Characterization of Roseomonas and Nocardioides spp. for arsenic transformation

Prospective role of indigenousExiguobacterium profundumPT2 in arsenic biotransformation and biosorption by planktonic cultures and biofilms

“…Some other species of this genus have already been reported to resist As Pandey and Bhatt 2016). The tolerance of As 5+ against E. profundum PT2 in LB and AWWE reported in this study is one of the highest As tolerance levels by any bacterial isolate reported previously (Kaur et al 2009;Rehman et al 2013;Bagade et al 2016;Maizel et al 2016;Pandey and Bhatt 2016;Jebeli et al 2017).…”

“…The results of Pandey and Bhatt () and Bagade et al . () exhibited 443 μ mol l −1 and 2 mmol l −1 transformation of As after 48‐ and 36‐h incubation by Exiguobacterium and Nocardioides sp., respectively. In this study, maximum As biosorption capacity of the bacterial biomass was found to be 25·2 mg As g −1 after 48‐h incubation as shown in Fig.…”

“…Many studies have been conducted to explore different ways of transforming or removing As. Such studies have also been widely carried out by using bacteria as many exhibit As resistance, transformation and detoxification (Kao et al 2013;Ghosh et al 2015;Bagade et al 2016;Zhang et al 2016). Few studies have reported arsenic transformation along with biofilm parameters.…”

“…Microbial As 5+ reduction may be carried out by using As 5+ as an electron acceptor or as a part of As detoxification mechanism by As 5+ reductase (Zhang et al 2015). However, heterotrophic bacteria overcome As stress through As 3+ oxidation, while chemoautotrophic bacteria use energy derived from As 3+ oxidation (Zhang et al 2015;Bagade et al 2016;Sanyal et al 2016). Some bacteria perform redox transformation of As and the two processes (As oxidation and reduction) cannot be separated from one another.…”

Potential of Halophilic Bacteria for Extracellular Enzymes

“…The enzymes like amylase, lipase, caseinase and cellulase were studied by Joshi et al, (2008). Arsenic oxidizing and arsenic reducing bacteria have been recently reported from Lonar Lake (Bagade et al, 2016). Alkaline enzymes like protease have been optimized by Rathod and Pathak (2016).…”
