“…The bioaccumulation quantity (BAQ) is the mass of heavy metal uptake by biomass per unit mass. It is expressed as the difference between the heavy metal content in the whole plant or a certain plant organ, per unit mass, before and after the experiment [ 46 ]. In this study, the BAQ was calculated in mg/kg using the heavy metal content in the whole Eichhornia crassipes plant or a certain Eichhornia crassipes organ on day 0 and day 24 in the single component experiment.…”

This study experimentally investigated heavy metal removal and accumulation in the aquatic plant Eichhornia crassipes. Pb, Zn, Cd, and Mn concentrations, plant morphology, and plant functional groups were analyzed. Eichhornia crassipes achieved high removal efficiency of Pb and Mn from karst water (over 79.5%), with high proportion of Pb, Zn, and Cd absorption occurring in the first eight days. The highest removal efficiencies were obtained at initial Pb, Zn, Cd, and Mn concentrations of 1 mg/L, 2 mg/L, 0.02 mg/L, and 0.2 mg/L, respectively. Eichhornia crassipes exhibited a high bioconcentration factor (Mn = 199,567 > Pb = 19,605 > Cd = 3403 > Zn = 1913) and a low translocation factor (<1). The roots accumulated more Pb, Zn, Cd, and Mn than the stolons and leaves due to the stronger tolerance of roots. The voids, stomas, air chambers, and airways promoted this accumulation. Pb, Cd, Zn, and Mn likely exchanged with Mg, Na, and K through the cation exchange. C≡C, C=O, SO42−, O-H, C-H, and C-O played different roles during uptake, which led to different removal and accumulation effects.

“…49 The peak at 1452.38-1453.01 cm À1 originated from the stretching vibration of -CH in aliphatics, while the band at 1398.17-1403.90 cm À1 was assigned to the stretching vibration of C]O in the carboxyl group. 22,23 The peak at 1242.53-1251.27 cm À1 was associated with the stretching vibration of P]O and the band at 1038.06-1079.71 cm À1 was assigned to the stretching vibration of C-O-C in uronic acid. 22,23 Thereaer, these functional groups, such as hydroxyl, carboxyl, methyl, and aldehyde groups on cell wall or EPS that involved in the removal of cadmium by complexation with them.…”

“…Notably, a recent proteome-level investigation in Pseudomonas aeruginosa revealed that one third of the total upregulated proteins in cadmium amended culture are metalloproteins, suggesting their role in cadmium resistance (Izrael-Živković et al, 2018). Another separate proteomics-based study conducted by Zhang et al (2019) shows that upregulation of Cd 2+ /Zn 2+ exporting ATPase, type-VI protein secretion system, and glutathione-S-transferase under cadmium stress, which might be responsible for cadmium homeostasis in Burkhoderia cepacia strain GYP1 (Zhang et al, 2019). In this connection, a recent comparative transcriptome analysis by Wang H. et al (2020) revealed a unique strategy: using montmorillonite(Mt) for enhanced cadmium tolerance in Chryseobacterium sp.…”

Over the past few decades, the massive increase in anthropogenic activity and industrialization processes has increased new pollutants in the environment. The effects of such toxic components (heavy metals, pesticides, etc.) in our ecosystem vary significantly and are of significant public health and economic concern. Because of this, environmental consciousness is increasing amongst consumers and industrialists, and legal constraints on emissions are becoming progressively stricter; for the ultimate aim is to achieve cost-effective emission control. Fortunately, certain taxonomically and phylogenetically diverse microorganisms (e.g., sulfur oxidizing/reducing bacteria) are endowed with the capability to remediate such undesired components from diverse habitats and have diverse plant-growth-promoting abilities (auxin and siderophore production, phosphate solubilization, etc.). However, the quirk of fate for pollutant and plant-growth-promoting microbiome research is that, even with an early start, genetic knowledge on these systems is still considered to be in its infancy due to the unavailability of in-depth functional genomics and population dynamics data from various ecosystems. This knowledge gap can be breached if we have adequate information concerning their genetic make-up, so that we can use them in a targeted manner or with considerable operational flexibility in the agricultural sector. Amended understanding regarding the genetic basis of potential microbes involved in such processes has led to the establishment of novel or advanced bioremediation technologies (such as the detoxification efficiency of heavy metals), which will further our understanding of the genomic/genetic landscape in these potential organisms. Our review aimed to unravel the hidden genomic basis and eco-physiological properties of such potent bacteria and their interaction with plants from various ecosystems.
