1 Results The potential applications of small-, medium-and large-size polyaromatic hydrocarbons for charge and energy storage in lithium metal and lithium ion batteries are discussed. In order to find the best carbon-based electrode materials, the specific roles of the molecular and solid-state contributions have to be understood. For the molecular contributions, a semi-quantitative method is proposed to compare the charge storage capability of polyaromatic hydrocarbon molecules. A compilation of result...

polyaromatic Hydrocarbon Degradation of Moss Endophytic Fungi Isolated from Macromitrium sp. in Sri Lanka

引用

Journal of Agricultural Science and Technology(A) 2016年第3期6卷 171-182页

作者： Sagarika Kannangara Punnaja Ambadeniya Lanka Undugoda Krishanthi Abeywickrama Department of Botany University of Kelaniya Kelaniya 11600 Sri Lanka

polyaromatic hydrocarbons （PAHs）, which are the major by-products of fossil fuel burning, are released to the environment with the immense growth of urbanization and industrialization. These pollutants are subsequently deposited on many substrates including plant surfaces. Due to their toxicity, mutagenicity, carcinogenicity and recalcitrant nature, they can result in many hazardous effects on human health. Application of endophytes in bioremediation has shown much promise in removing these PAHs from contaminated substrates. In the present study, an attempt was made to isolate and identify endophytic fungi from the moss plant Macromitrium sp. （frequently available） in Sapugaskanda （highly polluted） and HettimuUa （less polluted） areas in Sri Lanka. Subsequently, their potential in degrading PAHs （naphthalene and phenanthrene） was investigated. Endophytes from the moss were isolated following the surface sterilization method, and their physiological roles in degrading naphthalene and phenanthrene were carried out using plate assays, spectrophotometric and high-performance liquid chromatography （HPLC） analysis. Most of the endophytie fungi isolated from Macromitrium sp. were able to grow in Bacto Bushnell-Haas （BBH） medium incorporated with naphthalene and phenanthrene, separately, displaying colony diameters more than 30 mm. As per the results obtained from spectrophotometric and HPLC analysis, Penicillium oxalicum, Nigrospora oryzae, Aspergillus oryzae, A. aculeatus, Penicillium sp.1, Penicillium sp.5, Eupenicillium sp.2 and Mortierella sp.1 degraded both naphthalene and phenanthrene more than 85%. The fmdings of the present investigation provide some insight into how these endophytic fungi could be used for bioremediation of PAHs in environmental sites where contamination prevails, and also open avenues for future research in the relevant field.

本文报道一种新型咪唑键合相的制备,并将这种键合相同氨基键合相（YWG-NH2）的正相色谱性质进行比较,结果表明:咪唑键合相对于分离多环芳烃异构体具有更高的色谱选择性。另外,由于咪唑分子的络合特性和在固定相表面形成螯合物结构,咪唑键合相对Cu（Ⅱ）有更强的络合能力。咪唑-Cu（Ⅱ）键合相可用于高效配体交换色谱中解决芳胺异构体及其类似物的分离。
