Due to the continuous depletion of natural resources currently used for electricity generation, it is imperative to develop alternative energy sources. Human waste is nowadays being explored as an efficient source to produce bio-energy. Human waste is renewable and can be used as a source for an uninterrupted energy supply in bioelectricity or biofuel.

Oxygen consumption of the low/uncontaminated soils ranged between 7.

Optimizing of operational variables such as FeSO and HO doses was achieved by the response surface method (RSM). Statistical analysis led to the conclusion that FeSO is the more important than HO in the removal of TOC.
View Article and Find Full Text PDFA new direct contact assessment of soil toxicity using sulfur oxidizing bacteria (SOB) is proposed for analyzing the toxicity of soils. The proposed method is based on the ability of SOB to oxidize elemental sulfur to sulfuric acid in the presence of oxygen. Since sulfate ions are produced from sulfur by SOB oxidation activity, changes in electrical conductivity (EC) serve as a proxy to assess toxicity in water.
