A total of 85 chromate-resistant bacteria were isolated from the rhizosphere of water hyacinth grown in Mariout Lake, Egypt, as well as the sediment and water of this habitat. Only 4 (11%), 2 (8%), and 2 (8%) of isolates from each of the environments, respectively, were able to tolerate 200 mg Cr (VI) L−1. When these eight isolates were tested for their ability to tolerate other metals or to reduce chromate, they were shown to also be resistant to Zn, Mn, and Pb, and to display different… 

Isolation and Identification of Nine Dichromate Cr + 6 resistance Bacteria by Modern Techniques

All bacterial species in this study were shown to have high resistance to potassium dichromate Cr 6+ , with Acinetobacter notherradio resistants leading, followed by AcinetOBacter ventianus, then comes Bacillus pumilus and B. cereus.

The role of bacteria on heavy-metal extraction and uptake by plants growing on multi-metal-contaminated soils

Results show that bacteria play an important role in increasing metal availability in soil, thus enhancing Cr, Pb, Zn and Cu accumulation by Z. mays and S. bicolor.

Eichhornia crassipes has a high tolerance to pollution, making it eligible for use in wastewater phytoremediation. This paper reports a laboratory study conducted under environmental conditions of

Phytoremediation potential of aquatic herbs from steel foundry effluent

Discharge of industrial effluents in aquatic environments is a serious threat to life due to toxic heavy metals. Plants can be used as cheap phytoremedients in comparison to conventional

The Role of Heavy Metals-Resistant Bacteria Acinetobacter sp. in Copper Phytoremediation using Eichhornia crasippes [(Mart.) Solms]

The results showed that inoculation treatment enhanced the potency of the plant to reduce copper from  94 % concentration level in the medium without bacterial inoculation to 98.3 % and 97 % in medium inoculated with Acinetobacter sp.

Enhanced disappearance of mesotrione and fomesafen by water hyacinth (Eichhornia crassipes) in water

Results show that uptake by plants combined with degradation by plant-associated bacteria may be the dominant process in the removal of mesotrione and fomesafen from water by plants.


The capacity to solubilize inorganic phosphates by phosphate-solubilizing bacterial strains isolated from soil samples collected from different agricultural fields in Matara District was assessed.

Plants as extreme environments? Ni-resistant bacteria and Ni-hyperaccumulators of serpentine flora

This paper aims to provide a state of the art and to present possible future directions for research which could lead to new insights on microbial adaptation and evolution, and potentially applied in technologies for sustainable use and remediation of contaminated land.



Behaviour of Bacterial Populations Isolated from Rhizosphere of Diplachne fusca Dominant in Industrial Sites

The increase in metal ion uptake (especially Cr, Pb, Zn and Ni) by D. fusca was correlated with higher numbers of siderophore-producing, phosphate-solubilizing and acid-producing bacteria 95, 81 and 64%, respectively.

Aerobic chromate reduction by chromium-resistant bacteria isolated from serpentine soil.

Toxicity of Hexavalent Chromium and Its Reduction by Bacteria Isolated from Soil Contaminated with Tannery Waste

Assays with permeabilized cells and crude extracts demonstrated that the Cr(VI) reduction was mainly associated with the soluble protein fraction of the cell, suggesting that Arthrobacter sp.

Phytoaccumulation of heavy metals by aquatic plants.

Characterization of nickel-resistant bacteria isolated from serpentine soil.

Heterotrophic nickel-resistant bacteria were isolated and characterized from three different serpentine outcrops in central Italy populated by the nickel-hyperaccumulating plant Alyssum bertolonii and Pseudomonas strains were found to be predominant in the plant rhizosphere, whereas Streptomyces strains were mainly present in the soil.

Hexavalent-chromium reduction by a chromate-resistantBacillus sp. strain

Studies with permeabilized cells and cell extracts showed that the Cr(VI) reductase of strain QC1-2 is a soluble NADH-dependent enzyme.
