This work comprised of the comparative study of arsenic (As) uptake efficiency by Pteris vittata and Pityrogramma calomelanos grown in (i) As amended soils (0–600 ppm) and (ii) As tainted water (40 ppb) using a new compact continuous flow phytofiltration system in a tropical greenhouse. The As hyperaccumulation efficiency was dependent on the growth medium for the two fern species. The highest level of As detected in the fronds of P. vittata was 19,300 ± 190 ppm (dry weight basis) and 11,600 ± 230 ppm for Pityrogramma calomelanos, after growing for 78 days in soils amended with As. In the compact continuous flow As phytofiltration system experiments, Pityrogramma calomelanos was found to perform better than P. vittata in phytofiltrating As contaminated water under waterlogged conditions. During the 167 h of phytofiltration experiment, the removal efficiency was approximately 99% and 67% for Pityrogramma calomelanos and P. vittata systems respectively, based on an initial 40 ppb As. Pityrogramma calomelanos also required a shorter acclimatization time than P. vittata under waterlogged conditions.

Pre Treatment

As a strategy of arsenic-containing mine tailing soil, the application of arsenic hyper-accumulator plants such as Pteris vittata shows high potential. Previous studies suggest that the arsenic uptake by P. vittata is largely determined by arsenic speciation, which is strongly influenced by microbial activities. In this study, two arsenic hyper-accumulators, P. vittata that is a subtropical plant and Pteris multifida that has been found in northeastern Japan, were selected and the their rhizobacteria were investigated. Pot experiments of P. vittata and P. multifida cultivation were performed. The concentration of total arsenic in the plant samples was monitored by inductively coupled plasma - mass spectrometry. Microbes in the rhizosphere samples were investigated by 16S rDNA library analysis and arsenic resistant bacteria isolation. The results showed that both ferns accumulated As, while P. multifida was more resistant to cold weather. Two ferns presented different rhizobacterial communities and cultivatable bacteria number, but bacteria that contain As(III) oxidase gene or As(III) oxidation activity were confirmed in both rhizosphere samples. The results of present study suggested that the cultivation of ferns changed the microbial communities in soil (rhizosphere), and microbial activity in the rhizosphere played a role in As(III) oxidation. Since ferns absorbs As(III) and As(V) in different efficiency, this study provided hints when linking microbial As transformation to As uptake by ferns which is important when designing pre-treatment procedures of phytoremediation.
