Bacillus cereus, selenite-reducing bacterium from contaminated lake of an industrial area: a renewable nanofactory for the synthesis of selenium nanoparticles

“…E5 (Durán et al 2015), B. licheniformis (Khiralla and El-Deeb 2015), B. subtilis (Wang et al 2010), etc. Other reported aerobic strains are Pseudomonas agglomerans, (Torres et al 2012), P. aeruginosa JS-11 (Dwivedi et al 2013), P. stutzeri (Lortie et al 1992), P. alcaliphila (Zhang et al 2011), Duganella sp., Agrobacterium sp. (Bajaj et al 2012), Zooglea ramigera (Srivastava and Mukhopadhyay 2013), Streptomyces minutiscleroticus M10A62 (Ramya et al 2015), Acinetobacter sp.…”

“…HN-41 (Tam et al 2010), Bacillus sp. , Escherichia coli K-12 (Dobias et al 2011), P. alcaliphila (Zhang et al 2011), and Pantoea agglomerans (Torres et al 2012). It is well known that the selenium nanoparticles generated by biological reduction are, indeed, characteristically amorphous in nature (Torres et al 2012).…”

“…Selenite-reducing bacteria have been isolated from a variety of environments including Mono Lake of California (Oremland et al 2004), Dead sea, a salt lake (Oremland et al 2004), Caspian sea of Iran (Shakibaie et al 2015), sediments of Cama-rones river from Atacama desert, Northern Chile (Torres et al 2012), activated sludge (Srivastava and Mukhopadhyay 2013), sludge of Taiyuan sewage plant, China (Li et al 2014), drainage slough from Nevada (Oremland et al 2004), and anaerobic granules from paper mill wastewater treating reactor (Jain et al 2015). In addition, from the soil of a antimony mine from Lengshuijiang, southern China (Zheng et al 2014), soil of a magnesite mine from Salem, India (Ramya et al 2015), soil of a coal mine from West Bengal, India (Dhanjal and Cameotra 2010), selenium laden agricultural soil of North-East Punjab, India (Bajaj et al 2012), soil of mangrove forest from Bhitarkanika, Orissa, India (Mishra et al 2011), rhizosphere soil of a selenium hyperaccumulator legume grown in seleniferous mine from Sardina, Italy (Lampis et al 2014), rhizosphere of wheat grown in herbicide contaminated soil (Dwivedi et al 2013), and rhizosphere of cereal plants grown in ash-derived volcanic soil of southern Chile (Durán et al 2015).…”

“…A wide variety of properties shown by selenium nanoparticles are free radical scavenging (Huang et al 2003), antioxidant (Forootanfar et al 2014;Kong et al 2014;Mittal et al 2014;Ramya et al 2015;Rezvanfar et al 2013;Torres et al 2012;, chemoprotection against chemotherapy-induced reproductive toxicity (Rezvanfar et al 2013) and UV-induced DNA damage (Prasad et al 2013), immunomodulatory, anti-inflammatory (Wang et al 2014), nanomedicinal , chemotherapeutic and chemoprevention against human melanoma and hepatoma cancers Estevez et al 2014;Peng et al 2007), biofortification (Durán et al 2015), and antitumor and anticancer (Jia et al 2015;Kumar et al 2015;Mittal et al 2014;Ren et al 2013) activities. Other applications include antibacterial, antibiofilm (Bartůněk et al 2015;Hariharan et al 2012;Huang et al 2016;Mittal et al 2014;Ramya et al 2015;Shakibaie et al 2015;Tran and Webster 2011;Wang and Webster 2013), antifungal, antiprotozoan, antitapeworm (Bartůněk et al 2015), antiviral, wound healing (Ramya et al 2015), and cytotoxic (Forootanfar et al 2014;Ramya et al 2015) activities.…”

Chitosan-decorated selenium nanoparticles as protein carriers to improve the in vivo half-life of the peptide therapeutic BAY 55-9837 for type 2 diabetes mellitus

“…23,24 Se possesses many beneficial properties, including antioxidant, antiapoptotic, anticancer, and immune-system enhancements. [25][26][27] However, its beneficial properties occur within a limited range. In comparison with Se, SeNPs possess lower toxicity as chemotherapeutic agents.…”
