“…To improve the overall potential of plant-based phytoremediation, the combined use of plants and bacteria has been recently proposed which can significantly enhance the degradation of organic pollutants including POPs in planta as well as ex planta (Afzal et al 2014b;Glick 2010;Khan et al 2013a;Mitter et al 2013). The following sections elucidate the importance of plant-bacteria partnerships for the remediation of POPs-contaminated environment.…”

High toxicity, bioaccumulation factor and widespread dispersal of persistent organic pollutants (POPs) cause environmental and human health hazards. The combined use of plants and bacteria is a promising approach for the remediation of soil and water contaminated with POPs. Plants provide residency and nutrients to their associated rhizosphere and endophytic bacteria. In return, the bacteria support plant growth by the degradation and detoxification of POPs. Moreover, they improve plant growth and health due to their innate plant growth-promoting mechanisms. This review provides a critical view of factors that affect absorption and translocation of POPs in plants and the limitations that plant have to deal with during the remediation of POPs. Moreover, the synergistic effects of plant-bacteria interactions in the phytoremediation of organic pollutants with special reference to POPs are discussed.

“…Rhizobacteria have been investigated for their plant growth-promoting capacity and in the last decade the use of such bacteria to enhance phytoremediation efficiency has been reported (He et al, 2005;Liste and Prutz, 2006;Biryukova et al, 2007;Gerhardt et al, 2009). Endophytic bacteria have also received considerable attention as many of them have an intimate relationship with the plant and are prominent plant growth promoters (Ryan et al, 2008;Compant et al, 2010;Mitter et al, 2013a). However, the concept of using endophytic bacteria to improve phytoremediation efficiency has been proposed relatively recently (Andria et al, 2009;Weyens et al, 2009b;Yousaf et al, 2011;Andreolli et al, 2013).…”

“…These relationships are well characterized in the most important crop/microbe combinations in field (Hayat et al, 2010). PGPMs can promote plant growth and yield, directly or indirectly, through several mechanisms (Vessey, 2003; Mitter et al, 2013). Biological fixation of atmospheric N 2 , performed by specific strains of symbiotic Rhizobia bacteria in leguminous plants (Mylona et al, 1995), and non-symbiotic bacteria (e.g., Azotobacter spp., Pseudomonas spp.)…”

The use of hydroponic systems for cultivation in controlled climatic conditions and the selection of suitable genotypes for the specific environment help improving crop growth and yield. We hypothesized that plant performance in hydroponics could be further maximized by exploiting the action of plant growth-promoting organisms (PGPMs). However, the effects of PGPMs on plant physiology have been scarcely investigated in hydroponics. Within a series of experiments aimed to identify the best protocol for hydroponic cultivation of soybean [Glycine max (L.) Merr.], we evaluated the effects of a PGPMs mix, containing bacteria, yeasts, mycorrhiza and trichoderma beneficial species on leaf anatomy, photosynthetic activity and plant growth of soybean cv. ‘Pr91m10’ in closed nutrient film technique (NFT). Plants were grown in a growth chamber under semi-aseptic conditions and inoculated at seed, seedling and plant stages, and compared to non-inoculated (control) plants. Light and epi-fluorescence microscopy analyses showed that leaves of inoculated plants had higher density of smaller stomata (297 vs. 247 n/mm2), thicker palisade parenchyma (95.0 vs. 85.8 μm), and larger intercellular spaces in the mesophyll (57.5% vs. 52.2%), compared to non-inoculated plants. The modifications in leaf functional anatomical traits affected gas exchanges; in fact starting from the reproductive phase, the rate of leaf net photosynthesis (NP) was higher in inoculated compared to control plants (8.69 vs. 6.13 μmol CO2 m-2 s-1 at the beginning of flowering). These data are consistent with the better maximal PSII photochemical efficiency observed in inoculated plants (0.807 vs. 0.784 in control); conversely no difference in leaf chlorophyll content was found. The PGPM-induced changes in leaf structure and photosynthesis lead to an improvement of plant growth (+29.9% in plant leaf area) and seed yield (+36.9%) compared to control. Our results confirm that PGPMs may confer benefits in photosynthetic traits of soybean plants even in hydroponics (i.e., NFT), with positive effects on growth and seed production, prefiguring potential application of beneficial microorganisms in plant cultivation in hydroponics.
