from deep-sea sediment can secrete large quantity of exopolysaccharide (EPS). Response surface methodology was applied to optimize the culture conditions for EPS production. Single-factor experiment showed that lactose was the best carbon source. Based on the Plackett-Burman design, lactose, peptone and temperature were selected as significant variables, wh...
The paper illustrates this statement by presenting a brief description of an interface for METAFONT-to-PostScript, MFTOEPS. The kernel of the package is a METAFONT program (MFTOEPS.MF) which provides necessary definitions for translating the description of graphic objects from METAFONT to PostScript. The PostScript code is written to a log file. It can be extracted from the log file either manu...
"Slime" played a brief and spectacular role in the 19th century founded by the theory of primordial slime by Ernst Haeckel. However, that substance was never found and eventually abandoned. Further scientific attention slowly began in the 1930s referring to slime as a microbial product and then was inspired by "How bacteria stick" by Costerton et al. in 1978, and the matrix material was conside...
صمغ کتیرا و اگزوپلی ساکاریدها دارای خصوصیاتی هستند که می توانند جایگزین چربی در پنیر شوند. تاثیر صمغ کتیرا و آغازگر تولید کننده اگزوپلی ساکارید(EPS) بر خواص فیزیکوشیمیایی، بافتی و ریزساختاری پنیر چدار کم چرب طی دوره رسیدن مورد بررسی قرار گرفت. پنیر چدار در 5 تیمار، شامل تیمارهای کم چرب و پرچرب شاهد، حاوی 06/0 % صمغ کتیرا، حاوی آغازگر تولیدکننده EPS و حاوی 06/0 % صمغ کتیرا و آغازگر EPS به صورت ...
AIMS To investigate Klebsiella oxytoca strain BAS-10 growth on ferric citrate under anaerobic conditions for exopolysaccharide (EPS) production and localization on cell followed by the purification and the EPS determination of the iron-binding stability constant to EPS or biotechnological applications. METHODS AND RESULTS Klebsiella oxytoca ferments ferric citrate under anaerobic conditions a...
Streams are potential receiving compartments for engineered nanoparticles (NP). In streams, NP may remain dispersed or settle to the benthic compartment. Both dispersed and settling NP can accumulate in benthic biofilms called periphyton that are essential to stream ecosystems. Periphytic organisms excrete extracellular polymeric substances (EPS) that interact with any material reaching the bio...
