Exo-polysaccharides like dextran produced by Weissella sp. have a wide range of applications in the food, pharmaceutical and other industries. This biopolymer and its derivatives like iron dextran, clinical dextran are rapidly emerging as a new and industrially important products. Dextran a polymer of glucose is produced using sucrose rich media with nitrogen source. It also requires efficient ...

Ultrasonic velocities and densities have been measured for the aqueous solution of manganese sulphate, nickel sulphate and copper sulphate in polyvinyl alcohol solution, in different concentration at 303K. Adiabatic compressibility, intermolecular free length, acoustic impedance, surface tension and other acoustical parameters have been calculated to assess the polymer-ion interaction. It is se...

A&met-Non-stoichiometric manganese dioxide prepared electrochemically at room temperature and suspended in dilute sulphuric acid is used to oxidise isosafrole to piperonal in 54% isolated yield. The manganese dioxide-manganese@) sulphate system can be recycled electrochemically at high current density. It has the further advantage that water-soluble materials derived from the chemical oxidation...

A pot experiment was conducted based on a factorial study and complete random block design with three replicates to investigate the phytoremediation potential of Sorghum biocilor L. in soils polluted with nickel and manganese during 2017-2018. The first factor was nickel nitrate (0, 60, and 120 mg kg-1 soil) and the second factor comprised of manganese sulphate (0, 50, and 100 µM). The characte...

The color of dye aqueous solution which cannot be removed by coagulation was selected to decolourize it through adsorption process using novel adsorbents namely Flocs Ferric Sulphate, Aluminium sulphate and Manganese sulphate. In order know efficacy adsorbents, batch sorption studies equilibrium were conducted. Good removal achieved with at pH::4 Sulphate pH::10, will applicable reduce the indu...

in order to study the effects of manganese sulfate in increasing seed yield of four safflower genotypes (carthamus tinctorius) under rainfed conditions, this experiment carried out in maragheh agricultural research station. the experiment was arranged with four mn fertilizer levels (0,10,20,30 kg ha-1) as soil application together with two foliar spray levels (1% and 2%) of 1.5 kg ha-1 manganes...

In human hepatoma HepG2 cell line curdlan sulphate enhances basal and interleukin-6-stimulated fibrinogen and antichymotrypsin (ACT) synthesis, slightly increases basal ceruloplasmin production and exerts only minor effects on alpha-1-proteinase inhibitor and transferrin. Curdlan sulphate may, at least in part, affect protein synthesis at a pretranslational level, as the expression of ACT mRNA ...

Manganese oxidizing bacteria colonizing the titanium surfaces exposed to seawater were characterized by periodically retrieving the coupons over a period of two years. About 20% of the initial colonizers were capable of oxidizing manganese, and the dominant manganese oxidizing bacteria were those belonging to Gram negative Pseudomonas spp. Gram positive, Bacillus spp, were also observed, though...
