The aim of this study was to assess the effects of inoculation of rhizosphere or endophytic bacteria (Psychrobacter sp. SRS8 and Pseudomonas sp. A3R3, respectively) isolated from a serpentine environment on the plant growth and the translocation and accumulation of Ni, Zn, and Fe by Brassica juncea and Ricinus communis on a multi-metal polluted serpentine soil (SS). Field collected SS was dilut...

This work deals with bioremediation of dredged sediments contaminated by heavy metals. Consortia of acidophilic bacteria were added to sediments collected from the Ancona harbor (Adriatic Sea) in order to test their ability to remove heavy metals and thus to obtain valuable material suitable for different purposes (e.g. building industries or beaches nourishment). The efficiency of different ba...

Application of hyperaccumulator-endophyte symbiotic systems is a potential approach to improve phytoremediation efficiency, since some beneficial endophytic bacteria are able to detoxify heavy metals, alter metal solubility in soil, and facilitate plant growth. The objective of this study was to isolate multi-metal resistant and plant beneficial endophytic bacteria and to evaluate their role in...

Metal cation homeostasis is essential for plant nutrition and resistance to toxic heavy metals. Many plant metal transporters remain to be identified at the molecular level. In the present study, we have isolated AtNramp cDNAs from Arabidopsis and show that these genes complement the phenotype of a metal uptake deficient yeast strain, smf1. AtNramps show homology to the Nramp gene family in bac...

Industrially polluted streams and rivers are of great concern to public health officials and environmental regulators. A lesser known problem is that some water resources have become reservoirs of antibiotic resistance genes that can, under natural conditions, be transferred to water-borne pathogens. The current opinion in the scientific community is that the rapid and continuing increase in an...

In this study, a relationship between antibiotic and heavy metal resistance was estimated among culturable bacterial strains of agriculture farm soap industry soil.A total 27 were isolated screened for their by supplementing LB agar medium with variable concentrations respectivestress. On LB-agar medium, soil harboured more cultivable (17 strains) as compared to the (10 strains).Minimum inhibit...
