the study applied an isolated brevibacterium sp. (mtcc 10313) for bioremediation of zn, cu, mg and pb in domestic sewage. batch culture experiments were performed on both the fresh and stale sewage samples with glucose supplementation of 1-8g/l. nutrient broth medium was prepared, sterilized and ph adjusted to 6.5-6.8. 1% of the brevibacteria sp. stock was inoculated into the broth and maintain...
the present study was aimed at comparing the ability of three crop plants for phytoremediation of zinc (zn) and nickel (zn) from soils. a factorial (3×2×3) experiment based on rcbd was used to compare the treatments, and was repeated three times. the first factor was crop type (wheat, clover and rapeseed), the second factor was heavy metal types (zinc (zn) and nickel (ni)) and the third fac...

the present study is aimed at assessing the ability of pseudomonas sp. an29 to uptake hg2+ from the metal contaminated environment. the minimum inhibitory concentration (mics) of hg 2+ was 500 μg/ml. pseudomonas sp. an29 could tolerate pb 2+ (600 g/ml), cu2+ (200 g/ml), cd2+ (50 g/ml), zn2+ (50 g/ml), ni2+ (550 g/ml) and cr 6+ (150 g/ml). the isolate showed typical g...
This research aims to study the effect of Mycorrizal fungus and Plant-Growth-Promoting Bacteria (PGPB) on Cadmium (Cd) uptake by one-year-old Eucalyptus Camaldulensis seedlings. The treatments have involved three levels of heavy metal (0, 30, and 60 mg/kg) for Cd, and three bacterial levels (no bacteria (B0), Bacillus (Ba105), and Pseudomonas (Ps36, Ps448)), inoculated with mycorrhizal fungus G...

Land application of sewage sludge is potentially beneficial as an inexpensive nutrient source. However, problem with the use of sludge may exist from high soil concentrations and subsequent uptake of heavy metals by plant and entering of the metals into the human and animal food chains. A field study with lettuce (Lactuca sativa L.) and spinach (Spinacia oleracea L.) was conducted to examine up...

background: phytoremediation is one of the methods used to remove contaminants and while being simple, cheap and efficient, does not cause environmental deterioration. the aims of this study were phytoremediation of soil contaminated by cd, the simultaneous survey of the influence of different electrical conductivity values, and comparison of two soil amendments including sludge and municipal c...
28 Metal uptake is vital for all living organisms. In metal scarce conditions, a common bacterial 29 strategy consists in the biosynthesis of metallophores, their export in the extracellular medium 30 and the recovery of a metal-metallophore complex through dedicated membrane transporters. 31 Staphylopine is a recently described metallophore distantly related to plant nicotianamine that 32 cont...
