Biotechnological potential of exopolysaccharide as a bioemulsifier produced by Rhizobium radiobacter CAS isolated from curd

Publication date: Available online 11 October 2019Source: Bioactive Carbohydrates and Dietary FibreAuthor(s): Digambar Kavitake, Farhat Zakirhusain Marchawala, Cedric Delattre, Prathapkumar Halady Shetty, Hilor Pathak, Prasad AndhareAbstractSuccinoglycan exopolysaccharide (EPS) from Rhizobium radiobacter CAS and its rheological behavior has been studied earlier. In present investigation the emulsifying potential of CAS EPS has been determined. CAS EPS concentration was optimized with hydrocarbons soybean oil and n-Hexane, whereas effect of pH (3.0–11.0), salinity, monovalent ions, divalent ion, (NaCl, KCl and MgCl2), freezing/thawing, temperature heating, emulsion stability and rheology on emulsifying activity (EA) was inspected using n-Hexane, paraffin oil, groundnut oil and soybean oil. CAS biopolymer represented superior emulsion stabilization ability (100%) under stress conditions and was highly tolerant to extreme pH, inorganic salts concentrations. Thermal stability of emulsions has found 100% at −20 °C–40 °C, whereas, at temperature 50 °C–120 °C high emulsion index (82.4–94.1% respectively) were recorded. Wetting filter paper test verified oil-in-water (o/w) type emulsion whereas rheological property showed pseudoplastic nature of emulsions. During stability of emulsions up to 30 days, some reduction of emulsification activity was observed for paraffin oil, however CAS hydrocolloid formed 100% emulsion index for n-H...

Abstract Herein, through a facile and energy-friendly approach, thermally stable manganese-derived amorphous stacked nanosheet (MASNS) coatings with controlled wetting property ranging from superhydrophilicity to superhydrophobicity were synthesized. The superhydrophobic MASNS coating exhibited remarkable selectivity and sensitivity in the solid phase microextraction (SPME) of non-polar aromatic analytes, even amid the abundance of polar compounds, due to the superhydrophobic effect and the stacked lamellar structures. The established method was applied to the determination of polycyclic aromatic hydrocarbons (PAH...

AbstractProphylactic treatment with aprotinin, a haemostatic antifibrinolytic agent, is indicated to reduce blood loss and blood transfusion in adults with a high risk of major bleeding undergoing primary or repeat isolated coronary artery bypass graft (CABG) with cardiopulmonary bypass. Overall, aprotinin was consistently more effective than tranexamic acid, ε-aminocaproic acid, desmopressin and placebo in reducing massive blood loss, the need for transfusions of blood products, and the need for reoperation due to diffuse bleeding in trials in this patient population, and was generally well-tolerated. The app...

In this study, a sessile drop technique was used to investigate the wetting and corrosion behavior of Al2O3 substrate against SiO2–MgO–FeO–CaO–Al2O3 slag, whose composition was determined according to the slag obtained from smelting nickel laterite in the RHF process. The experimental results showed that the slags with basicity ((MgO + CaO)/SiO2) of 0.43 and 0.63 had a low apparent contact angle of approximately 25° and 30°, respectively. It indicated the slag samples could wet well on the Al2O3 substrate. The spreading of slag on the substrate was mainly ascribed to the decrease o...

PI-based materials can also be converted to carbon materials by high temperature carbonization processes. The fabrication and properties of PI-based nanomaterials and corresponding carbon nanomaterials, however, have been less investigated, especially the packing behaviors of the polymer chains. In this work, we study the fabrication and c...

AbstractPurpose of ReviewNocturia is defined as awakening due to the desire to void during a period of intended sleep. The pathophysiology of nocturia is multifactorial and management remains a challenge. Herein, we provide an overview of the management strategies for nocturia and summarize the existing evidence for treatment of nocturia across the condition ’s broad etiologic categories: nocturnal polyuria, diminished bladder capacity, and global polyuria.Recent FindingsTreatment should begin with behavioral modification. A high level of evidence supports the efficacy of desmopressin in the treatment of nocturnal po...

Discussion Enuresis is a multifactorial disease that can lead to a diversity of problems for the child and family. Children presenting with Enuresis require careful evaluation and treatment to avoid future psychological and behavioral problems. The panel addressed recommendations on up to date choice of diagnosis evaluation and therapies.
