In order to evaluate the impact of reclaimed water on the ecology of bacterial communities in the Typha angustifolia L. rhizosphere soil, bacterial community structure was investigated using a combination of terminal restriction fragment length polymorphism and 16S rRNA gene clone library. The results revealed significant spatial variation of bacterial communities along the river from upstream and downstream. For example, a higher relative abundance of γ-Proteobacteria, Firmicutes, Chloroflexi and a lower proportion of β-Proteobacteria and ε-Proteobacteria was detected at the downstream site compared to the upstream site. Additionally, with an increase of the reclaimed water interference intensity, the rhizosphere bacterial community showed a decrease in taxon richness, evenness and diversity. The relative abundance of bacteria closely related to the resistant of heavy-metal was markedly increased, while the bacteria related for carbon/nitrogen/phosphorus/sulfur cycling wasn't strikingly changed. Besides that, the pathogenic bacteria markedly increased in the downstream rhizosphere soil since reclaimed water supplement, while the possible plant growth-promoting rhizobacteria obviously reduced in the downstream sediment.Together these data suggest cause and effect between reclaimed water input into the wetland, shift in bacterial communities through habitat change, and alteration of capacity for biogeochemical cycling of contaminants.

“…KC215462) had high similarity (99%) with two Desulfomicrobium species: D. baculatum and D. norvegicum (Table 2). These two sulfate-reducing bacteria are non-spore-forming, Gram-negative, obligately anaerobic rods (Azabou et al, 2007;Genthner et al, 1997). Isolate B1 cells were rod-shaped (0.5-1 mm ¥ 3-5 mm) with rounded ends and occurred singly or in pairs, motile and non-spore forming (Fig.…”

“…The clones obtained from the enrichments at neutral pH (Budel and Paques) exhibited high 16S rRNA sequence identity (99%) to two sulfate-reducing species: Desulfomicrobium baculatum and Desulfomicrobium norvegicum (Azabou et al, 2007;Genthner et al, 1997). D. baculatum differs from D. norvegicum by its chemoautotrophic growth on H 2 /CO 2 (Azabou et al, 2007). The genome from D. baculatum (DSM 4028) has a whole cluster of genes coding for enzymes involved in glycerol metabolism (Dbac_1434-Dbac_1446) (Copeland et al, 2009).…”

Phosphogypsum (PG) is an industrial waste composed mainly by sulphate, turning it a suitable sulphate source for sulphate-reducing bacteria (SRB). In the present work the capability of two SRB communities, one enriched from Portuguese PG (culture PG) and other from sludge from a wastewater treatment plant (culture WWT-1), to use sulphate from PG, was compared. In addition, the impact of this sulphate-rich waste in the microbial community was assessed. The highest efficiency in terms of sulphate reduction was observed with culture WWT-1. The bacterial composition of this culture was not significantly affected when sodium sulphate from the nutrient medium was replaced by PG as sulphate source. Next generation sequencing (NGS) showed that this community was phylogenetically diverse, composed by bacteria affiliated to Clostridium, Arcobacter and Sulfurospirillum genera and by SRB belonging to Desulfovibrio, Desulfomicrobium and Desulfobulbus genera. In contrast, the bacterial structure of the community enriched from PG was modified when sodium sulphate was replaced by PG as sulphate source. This culture, which showed the poorest performance in the use of sulphate from PG, was mainly composed by SRB related to Desulfosporosinus genus. The present work provides new information regarding the phylogenetic characterization of anaerobic bacterial communities with the ability to use PG as sulphate donor, thus contributing to improve the knowledge of microorganisms suitable to be used in PG bioremediation. Additionally, this paper demonstrates that an alternative to lactate and low-cost carbon source (wine wastes) can be used efficiently for that purpose.
