The Phytoplankton of the Huguangyan Maar Lake

Seasonal variability in concentrations and fluxes of glycerol dialkyl glycerol tetraethers in Huguangyan Maar Lake, SE China: Implications for the applicability of the MBT–CBT paleotemperature proxy in lacustrine settings

“…Thaumarchaeota are nitrifiers (Könneke et al, 2005;Leininger et al, 2006) and tend to live close to areas where ammonium is released, which is consistent with the inferred physiology of Thaumarchaeota (Könneke et al, 2005;Leininger et al, 2006). It was found that ammonium released from the bottom sediment is an important replenishment of N in HML (Zhang et al, 2008).…”

“…2) (Wang et al, 2008(Wang et al, , 2012. Hence, during periods of strong wind, turbulence in the water column breaks down the thermal stratification in the lake, causing nutrient-rich bottom water to mix with surface water (Pilskaln and Johnson, 1991;Zhang et al, 2008). These conditions favor algal productivity (especially diatoms) in HML (Zhang et al, 2008), which might result in an increase in the total mass flux (Fig.…”

“…during periods of strong winds, turbulence in the water column breaks down the thermal stratification in the lake, causing nutrient-rich bottom water to mix with surface water (Pilskaln and Johnson, 1991;Zhang et al, 2008). These conditions favor the growth of algae (especially diatoms) in the upper layers (Zhang et al, 2008) and also the productivity of bacteria that produce branched GDGT in HML (Fig. 3b).…”

Identification and Cytotoxic Activities of Two New Trichothecenes and a New Cuparane-Type Sesquiterpenoid from the Cultures of the Mushroom Engleromyces goetzii

“…The positive curative effects of E. goetzii have garnered interest regarding the chemical constituents of this mushroom. Previous investigations on the fruiting bodies of this fungus have led to the isolation of neoengleromycin, cytochalasin D and 19,20-epoxycytochalasin D [4,6,7]. However, the chemical constituents of the cultures of this fungus have not been previously reported.…”

“…This fungus typically grows on bamboo in high mountains, and it ripens during the rainy season from July to August. Local residents can purchase this fungus at the market and boil the fruiting bodies in water to treat infection, inflammation and cancer [3][4][5]. The positive curative effects of E. goetzii have garnered interest regarding the chemical constituents of this mushroom.…”
