Bacterial bioabsorption of nickel from industrial cooling water 总被引:1,自引:0,他引:1
Three bacterial strains tolerant to the presence of 100 mg litre(-1) nickel ions were isolated from a water reclamation system. Each organism was tested for ability to accumulate nickel at the above-mentioned concentration. The organism capable of maximum nickel accumulation was identified as an Enterobacter sp. and intracellular nickel deposition by this microorganism was determined using energy dispersive X-ray analysis (EDAX) and transmission electron microscopy. A metal-staining technique for light microscopy was developed. Further studies revealed that growth and glucose utilisation by this isolate was inhibited in culture by nickel. 相似文献

Community‐based water supply (CBWS) is an example of how a community manages common pool resources (CPR). This results in an alternative approach to solve water supply problems in developing countries by enhancing community participation in managing water supply. This research evaluates the sustainability of five CBWS projects in Cikarang, Indonesia by using Ostrom's design principles, with additional sustainability factors found in the Sustainable Development Goal (SDG) on drinking water and groundwater sustainability. Quinn et al. (2007) criteria were used in the analysis, and the results show that the management of four CBWS institutions were absent and one CBWS institution was weak. With regards to the SDG's drinking water target, the CBWS institutions were unable to comply with safe water standards, and in terms of groundwater sustainability, efforts to monitor and sustain groundwater tables were absent. Results from this research suggest that more focus must be placed on water quality and groundwater sustainability for CBWS projects. 相似文献
