<P>Current study aimed at exploring the diversity of bacterial endophytes with Boswellia sacra and their role in copper (Cu) stress to tomato plants. Bacterial endophytes were belonged to Bacillus, Rhizobium and Paenibacillus, which were screened against Cu (0=10 mM) stress to dwarf and normal rice seeds. Among strains, Bacillus amyloliquefaciens BSL16 showed significantly higher bioremediation potential by accumulating high Cu and promoting growth of rice seeds. B. amyloliquefaciens BSL16 significantly increased growth of tomato plants during 2.5 mM Cu stress. Active colonization of BSL16 reduced the accumulation of Cu in leaf, shoot, and root, and in parallel up-regulated total protein contents in leaf and stem. Glutathione peroxidase and reduced glutathione contents were significantly higher and lipid peroxidation was lower in endophyte-treated tomato plants as compared to Cu treatment. The current results conclude that application of metal bio-accumulating bacteria can help in improving the plant growth of tomato plants during Cu stress.</P>

Clean drinking water has been a vital topic of research in modern world, this makes efficient water purification asthe latest demand. The research and development in the field of filtration technology has revitalize considerable awareness indifferent engineered methods and nanomaterials. In this work, a hydrophobic composite fibers was successfully prepared byincorporating ZnO nanofiller into polyvinylidene fluoride (PVDF) using an electrospinning method for organic dyedegradation and oil absorption applications. The hydrothermal method was used to prepare pure ZnO. The structuralproperties of PVDF/ZnO composite fibers and pure ZnO were studied using the X-ray diffraction technique (XRD). TheSEM image of pure ZnO shows a flower-like structure and the composites exhibited the structure of the fibers. The averagefiber diameter of the pure PVDF fiber was around 625 nm and the PVDF/ZnO composite fiber was around 485 nm,respectively. Finally, the prepared fibers were tested for oil absorption and the photocatalytic degradation of organic dyes. The photocatalytic activity of PVDF/ZnO was evaluated by the degradation of Azocarmine G (AZG) and Malachite green(MG) dye under sunlight irradiation. The results showed that 85 % of AZG and 90 % of MG dye could be degraded within120 min and 240 min. It was found that the PVDF/ZnO composite fiber was hydrophobic (135 °) under water. Good oilabsorption efficiency (115 %) was achieved using PVDF/ZnO composite fibers. The results shows that the preparedcomposite fibers can be used to absorb oil and degrade organic contaminants. This cost-effective, easy operation, reusability,and efficiency of the PVDF/ZnO fiber mats could be potentially useful for water treatment and oil recovery.

One of the most exciting areas for the development of alternative fuels is the production of biodiesel. To reduce the cost of biodiesel production, in situ trans-esterification has been introduced to simplify the production process by enabling extraction and trans-esterification to occur at a single stage in the presence of a catalyst. In this study, we investigated the feasibility of using non-corrosive and environmentally receptive flying jet plasma as an alternative catalytic route for in situ tran-sesterification of castor bean seeds (CBS). Upon optimizing the reaction conditions, it is elucidated that applying a low ratio of methanol to seeds (≤6:1) has resulted in hindering the in situ trans-esterification and leading to insignificant conversion. The yield of esters has increased from 80.5% to 91.7% as the molar ratio rose from 9:1 to 12:1. Excess alcohol beyond the ratio of 15:1 was shown to have a negative impact on the yield of the produced esters, attributed to an increase in the biodiesel portion prone to dissolving in the co-product (glycerol). An increase in the reaction bulk temperature from 40 to 55 ℃ led to a higher ester content by 50%. Further increases in the bulk temperature beyond 55 ℃ did not affect yields. Regarding the reaction period, the results have shown that 3 h of reaction is adequate for a higher biodiesel yield. The quality of the biodiesel obtained has demonstrated that all physicochemical properties meet the ASTM D6751 specifications.
