A pyrrhotite and sulfur-circulating packed bed reactor (PS-CPBR) was constructed to study the removal process mechanism of NO3−-N PO43−-P with different electron donors. The results showed that performance mixed donors (pyrrhotite sulfur) superior single donor (pyrrhotite). optimum conditions in PS-CPBR were a hydraulic retention time (HRT) 12 h C/N 0, average efficiency 100% 86.39%. sulfur abl...

The efficacy of 1-methylisatin 3-thiosemicarbazone for the inhibition of neurovaccinia virus in mice has been documented by D. J. Bauer and P. W. Sadler (Brit. J. Pharmacol. 15:101, 1960). The inhibition of adenovirus multiplication by this compound has been reported by D. J. Bauer and K. Apostolov (Science 154:796, 1966). The present communication pertains to the microbial conversion of 1-meth...

Gold is used in various fields and a rare resource nature. Recovery of gold from domestic wastes desired Japan. Bamboo an abundant biomass Japan, the promotion its utilization desired. In our previous studies, sulfur-impregnated carbonaceous adsorbent with high heavy metal removal has been prepared resources using sulfur affinity for metals. this study, bamboo was powder by pyrolyzing at 800°C ...

A heterotrophic Pseudomonas putida CH11 was isolated from livestock farming wastewater and applied for the treatment of H2S-containing gas. Extensive tests including removal characteristics, metabolic products, and removal efficiencies of H2S by P. putida CH11 were examined in batch and continuous systems. The optimum pH required to remove hydrogen sulfide was found in the range of 6-8. The max...

Syed, M., Soreanu, G., Falletta, P. and Béland M. 2006. Removal of hydrogen sulfide from gas streams using biological processes A review. Canadian Biosystems Engineering/Le génie des biosystèmes au Canada 48: 2.1 2.14. Hydrogen sulfide (H2S) is a toxic and odorous compound present in biogas produced by the anaerobic digestion of biosolids and other organic materials. Due to its corrosive nature...
