Lead oxalates in some Chinese leafy vegetable cultivation: their biomineralization and remediation by oxalate degrading Streptomyces sp.

ABSTRACT: Heavy metal contamination is a global threat with far-reaching effects for both human health and the environment. Biological agents, such as plants and microorganisms, provide uncomplicated and eco-friendly ways of removing toxic metals; thus, they are regarded as successful and alternative tools. In this study, we evaluated the ability of Streptomyces NJ10 (SN10), an oxalotrophic bacterium with outstanding oxalate metabolizing potential, to convert toxic lead oxalate (PbOx) into lead carbonate (PbCO₃). SN10 was therefore used to determine the reduction of toxicity of Chinese leafy vegetables grown in the presence of PbOx in the soil. When compared to control, SN10 treated pots showed improved plant growth characters, i.e. shoot length (5.85 ± 0.56 cm), average leaf area
