© 2017 John Wiley & Sons Ltd Many aquatic plants act as biosorbents, removing and recovering metals from the environment. To assess the biosorbent activity of Egeria densa, a submerged freshwater macrophyte, plants were collected monthly from a circular drainage area in Lake Biwa basin and the Mn concentrations of the plants were analysed. Mn concentrations in these plants were generally above those of terrestrial hyperaccumulators, and were markedly higher in spring and summer than in autumn. Mn concentrations were much lower in plants incubated in hydroponic medium at various pH levels with and without Mn supplementation than in field-collected plants. The precipitation of Mn oxides on the leaves was determined by variable pressure scanning electron microscopy-energy dispersive X-ray analysis and Leucoberbelin blue staining. Several strains of epiphytic bacteria were isolated from the field-collected E. densa plants, with many of these strains, including those of the genera Acidovorax, Comamonas, Pseudomonas and Rhizobium, found to have Mn-oxidizing activity. High Mn concentrations in E. densa were mediated by the production of biogenic Mn oxide in biofilms on leaf surfaces. These findings provide new insights into plant epidermal bacterial flora that affect metal accumulation in plants and suggest that these aquatic plants may have use in Mn phytomining.

Metallomics: Recent Analytical Techniques and Applications 125 - 145 2017.1

Language：English Publishing type：Research paper (scientific journal) Publisher：Metallomics: Recent Analytical Techniques and Applications

© Springer Japan KK 2017. X-ray microanalyses have been utilized to determine mechanisms of metal detoxification and homeostasis in plants and are powerful tools, especially for target plants unsuitable for genetic analyses. This chapter describes several synchrotron-based research methods to determine metal element distribution and speciation of metal-accumulating plants. The procedures are described, to show how micro-X-ray techniques are applicable to various biological materials, including those that are solid or liquid, soft or hard, or wet or dry. Combination of X-ray microanalysis with other methodologies, including TEM (transmission electron microscope), SEM (scanning electron microscope), and techniques of biochemistry and molecular biology, is described. Overall, this chapter attempts to encourage cross-disciplinary work in metallomics.
