The field experiment was conducted at ICAR- National Institute on Abiotech Stress Management, Baramati to study the effect of different sources and levels sulphur soil nutrient availability, yield, quality uptake bellary onion. consists 14 treatments replicated thrice in randomized block design. treatment combinations viz: elemental sulphur, potassium schoenite ammonium sulphate three @ 30, 45 ...

The obligately autotrophic acidophile Thiobacillus ferrooxidans was grown on elemental sulfur in anaerobic batch cultures, using ferric iron as an electron acceptor. During anaerobic growth, ferric iron present in the growth media was quantitatively reduced to ferrous iron. The doubling time in anaerobic cultures was approximately 24 h. Anaerobic growth did not occur in the absence of elemental...

Cellular protein, pH, dissolved oxygen concentration, and static surface tension were measured during growth of Thiobacillus acidophilus on elemental sulfur in the absence and presence of up to 5,000 mg of Tween 80 per liter. The decrease in pH and the increase in sulfate production were observed to be less accurate measurements of growth when compared with the increase in cellular protein. The...

The effect of microbial and chemical corrosion on concrete structures operated in the conditions enterprises has been established that makes it possible to reliably predict timing their decommissioning order prevent industrial disasters. Even though construction complies with all building codes, eventually undergo biological corrosion. innovation proposed this study implies investigating depth ...
