In Vivo and in Vitro Conversion of Teasterone to Typhasterol in Cultured Cells of Marchantia polymorpha
Identification by full-scan GC-MS revealed that [2H6]teasterone fed to suspension cultured cells of Marchantia polymorpha was converted to [ 2H6]3-dehydroteasterone and [2H6]typhasterol. This… Expand

Studies on the Microbial Population and the Amylase Activity of the Forest Soil
Soil condition, total number of bacteria, soil amylase activity and microbial biomass were measured at soil of different forest types. And the difference of the allelopathic effect was determined… Expand
Effects of simulated acid rain on microbial activities and litter decomposition
We assayed the effects of simulated acid rain on the mass loss, CO2 evolution, dehydrogenase activity, and microbial biomass-C of decomposing Sorbus alnifolia leaf litter at the microcosm. The dilute… Expand
