“…Aspergillus is the most common occurring genera in sewage sludge (More et al 2010). As a result, it has been extensively reported to have potential for heavy metal biosorption (Srivastava and Majumder 2008;Srivastava and Thakur 2006;Zafar et al 2007), biosorption of reactive dye from textile wastewater (Khalaf 2008), and biodegradation and detoxification of industrial wastewaters (Fadil et al 2003). Antagonistic Trichoderma are frequently found in soils in temperate regions and have been found with the pronounced ability to secrete diverse category of enzymes such as peroxidase, laccases, and oxidases which are responsible for the biodegradation of toxic organic compounds like polycyclic aromatic hydrocarbon (PAH) (Wang et al 2006), anthracene, and fluoranthene in treatment wetlands (Giraud et al 2001).…”

A 454 high-throughput pyrosequencing approach was used to characterize the structures of microbial communities in wetland mesocosms receiving caffeine-enriched wastewater at a concentration of 250 μg L −1. The removal efficiencies of caffeine in the planted beds (93.0 %) were significantly (p < 0.05) higher than those in the unplanted beds (81.4 %). Bacterial diversity was decreased by 25 and 22.4 %, respectively, in both planted and unplanted mesocosms after 210-day operation. The results of taxonomic analyses suggested that chronic exposure of wetland ecosystems to caffeine could lead to moderate shifts in microbial community composition. In total, 2156 operational taxonomic units (OTUs) were generated and 20 phyla comprising 260 genera were identified. The major phylogenetic groups at phylum level included Firmicutes (39 %), Actinobacteria (25.1 %), Proteobacteria (17.1 %), Synergistetes (5.6 %), and Chloroflexi (5.5 %).Bacilli and Synergistia increased in abundance in the planted mesocosms, while for the unplanted mesocosms, Actinobacterial, Clostridia and Betaproteobacteria exhibited increased proportion under the exposure of caffeine. At genus level, Propionibacterium, Staphylococcus, Bacillus, and Streptococcus were found to be increased in abundance after caffeine treatment. As for the response of fungal community to caffeine enrichment, genus like Cladosporium, Emericellopsis, Aspergillus, and Phoma were found to be resistant to caffeine disturbance. When compared to the microbial community between planted and unplanted mesocosms, a distinct community profile for both bacteria and fungi community was observed. The presence of plants had a remarkable effect on the structure of microbial community, helping buffer against the stress associated with caffeine exposure.

“…Due to the environmental and health risks created by Lead and Cadmium, the removal of these heavy metals from water and wastewater is essential. In this regard, several methods including chemical precipitation, ion exchange, electrochemical treatment, membrane separation, solvent extraction and adsorption have been applied 12- 13 . The adsorption method has been shown to be effective in the removal of heavy metals from aqueous solution8.…”

The adsorption behavior of Pb(II) and Cd(II) ions in aqueous solutions on silica aerogels modifi ed with amino propyl triethoxysilane was investigated as a function of pH, contact time, adsorbate concentration and adsorbent dose. It was found that maximum adsorption of Pb(II) and Cd(II) ions occurs at pH 6.0 and pH 8.0, respectively. The optimum contact time to obtain equilibrium adsorption with the modifi ed silica aerogel was experimentally found to be around 48h. Adsorption isotherms clearly indicated that the adsorption behavior of metals ions on the modifi ed silica aerogels is fi tted well with both the Langmuir and Freundlich isotherms. The maximum adsorption capacities of Pb(II) and Cd(II) on modifi ed silica aerogel were found to be 45.45mg/g and 35.71mg/g, respectively. The results indicated that silica aerogels modifi ed with amino functional groups can be used as an effi cient adsorbent in the removal of metal ions such as Pb(II) and Cd(II) from aqueous solutions.
