The present study evaluated the efficacy of dietary doses of Withania somnifera (Ashwagandha) root powder on immunological parameters and disease resistance against the bacterial pathogen Aeromonas hydrophila infections in Indian major carp, Labeo rohita fingerlings. Fishes were fed with dry diet containing 0gkg-1 (control), 1gkg-1 (T1), 2gkg-1 (T2) and 3gkg-1 (T3) W. somnifera root powder for 42 days. Immunological (NBT level, Phagocytic activity, total immunoglobulin and lysozyme activity) parameters of fishes were examined at 0 days,14 days, 28 days and 42 days of feeding. Fishes were challenged with A. hydrophila 42 days post feeding and mortalities (%) were recorded over 14 days post-infection. The results demonstrate that fishes fed with W. somnifera root showed enhanced NBT level, Phagocytic activity, total Immunoglobulin level and lysozyme activity (p<0.05) compared with the control group. The survivability was higher in experimental diets than the control group. Dietary W. somnifera at the level of 2gkg-1 showed significantly (P<0.05) higher protection (RPS 42.85±0.65%) against A. hydrophila infection than control. The results suggest that the W. somnifera root powder have a stimulatory effect on immunological parameters and increases disease resistance in L. rohita fingerlings against A. hydrophila infection. © 2010 Elsevier Ltd.

We are reporting highly economical plant-based hydrothermal method for one-pot green synthesis of water-dispersible fluorescent carbon dots (CDs) by using Saccharum officinarum juice as precursor. The synthesized CDs were characterized by UV-visible, fluorescence, Fourier transform infrared (FT-IR), dynamic light scattering (DLS), high-resolution transmission electron microscopic (HR-TEM), and laser scanning confocal microscopic techniques. The CDs are well dispersed in water with an average size of ~ 3 nm and showed bright blue fluorescence under UV-light (λex = 365 nm). These CDs acted as excellent fluorescent probes in cellular imaging of bacteria (Escherichia coli) and yeast (Saccharomyces cerevisiae). © 2014 Elsevier B.V. Source

Twenty five different arsenite (AsIII) oxidising bacteria were isolated from industrial effluent (Bilimora, Gujarat Industrial Development Corporation (GIDC) Gujarat, India). The most efficient arsenite oxidiser and arsenite hyper-tolerant bacterial isolate which could tolerate up to 15 mM AsIII was selected and 16S rRNA gene sequence analysis was performed. It showed 98% identity of the 16S rRNA genes of genus Alishewanella (Accession no.: HQ659190). Higher activities of arsenite oxidase enzymes in the bacterium were localised on membrane. The GIDC-5 bacterial strain was found to be susceptible to most of the common antibiotics. The optimum growth in the presence of metalloid was observed at temperature 37°C and pH 4, whereas in the absence of metalloid the optimum pH was 8. The result suggested that, Alishewanella sp. strain GIDC-5 demonstrated hyper-tolerant to arsenite because of its ability to overcome the toxic effects of arsenite by converting it to less toxic forms (arsenate). © 2013 Copyright Taylor and Francis Group, LLC.

We have synthesized biocompatible fluorescent carbon dots (CDs) by a one-step hydrothermal method using Solanum tuberosum (potato) as a raw material. The CDs were characterized by UV-visible, fluorescence, Fourier transform infrared (FT-IR), X-ray diffraction (XRD), thermogravimetric analysis (TGA), dynamic light scattering (DLS) and high-resolution transmission electron microscopic (HR-TEM) techniques. We found that the carbonization of potato at ∼170 °C for 12 h produces highly fluorescent CDs of 0.2-2.2 nm size. The synthesized CDs are well dispersed in water and exhibited strong blue and bright blue emissions under UV illumination (λex = 302, 365 nm). The CDs showed a strong emission peak at 455 nm at an excitation wavelength of 374 nm. The CDs acted as fluorescent probes for multicolor (blue, green and red) imaging of HeLa cells and the CDs did not induce cell death, which indicates that the CDs are biocompatible and nontoxic to HeLa cells. Therefore, the CDs can be used as probes for cell-imaging applications in vitro and in vivo.
