| Abstract | Acid mine drainage (AMD) poses serious environmental problems. This study assessed the effect of plant age, rhizosphere bacteria, and citric acid (CA) on the metal plaque formation and metal uptake in Phragmites australis cultured in a synthetic AMD solution. Iron-oxidizing bacteria (Fe(II)OB) enhanced the formation of Fe plaque, which slightly decreased Fe and Mn uptake. CA reduced the growth of Fe(II)OB and formation of Fe plaque, thereby increasing the Fe and Mn accumulations in reeds. Adult reeds had developed more Fe plaque on the root surface than seedlings. However, the adult reeds still accumulated higher concentrations of metals due to their higher tolerance to toxic environments and bigger biomass. With 9.02 g/L CA, adult reeds accumulated 0.51 ± 0.00 mg Mn, 109.38 ± 1.37 mg Fe, and 1.77 ± 0.04 mg Al. More investigation may be needed to further study the effect of CA when applied to AMD-contaminated field. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
