Yeasts can be enriched with microelements, including iron; however, special physicochemical conditions are required to formulate a culture media that promotes both yeast growth and iron uptake. Different iron sources do not affect biomass formation; however, considering efficacy, cost, stability, and compatibility with Saccharomyces cerevisiae metabolism, ferrous sulphate is recommended.

Histopathological effect of acute concentrations of heavy metals such as copper, ferroussulphate were studied. Results revealed extensive histopathological abnormalities in the internal structure of gill and brain of Catlacatla exposed to copper and ferrous sulphate in contrast to that of control fish, showing the severity of heavy metal toxicity.

S U M M A R Y : Desulphowifio desulphuricans (strain El Agheila Z) oxidized malate, fumarate, succinate, lactate and pyruvate quantitatively to acetate in cultures containing excess sulphate. Polysaccharide accumulated in old cultures. Cell suspensions harvested from malate media yielded theoretical amounts of sulphide and CO, from malate, fumarate or succinate + excess sulphate. Succinate was ...

The paper presents the investigations on absorbability of ferri/ferrous impurities found in commercial grade sodium sulphide. The later product is unsuitable for the manufacture of pharmaceutical grade chemicals and dyes chemicals.The author have carried out experiments on the use of precipated barium sulphate as an adsorbent in different propotions in the aqueous solution of commercial grade s...

Indonesia is among the largest countries in global rice production. Annual generation of straw about 20 million tons were reported. It therefore, utilization as natural dye considered to minimize pollutant problem. Rice composed 48.7% carbon that generate black color. In this research, dyes ash applied cotton and rayon fabrics, followed by mordanting using lime, alum, ferrous sulphate. The colo...

BACKGROUND Preliminary clinical evidence suggests that heme iron polypeptide (HIP) might represent a promising, novel oral iron supplementation strategy in chronic kidney disease. The aim of this multi-centre randomized controlled trial was to determine the ability of HIP administration to augment iron stores in darbepoetin (DPO)-treated patients compared with conventional oral iron supplementa...

Abstract Magnetic Fe 3 O 4 nanoparticles (NPs) were successfully synthesized via co-precipitation method using ferric chloride and ferrous sulphate as the starting materials. The shape size of NPs controlled by different types additive including ammonium hydroxide sodium hydroxide. results revealed that adding hydroxide, particles attained a spherical with uniform size. On other hand, turned fr...

This study relates to a method for evaluating the degradation efficiency of Ascaris lumbricoides eggs through a Fenton reaction, using hydrogen peroxide (H2O2) at 100, 250, and 500 mg/L, ferrous sulfate (FeSO4) at 458 mg/L Fe(2+) and pH values of 3, 4.5, and 6. The experiments were conducted according to a 3(2) experimental design, with 1:1, 3:1, and 5:1 (H2O2/Fe(2+)) molar ratios. The oxidatio...
