Biological Removal of Dibenzothiophene from Soil and Changes to soil Sulfate by White-Rot Fungus Phanerochaete chrysosporium
This study investigated biodegradation of dibenzothiophene (DBT) in marsh soil spiked bywhite-rot fungus Phanerochaete chrysosporium. Soil samples were spiked with 100 ppm DBTand incubated at 30°C in a dark chamber for 30 days. Samples were evaluated for pH, Mnperoxidaseactivity, sulfate ion concentration and growth during the tests. Results showedmaximum levels of pH, Mn-peroxidase and sulfate...
متن کامل34S/32S fractionation in sulfur cycles catalyzed by anaerobic bacteria.
Stable isotopic distributions in the sulfur cycle were studied with pure and mixed cultures of the anaerobic bacteria, Chlorobium vibrioforme and Desulfovibrio vulgaris. D. vulgaris and C. vibrioforme can catalyze three reactions constituting a complete anaerobic sulfur cycle: reduction of sulfate to sulfide (D. vulgaris), oxidation of sulfide to elemental sulfur (C. vibrioforme), and oxidati...

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
15 صفحه اولNitrogen fertilization of coffee: organic compost and Crotalaria juncea L
A resposta do cafeeiro aos adubos orgânicos é pouco estudada e, por isso, objetivou-se, neste trabalho, avaliar o efeito de diferentes doses de composto e de Crotalaria juncea L. sobre o crescimento, a produção e a nutrição nitrogenada dos cafeeiros. Os tratamentos foram: composto orgânico, nas doses de 25, 50, 75 e 100% da adubação recomendada, com ou sem a parte aérea de C. juncea. A C. junce...
متن کاملMicrobial production of succinic acid using crude and purified glycerol from a Crotalaria juncea based biorefinery
Microbial conversion of crude and purified glycerol obtained in the process of biorefining Crotalaria juncea is carried out to produce succinic acid using Escherichia coli. Batch tests are performed for nine different substrate concentrations of commercial, purified and crude glycerol, in order to observe cell growth and substrate utilization rate. Inhibitory (Halden-Andrew, Aiba-Edward, Tessie...
