phenol and its homologues are aromatics containing hydroxyl, methyl, amide and sulphonic groups attached to the benzene ring. these molecules are both anthropogenic and xenobiotics. phenols are environmental pollutants discharged through wastewaters from various industries. phenols are toxic to several biochemical reactions. however biological transformation of phenols to non-toxic entities exi...

More than 30 mineral elements have been found with different key functions in helping plants and animals to survive and live healthy. As a direct result, they have always attracted the attention of scientists. The quest is to find some efficient analytical and quantitative procedures in this study to determine some mineral and trace elements of Iranian Crocus sativus L. corms. Several studies h...

Riboflavin production in a culture of Ashbya gossypii was enhanced by adding mineral support with adsorbed soybean oil. When the support in an amount of 1 % to the amount of medium was added into the culture at agitation intensity corresponding to impeller rotation rate of 600 rpm, the attained riboflavin concentration was 2.5 g/L at the culture time of 4 days, i.e. 1.6 times higher than that i...

INTRODUCTION A sufficient intake of calcium enables correct bone mineralization. The bioavailability of calcium in water is similar to that in milk. OBJECTIVE To determine the concentration of calcium in public drinking water and bottled mineral water. METHODS We used ion chromatography to analyse the calcium concentrations of public drinking waters in a representative sample of 108 Spanish...

a number of researches have been performed in the field of elemental analysis of fruitsfrom different areas of iran and there is a vast unstudied area in this field. in this study, seven mineral elements such as na, k, ca, mg, fe, zn and cu in the tree soil, citrus limunum juice of gorgan and iranshahr gardens and citrus limetta juice of gorgan and bandarabas gardens were determined by flame ph...
