“…It is reported that poultry manure contains high nitrogen (Zagury et al 2006). Nitrogen contents in sheep manure, cow manure and poultry manure were reported to be 0.7-1.9 % (Gibert et al 2004;Waybrant et al 1998), 2-2.1 % (Choudhary and Sheoran 2011;Neculita et al 2011;Robinson-Lora and Brennan 2010) and 1.3-5.8 % (Neculita and Zagury 2008;Zagury et al 2006;Gibert et al 2004), respectively ( Table 3). The nitrogen in manure is mostly comprised of NH 4 ?…”

“…The column bioreactors treating AMD were packed with the various substrates that served both as nutrient source and attachment material for SRB biomass (Neculita et al 2011;Newcombe and Brennan 2010;McCauley et al 2009;Gibert et al 2004). From these studies, it is found that the individual organic substrates as discussed in this section could not act as an efficient nitrogen source for SRB.…”

“…These substrates vary in the nitrogen content, and exhibited differences in their ability to support SRB growth and sulfate reduction (Neculita et al 2011;Newcombe and Brennan 2010;McCauley et al 2009;Zagury et al 2006;Gibert et al 2004;Cocos et al 2002;Waybrant et al 1998). …”

“…Manure is reported to be mixed with different proportions of substrate mixtures in passive bioreactors treating AMD (Choudhary and Sheoran 2011;Neculita et al 2011;Robinson-Lora and Brennan 2010;Neculita and Zagury 2008;Zagury et al 2006;Gibert et al 2004). These substrate mixtures vary widely in the ability to support SRB growth and biological sulfate reduction depending on the composition (Table 3).…”

“…As a single substrate, only chitin and MWE were able to support highest biological sulfate reduction (Table 3). The combination of substrates such as compost, wood chips, urea and sawdust was reported to be highly effective (Neculita et al 2011;Neculita and Zagury 2008;Zagury et al 2006). Most of the experiments were conducted to find out their effectiveness as efficient carbon source while not considering the effect of nitrogen present in them.…”

Suitability of different growth substrates as source of nitrogen for sulfate reducing bacteria

Sulfate reducing bacteria (SRB) mediated treatment of acid mine drainage is considered as a globally accepted technology. However, inadequate information on the role of nitrogen source in the augmentation of SRB significantly affects the overall treatment process. Sustenance of SRB depends on suitable nitrogen source which is considered as an important nutrient. This review focuses on the different nitrogen rich growth substrates for their effectiveness to support SRB growth and sulfate reduction in passive bioreactors. Compounds like NH4Cl, NH4HCO3, NO3 (-), aniline, tri-nitrotoluene, cornsteep liquor, peptone, urea, and chitin are reported to have served as nitrogen source for SRB. In association with fermentative bacteria, SRB can metabolize these complex compounds to NH4 (+), amines, and amino acids. After incorporation into cells, these compounds take part in the biosynthesis of nucleic acids, amino acids and enzyme co-factor. This work describes the status of current and the probable directions of the future research.
