“…These results are compared with earlier study carried out on biosynthesis of selenium nanoparticles with marine bacterial strain Bacillus sp. MSh-1, in which nanoparticles in size range of about 80-220 nm were obtained (Forootanfar et al 2014), while the probiotic lactic acid bacteria such as Lactobacillus and Bifidobacter produced selenium nanoparticles in the size ranges of 100-200 and 400-500 nm, respectively (Eszenyi et al 2011). From the data, it is evident that the strain B. cereus is able to produce selenium nanoparticles with smaller average nanoparticle size and narrow particle size distribution.…”

Background: An attempt was made to isolate selenite-reducing bacteria from a contaminated lake that receives industrial effluents and domestic sewage. The isolated dominant bacterial strain AJK3 was identified as Bacillus cereus, based on biochemical characterization and 16S rDNA sequencing. The time dependent selenium removal at different selenite concentrations monitored with ICP-AES indicates the substantial selenite reduction capability of the isolated strain. The selenium nanoparticles produced during the bacterial reduction of selenite were analyzed with UV-visible spectroscopy, X-ray diffraction, transmission electron microscopy, zeta potential measurement, Fourier transform infrared spectroscopy and Raman spectroscopy. Results:The nanoparticle synthesis was confirmed from the red colour emergence in culture broth and wide UV-vis peaks. The produced nanoparticles were polydisperse, spherical, size varied from 50 to 150 nm and the mean particle size was about 93 nm. The amorphous nature of the generated nanoparticles was confirmed from the Raman spectroscopy, XRD and SAED patterns. The IR data and zeta potential values substantiated the protein capping of the produced nanoparticles. Conclusions:Thus, the present study suggests that the isolated bacterial strain can be exploited as a prospective, renewable, natural, nanofactory for the bacteriogenic synthesis of nanoparticles. Also, the study has application in bioremediation of selenite from the contaminated environment.

The aim of this study was to synthesize selenium nanoparticles (SeNPs) using cell suspension and total cell protein of Acinetobacter sp. SW30 and optimize its synthesis by studying the influence of physiological and physicochemical parameters. Also, we aimed to compare its anticancer activity with that of chemically synthesized SeNPs in breast cancer cells. Cell suspension of Acinetobacter sp. SW30 was exposed to various physiological and physicochemical conditions in the presence of sodium selenite to study their effects on the synthesis and morphology of SeNPs. Breast cancer cells (4T1, MCF-7) and noncancer cells (NIH/3T3, HEK293) were exposed to different concentrations of SeNPs. The 18 h grown culture with 2.7×10 9 cfu/mL could synthesize amorphous nanospheres of size 78 nm at 1.5 mM and crystalline nanorods at above 2.0 mM Na 2 SeO 3 concentration. Polygonal-shaped SeNPs of average size 79 nm were obtained in the supernatant of 4 mg/mL of total cell protein of Acinetobacter sp. SW30. Chemical SeNPs showed more anticancer activity than SeNPs synthesized by Acinetobacter sp. SW30 (BSeNPs), but they were found to be toxic to noncancer cells also. However, BSeNPs were selective against breast cancer cells than chemical ones. Results suggest that BSeNPs are a good choice of selection as anticancer agents.

The aim of this study was to investigate the efficacy of selenium nanoparticles (SeNPs) that had been biologically synthesized by Bacillus licheniformis to counteract deoxynivalenol (DON) toxicity in laying hens. Ninety-six healthy, 20-week-old laying hens were randomly assigned to four treatment groups, each of which included 3 replicates of 8 layers, and fed four different diets: an uncontaminated basal diet (control group), a 10 mg/kg DON-contaminated basal diet (DON group), a 10 mg/kg DON-contaminated basal diet with 0.5 mg/kg SeNPs (DON+SeNPs group) and the basal diet with 0.5 mg/kg SeNPs (SeNPs group).Serum T-AOC and GPx activities were significantly decreased (P<0.05) in hens fed the DON-contaminated diet, and DON significantly decreased the egg production rate (P<0.05), significantly increased the soft-shelled or cracked egg rate (P<0.05), significantly decreased serum calcium and inhibited the immune systems of the animals according to blood routine indexes. However, SeNPs improved the levels of GPx and T-AOC, increased the egg production rate, significantly decreased the soft-shelled or cracked egg rate (P<0.05), and decreased the influence of DON on the blood routine.In addition, SeNPs significantly (P<0.05) increased serum calcium. However, no differences were observed in egg quality (egg weight, Haugh units, yolk color, eggshell strength and eggshell thickness) among the four groups. These results showed that SeNPs could provide effective anti-oxidative protection against DON toxicity in laying hens, reduced DON's influence on egg production and blood calcium
