“…As described above, this effect may be due to the provision of organic carbon, as is suggested by the simultaneous increase in the activity of dehydrogenase, a parameter generally indicative of biological oxidation of organic compounds (Alguacil et al, 2012;Elifantz et al, 2011;Frenk et al, 2014;Friedel et al, 2000) (Table 2). Through the supplying of organic matter and nutrients, soil irrigation with wastewater is expected to stimulate different organisms and metabolic pathways.…”

“…The increase in the activity of some enzymes (e.g. hydrolytic, proteolytic, laccases, cellulases, phosphatase) has been reported in soils irrigated with treated wastewater (Adrover et al, 2012;Alguacil et al, 2012;Chevremont et al, 2013;Elifantz et al, 2011;Frenk et al, 2014;Friedel et al, 2000;Meli et al, 2002;Morugán-Coronado et al, 2013). It is, thus, suggested that wastewater irrigation may stimulate the activity of microorganisms involved in the biochemical balance of elements such as C, N and P. In addition, organic matter may stabilize the enzymes, which remain active in the ex-tracellular medium, independently of the soil microbial (Trasar-Cepeda et al, 2008a).…”

“…The influence of organic matter supply on the microbiota is suggested by the fact that wastewater irrigation was sometimes associated with an increase in soil microbial biomass and in soil enzyme activities (Table 4). Examples are the activities of enzymes such as dehydrogenase, laccase, cellulase, protease and urease (Chevremont et al, 2013;Friedel et al, 2000;Liu and Haynes, 2011;Morugán-Coronado et al, 2013). These effects are probably due to the stimulation of microbial growth and activity, boosted by the organic matter and nutrients supplied by wastewater (Adrover et al, 2012;Chevremont et al, 2013;Friedel et al, 2000;Liu and Haynes, 2011;Morugán-Coronado et al, 2013;Tam, 1998).…”

“…However, the addition of ammonium nitrate to soils was shown to in-crease the bacterial richness (Turlapati et al, 2013). Friedel et al (2000) studying a soil irrigated with wastewater for more than 18 years demonstrated that denitrifying activity was stimulated comparing to those under rainfed agriculture. This difference was probably due to the availability of NO3-N released as product of the activity ammonia and nitrite-oxidizing bacterial groups.…”

The reuse of treated wastewater, in particular for irrigation, is an increasingly common practice, encouraged by governments and official entities worldwide. Irrigation with wastewater may have implications at two different levels: alter the physicochemical and microbiological properties of the soil and/or introduce and contribute to the accumulation of chemical and biological contaminants in soil. The first may affect soil productivity and fertility; the second may pose serious risks to the human and environmental health. The sustainable wastewater reuse in agriculture should prevent both types of effects, requiring a holistic and integrated risk assessment. In this article we critically review possible effects of irrigation with treated wastewater, with special emphasis on soil microbiota. The maintenance of a rich and diversified autochthonous soil microbiota and the use of treated wastewater with minimal levels of potential soil contaminants are proposed as sine qua non conditions to achieve a sustainable wastewater reuse for irrigation.

“…Irrigation with WW and RW could result in the shift of soil basic characteristics that could influence microbial diversities and functions (Friedel et al 2000;Mapanda et al 2005;Qian and Mecham 2005). Previous studies have shown that WW irrigation could increase the rates of denitrification and denitrifying enzyme synthesis in a soil ecosystem (Barton et al 1999(Barton et al , 2000Friedel et al 2000;Zou et al 2009). However, the responses of soil functional genes involved in denitrification to wastewater irrigation still remain unknown.…”

Purpose Denitrification is an important biochemical process in global nitrogen cycle, with a potent greenhouse gas product N 2 O. Wastewater irrigation can result in the changes of soil properties and microbial communities of agricultural soils. The purpose of this study was to examine how the soil denitrification genes responded to different irrigation regimes. Materials and methods Soil samples were collected from three rural districts of Beijing (China) with three different irrigation regimes: clean groundwater (CW), reclaimed water (RW), and wastewater (WW). The abundance and diversity of three denitrification microbial genes (nirS, nirK, and nosZ) were examined by real-time polymerase chain reaction (PCR) and denaturing gradient gel electrophoresis (DGGE) molecular approaches. Results and discussion The abundance of nirS in the WW treatment was higher than that in the CW treatment, and no significant difference was found between the RW and CW or WW treatments. The abundance of nirK gene of the RW and WW treatments was higher than that of the CW treatment. There was no difference for nosZ gene among the three treatments. Correspondence analysis based on the DGGE profiles showed that there was no obvious difference in the nosZ gene composition, but nirS and nirK genes changed with different irrigation regimes. Conclusions Irrigation with unclean water sources enhanced the soil NO 3 − content and changed the abundance and composition of soil denitrifiers, and different functional genes had different responses. Irrigation with unclean water sources increased the abundance of nirK gene and changed the community structures of nirS and nirK genes, while nosZ gene was relatively stable in the soil. These results could be helpful to explore the mechanisms of the variation of denitrification processes under long-term wastewater irrigation and partially explain the reason of more N 2 O output in the field with wastewater irrigation.
