Rhodococcus pyridinivorans strain UCC 0003
Opis:
Methylene blue is a toxic dye present in the textile industry, and if left untreated, it causes harm to the environment. Therefore, to decolorize methylene blue from industrial effluents, a green approach using Rhodococcus pyridinivorans strain UCC 0003 was attempted. Methylene blue decolorization was measured spectrophotometrically, and the static condition yielded 86% decolorization after 24 h as compared to the shaking mode (20%). Optimization of static conditions using the one-factor-at-a-time approach resulted in 100% decolorization at 30EC, pH 6, inoculum size of 16% (v/v), and 5% (v/v) banana peel addition as a carbon source. The R. pyridinivorans strain UCC 0003 could successfully and completely decolorize 0.75 g/l methylene blue for 4 consecutive cycles, which is advantageous from an economic point of view. The rate of methylene blue disappearance was investigated using 10% (v/v) R. pyridinivorans strain UCC 0003 at 30EC over a certain incubation time with 0.4 g/l to 10.0 g/l methylene blue as the substrate. This study revealed Vmax and Km values of 37.04 g/l/h and 55.69 g/l, respectively, as the kinetic behavior of methylene blue-decolorizing enzymes from the bacterial strain. The properties of the treated solution of methylene blue resembled the control system (distilled water) for the phytotoxicity study, thereby indicating the complete removal of dye toxicity as evidenced by the growth of Vigna radiata and Triticum aestivum, respectively, in the treated methylene blue solution. This local bacterial strain has therefore a huge potential to be used as a green biocatalyst for the bioremediation of methylene blue-containing industrial effluents.

Opis:
$Ag_2Cu_2O_3$ films were deposited on glass and silicon substrates by RF magnetron sputtering of metallic equimolar $(Ag_{50}Cu_{50})$ alloy target in $Ar-O_{2}$ mixture at different substrate temperature $(T_{s})$ ranging between 303 and 523 K. The effect of $T_{s}$ on the core level binding energies, structural and electrical properties of the films was systematically studied. The films deposited at room temperature were amorphous. The films deposited at 373 K were polycrystalline and the crystallinity was increased when the $T_{s}$ was increased to 423 K. The films deposited at 423 K and subsequently annealed at 498 K exhibits single phase $Ag_2Cu_2O_3$. In the case of films deposited at higher $T_{s}$ of 523 K, $Ag_2O$ was decomposed into Ag. The electrical resistivity of the films deposited at 303 K was $1.2 \times 10^{-5}$ Ω cm, whereas the films formed at 423 K and subsequently annealed at 498 K showed electrical resistivity of $2.2 \times 10^{-3}$ Ω cm due to improvement in the crystallinity of single phase $Ag_2Cu_2O_3$.

Opis:
This paper presents the study of the tensile properties of Sansevieria trifasciata – fiber (here after called STF) reinforced polyester composites. The composite sample was fabricated with five different fiber lengths of STF (2, 4, 6, 8 and 10 mm). The fabrication was made by hand lay-up technique. Mechanical properties were determined using tensile testing. An interact between fiber and matrix was observed from the SEM (scanning electron microscope) micrographs. The study reveals that the tensile strength increased with fiber length without effecting the elongation at break of the composite.
