Abstract
The metabolites of the genus Marasmius are diverse, showing good research prospects for finding new bioactive molecules. In order to explore the active metabolites of the fungi Marasmius berteroi, the deep chemical investigation on the bioactive compounds from its cultures was undertaken, which led to the isolation of three new naphthalene compounds dipolynaphthalenes A-B (1,2) and naphthone C (3), as well as 12 known compounds (4-15). Compounds 1, 2, and 4 are dimeric naphthalene compounds. Their structures were elucidated by MS, 1D and 2D NMR spectroscopic data, as well as ECD calculations. Compounds 2-4 and 7 exhibited acetylcholinesterase (AChE) inhibitory activities at the concentration of 50 μg/mL with inhibition ratios of 42.74%, 44.63%, 39.50% and 51.49%, respectively. Compounds 5 and 7,8 showed weak inhibitory activities towards two tumor cell lines, with IC50 of 0.10, 0.076 and 0.058 mM (K562) and 0.13, 0.18, and 0.15 mM (SGC-7901), respectively.

Abstract
Gongga Mountain or Minya Konka, like the Himalayan Dimension Mountains, has its own microclimate and a 'circum-polar' climate and hence is sensitive to contamination by persistent pollutants that are trapped by cold temperature and wet precipitation. Elemental mercury (Hg) as vapour easy diffuses into the atmosphere and the rate of Hg deposition from global fallout is dependent on locally ambient temperature and precipitation. We investigated the accumulation and distribution of total Hg in two species of mushrooms, Gymnopus erythropus and Marasmius dryophilus, which grew on Gongga Mountain. The fruiting bodies were collected at a height of 2946m above see level. Both species efficiently accumulated Hg. The median values for caps of M. dryophilus and G. erythropus were 1.168 and 3.078, and for stipes 0.573 and 1.636mg/kg dry matter, respectively, and in the beneath litter and soil were 0.13 and 0.15mg/kg dry matter. The Hg contents of the caps of M. dryophilus and the beneath litter and soils from pristine Himalayan forest of 1.168, 0.132 and 0.116mg/kg dry matter (respectively) is high compared to values reported for similar species and soils from background areas in Poland -0.58-0.70 and 0.047-0.048mg/kg dry matter. The absence of industrial activities, urbanization and Hg ore deposits at Gongga Mountain suggests that long-range atmospheric transport and subsequent deposition is the major source of elevated Hg observed in the mushrooms, litter and surface layer of soils in the outskirts of Gongga Mountain maritime glacier that has a peak of 7556m above sea level.

Abstract
We investigated the potential of the laccase from the white-rot fungus Marasmius quercophilus to transform certain alkylphenols (p-nonylphenol, p-octylphenol and p-t-octylphenol). We tested the reactivity of this enzyme under different conditions: in liquid cultures and using the partially purified laccase with and without 2,2'-azino-bis-3-ehtylbenzothiazoline-6-sulfonicacid (ABTS) as a mediator. The percentage of p-t-octylphenol disappearance in liquid cultures was 69.0 ± 1.5% and 81 ± 5% after a 8-d or 15-d incubation, respectively, with p-nonylphenol, these percentages were 62 ± 4% and 91 ± 6% and with p-octylphenol 37 ± 3% and 65 ± 1% after a 15-d and a 21-d incubations, respectively. Induced pre-cultures were also used to inoculate the liquid cultures to enhance p-octylphenol transformation: the percentages of disappearance were 91.0 ± 0.5% and 97 ± 1% after a 8-d and a 15-d incubation, respectively. Mass spectrometry analysis showed that the products of oxidation of p-octylphenol were dimers with a mass of 411 m/z. Furthermore, we identified a purple compound (m/z 476) formed when ABTS was added to the reaction medium with the purified laccase. This result confirms that, in complex environments such as soils or litters where many molecules can interact with the enzyme substrate or the product of oxidation, laccase activities and those of other phenoloxidases should not be measured with ABTS.
