Role of extracellular polymeric substances in bioflocculation of activated sludge microorganisms under glucose-controlled conditions
Appala Raju Badireddy,Shankararaman Chellam,Paul L. Gassman,Mark H. Engelhard,Alan S. Lea,Kevin M. Rosso +5 more
TL;DR: EPS secreted by suspended cultures of microorganisms from an activated sludge plant in the presence of glucose were characterized in detail using colorimetry, X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared (FTIR) Spectroscopy.
Journal ArticleDOI
Spectroscopic characterization of extracellular polymeric substances from Escherichia coli and Serratia marcescens: suppression using sub-inhibitory concentrations of bismuth thiols.
Appala Raju Badireddy,Bhoom Reddy Korpol,Shankararaman Chellam,Paul L. Gassman,Mark H. Engelhard,Alan S. Lea,Kevin M. Rosso +6 more
TL;DR: In this paper, free and bound EPS produced by suspended cultures of Escherichia coli and Serratia marcescens were characterized in detail using colorimetric analysis of total proteins and polysaccharides, Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectrography (XPS), and Auger electron spectrograms (AES) in the presence and absence of bismuth-based antifouling agents.
Journal ArticleDOI
Bismuth Dimercaptopropanol (BisBAL) Inhibits the Expression of Extracellular Polysaccharides and Proteins by Brevundimonas diminuta: Implications for Membrane Microfiltration
TL;DR: A 2:1 molar ratio preparation of bismuth with a lipophilic dithiol significantly reduced extracellular polymeric substances (EPS) expression by Brevundimonas diminuta in suspended cultures at levels just below the minimum inhibitory concentration (MIC).
Journal ArticleDOI
The formation of Sr silicates at low temperature and the solubility product of tobermorite-like Sr5Si6O16(OH)2.5H2O
TL;DR: The Formation of Strontium Silicates at Low Temperature and the Solubility Product of Tobermorite like Sr5Si6O16(OH)2 5H20 as mentioned in this paper.
Proceedings ArticleDOI
Variation of Oxygen-to-Carbon Ratio in Oxyacetylene Flame
TL;DR: In this article, micro-structural and surface analysis of carbon soot using variation in C2H2 to O2 ratio in oxyacetylene flame torch is presented, and preliminary analysis indicate that at higher oxygen content, formation of SiO2 nanotubes and amorphous-SiC like structure take place while at higher C 2H2 flame content, the majority of carbon carbon with an evidence of some sp3 hybridization.
