A range of some Iranian monofloral honeys were assayed for antibacterial activity with and without hydrogen peroxide which is inactivated by the addition of catalase. I t was found that the high amount of antibacterial activity in honeys was due to a factor other than hydrogen peroxide. The test microorganism Staphylococcus aureus, was not inhibited by the acidity or the osmolarity of the h...

Drought is one of the major factors limiting crop production in Iran. Twenty Iranian wheat cultivars with wide range of sensitivity to drought, including 18 varieties of bread wheat and two varieties of durum wheat were used in two separate field experiments in 2009-2010 at the Experimental Station of College of Agricultural in Shiraz University. Each experiment was conducted as a randomized co...

Background and Objective: The percence of organic compounds resistant to biodegradation has become one of the most important environmental challenges in the chemical and petrochemical industry in this century. Phenol or hydroxyl benzene as an aromatic hydrocarbon discharged into the environment through certian industrial effluents which, thereby, pollutes water resources. This study examined th...

In concentration of hydrogen peroxide, first, the solution should be quite pure, and then, it concentrate with methods such as vacuum distillation and cooling crystallization, because impurities in the hydrogen peroxide solution in high concentrations are causing decomposition of this substance; that is very dangerous. The purpose of this article is separation of chromium and magne...

The production of reactive oxygen species occurs during the natural metabolism of oxidative-breathing cells. Among reactive oxygen species, hydrogen peroxide is more dangerous to cell life due to its long half-life, but it is meanwhile an important regulatory molecule in redox signaling in living things. Peroxidases are one of the key antioxidant enzymes that are widely distributed in nature an...

In this work, we described a cost-effective and environmentally friendly technique for green synthesis of colloidal silver nanoparticles from aqueous extract of fresh leaves of Acacia melanoxylon and its application as a dopamine and hydrogen peroxide sensor. The prepared silver nanoparticles were characterized by UV-Visible absorption spectroscopy, X-ray diffraction (XRD), scanning electron mi...

Background and purpose: Amoxicillin is one of the antibiotics that has received especial attention as it causes resistance in bacteria. This compound enters the aquatic environment through different routes including human and animal waste, sewage, and waste disposal of medical health centers, veterinary and pharmaceutical industries. The aim of this study was to remove amoxicillin from aqueous ...

One of the major abiotic stresses limiting the productivity and the geographical distribution of many important crops is low temperature. Hydrogen sulfide (H2S) is an important signaling molecule involved in several stress-resistance processes such as drought, salinity and heavy metal stresses in plants. The aim of this study was to investigate the effects of exogenous H2S...
