Assessment of temporal and spatial evolution of bacterial communities in a biological sand filter mesocosm treating winery wastewater
Ramond, Jean-Baptiste; Welz, P.J.; Tuffin, Marla; Burton, Stephanie G. (The Society for Applied Microbiology, 2013)AIMS: To assess the impact of winery wastewater (WW) on biological sand filter (BSF) bacterial community structures, and to evaluate whether BSFs can constitute alternative and valuable treatment-processes to remediate WW. ... -
Impact of metagenomic DNA extraction procedures on the identifiable endophytic bacterial diversity in Sorghum bicolor (L. Moench)
Maropola, Mapula Kgomotso Annah; Ramond, Jean-Baptiste; Trindade, Marla (Elsevier, 2015)Culture-independent studies rely on the quantity and quality of the extracted environmental metagenomic DNA (mDNA). To fully access the plant tissue microbiome, the extracted plant mDNA should allow optimal PCR applications ... -
Selection of Clostridium spp. in biological sand filters neutralizing synthetic acid mine drainage
Ramond, Jean-Baptiste; Welz, Pamela J.; Le Roes-Hill, Marilize; Tuffin, Marla I.; Burton, Stephanie G.; Cowan, Donald A. (Wiley, 2013)In this study, three biological sand filter (BSF) were contaminated with a synthetic iron- [1500 mg L-1 Fe(II), 500 mg L-1 Fe(III)] and sulphate-rich (6000 mg L-1 SO2/4-) acid mine drainage (AMD) (pH = 2), for 24 days, to ... -
Selection of diazotrophic bacterial communities in biological sand filter mesocosms used for the treatment of phenolic-laden wastewater
Ramond, Jean-Baptiste; Welz, Pamela J.; Tuffin, Marla I.; Burton, Stephanie G.; Cowan, Donald A. (Springer Verlag, 2013)Agri effluents such as winery or olive mill waste-waters are characterized by high phenolic concentrations. These compounds are highly toxic and generally refractory to biodegradation. Biological sand filters (BSFs) represent ...
