“…Numerous workers have also reported similar results (Tunali et al 2006;Giotta et al 2011). The FTIR spectra of Cu free and Cu loaded biomass revealed a complex and additive influence of chemical structure of bacterial cell surface comprising different functional responsible for regulating the possible cell-cation interactions (Anand et al 2006). Plant growth-promoting characteristics of CRB15…”

Rhizobacteria may enhance biomass production and heavy metal tolerance of plants under stress conditions. The present study was carried out for isolation of metalresistant bacteria that can be further utilized for phytoremediation process. A potential metal-resistant strain CRB15 was isolated from rhizospheric region of Saccharum spontaneum that was found to be resistant against Cu (6.29 mM), Zn (3.25 mM), Pb (1.5 mM), Ni (1.25 mM), and Cd (0.25 mM). SEM analysis was performed for evaluation of morphological changes on bacterial isolate. FTIR analysis observed the change in wavenumbers after the addition of Cu. 16S rDNA sequence analysis showed that CRB15 isolate matched best with genus of Kocuria and was named as Kocuria sp. CRB15. The isolate Kocuria sp. CRB15 was a potential plant growth-promoting rhizobacterium as it had a high IAA (46 lg ml -1 ), P solubilisation (39.37 lg ml -1 ), ammonia production (30.46 lmol ml -1 ), and hydrogen cyanide production capacity. Root-shoot elongation assay conducted on Brassica nigra under lab conditions with strain CRB15 demonstrated positive effects of strain CRB15 in root and shoot elongation of Cu-treated seedlings. This study proved the Kocuria sp. CRB15 a potential PGPR for bacterialassisted phytoremediation.

“…Such microorganisms are an extremely versatile group that can adapt and grow in extreme conditions of pH, temperature, nutrient availability and high concentrations of metals (Anand et al 2006). Factors such as the interaction between metals and the microbial cell wall, periplasm, plasmatic membrane, cytoplasm are key for fungi adaptation in different environments (Cervantes et al 2006).…”

“…However, the mechanisms developed by fungi to grow and survive under hostile environments of high metal concentrations make them a focal point to be applied in the elimination of these pollutants. Additionally, filamentous fungi have been poorly studied, but some reports have indicated that they have a high tolerance to Cr(VI) and can colonise sites that are contaminated with this pollutant (Anand et al 2006).…”

Contamination by hexavalent chromium has had a large impact on modern society and human health. This problem is a consequence of its great industrial applicability to several products and processes. Short-term exposure to hexavalent chromium can cause irritation, ulceration in skin and stomach and in addition to cancer, dermatitis, and damage to liver, renal circulation and nervous tissues, with even death being observed in response to long-term exposures. Many techniques have been used for the remediation of this pollutant, including physical and chemical approaches and, in more recent years, biological methods. Filamentous fungi isolated from contaminated sites exhibit a significant tolerance to heavy metal; hence, they are an important source of microbiota capable of eliminating hexavalent chromium from the environment. However, these microorganisms can do so in different ways, including biosorption, bioreduction, and bioaccumulation, among others. In this review, we explore several of the most documented mechanisms that have been described for fungi/hexavalent chromium interactions and their potential use in bioremediation.

“…Trichoderma spp. have great role in ecology as they take part in decomposition of plant residues as well as biodegradation of man-made chemicals and bioaccumulation of high amount of different metals from waste water and soil (Ezzi and Lynch, 2005;Anand et al, 2006). Evidence suggested that Trichoderma spp.…”
