Acid sulfate soils

Bioremediation by Sulfate Reducing Bacteria of Acid Mine Drainage

Mining activity produces metal sulfide wastes particularly pyrite which remain in the mine long after operations cease. When water percolates through a mine where oxygen is present, a series of chemical reactions occur which produce extremely low pH and high concentrations of toxic sulfate and metal ions. This toxic leachate can cause severe aquatic habitat degradation downstream of the mine. T...

ویژگی های زمین شیمیایی، کانی شناسی، و میکرومورفولوژیکی خاک ها و سنگ مادر مربوطه در منطقه بین بخش های جنوبی زاگرس و خلیج فارس تا دریای عمان(استان هرمزگان، ایران) مورد بررسی قرار گرفت. هدف های این مطالعه شناسایی تغییرات در خصوصیات فیزیکی، شیمیایی، و ترکیب کانی شناسی خاک، مطالعه میکرومورفولوژی و تکامل خاک، و بررسی توزیع عنصر خاک بر اساس هوازدگی، پروسه های خاک و زمین شناسی جهت توصیف اثرات مواد مادر...

Metabolic Flexibility of Sulfate-Reducing Bacteria

Dissimilatory sulfate-reducing prokaryotes (SRB) are a very diverse group of anaerobic bacteria that are omnipresent in nature and play an imperative role in the global cycling of carbon and sulfur. In anoxic marine sediments sulfate reduction accounts for up to 50% of the entire organic mineralization in coastal and shelf ecosystems where sulfate diffuses several meters deep into the sediment....

Yeast sulfate-reducing system. I. Reduction of sulfate to sulfite.

X35-APS-This substrate was synthesized from S%ulfur trioxide-pyridine complex and AMP by a method similar to that of Baddiley et al. (13) except for simplifications and modifications necessary for introduction of label. An alternat,ive method has been described by Reichard and Ringertz (14). Approximately 3.7 me of S35-HzS04 was dried at 80” in a reaction tube fitted with a ball joint and side ...
