Out of the 40 fungal cultures screened, one fungus Gliocladium sp. was found to produce taxol and 10-DABIII (10-deacetyl baccatin III). These compounds were purified by TLC and HPLC and characterized using UV-spectroscopy, ESI-MS, MS/MS, and proton NMR. One liter of Gliocladium sp. culture yielded 10 mu g of taxol and 65 mu g of 10-DABIII. The purified taxol from the fungus showed cytotoxicity towards cancer lines HL-60 (leukemia), A431 (epidermal carcinoma), and MCF-7 (breast cancer).</p>10a10 DAB III10aEndophytic fungi10aGliocladium sp.10aTaxol10aTaxus baccata1 aSreekanth, D.1 aSyed, A.1 aSarkar, S.1 aSarkar, Dhiman1 aSanthakumari, B.1 aAhmad, Absar1 aKhan, Mohammad, Islam  uhttps://library.ncl.res.in/content/production-purification-and-characterization-taxol-and-10-dabiii-new-endophytic-fungus-002339nas a2200349   4500008004100000022001400041245011900055210006900174260000800243300001400251490000700265520127700272653001301549653001701562653003501579653002401614653000801638100001501646700002001661700001501681700001901696700001801715700001501733700001901748700001401767700002001781700001301801700001701814700001501831700001201846856013101858       2019                        eng d  a0272-884200aRole of Li+ and Fe3+ in modified ZnO: Structural, vibrational, opto-electronic, mechanical and magnetic properties0 aRole of Li and Fe3 in modified ZnO Structural vibrational optoel  cJAN  a7232-72430 v453 aWhen Fe is doped in ZnO, a situation of charge imbalance is created due to the higher charge of Fe3+. A charge balance may be obtained by co-doping Li+0.5Fe3+0.5 combinations. A solid solution of Zn1-x(Fe0.5Li0.5)xO (0 ≤ x ≤ 0.03125) is synthesized with this viewpoint. The crystallites belong to a wurtzite P63mc space group, with lattice parameters a, b and c increasing nominally for x = 0.0156 and thereafter remaining invariant. The size varies in the range ~ 60–142 nm. Interstitials of Li and Zn ions are formed. Along with Fe3+ substitution these defects are reasons for O interstitials. These oxygen interstitials increase the red emission while reduction of oxygen vacancies reduces the green emission. These point defects create structural distortion and strain which can generate Zn vacancies. Bandgap reduces due to shallow defects. Mid-bandgap states due to oxygen interstitials and Fe 3d-O 2p hybridization result in NIR emission. On the other hand the crystal surface deforms due to Li addition which hardens the materials. A weak ferromagnetism appears at very low temperature which is enhanced by Li+ addition. Long range exchange mechanism between Fe3+ ions appears in the samples, mediated by magnetic polarons due to point defects.10ahardness10aNIR emission10aShallow and deep level defects10aWeak ferromagnetism10aZnO1 aBajpai, G.1 aMoirangthem, I.1 aSarkar, S.1 aBarman, S., R.1 aVinod, C., P.1 aBajpai, S.1 aRiyajuddin, S.1 aGhosh, K.1 aBasaula, D., R.1 aKhan, M.1 aLiu, S., -W.1 aBiring, S.1 aSen, S.  uhttps://library.ncl.res.in/content/role-li-and-fe3-modified-zno-structural-vibrational-opto-electronic-mechanical-and-magnetic
