  It has been well recognized that microbes can assist phytoremediation of lead (Pb) by promoting plant growth and metal uptake. However, little is known about the potential of soil inoculation with actinomycetes to enhance Pb uptake and translocation in plants, particularly in semi-arid water-deficient areas. This study was focused on exploring the resistance of a soil actinomycete strain (Streptomyces pactum Act12) to Pb and its effects on plant growth, antioxidant responses, Pb uptake and translocation in perennial ryegrass (Lolium perenne L.). Special attention was given to experimental conditions in semi-arid area in Northerwest China. A fermentation culture of Act12 was applied in powder form to soil with or without Pb treatment (0–1,000 mg kg-1), and ryegrass plants were immediately grown in this soil, in pots, for 60 days under 20% relative soil moisture. Act12 showed tole.. View More»
