The Loess Plateau region of northwestern China has unique geological and dry/semi-dry climate characteristics. However, knowledge about ectomycorrhizal fungal (EMF) communities in the Loess Plateau is limited. In this study, we investigated EMF communities in Populus simonii and Pinus tabuliformis patches within the forest-steppe zone, in pine forests(More)
Quercus liaotungensis is a major tree species in deciduous broad-leaved forests in northern China. In this study, we investigated ectomycorrhizal (ECM) communities associated with Q. liaotungensis from five typical habitats across northern China. We used internal transcribed spacer-polymerase chain reaction and DNA sequencing to identify ECM fungi, and we(More)
Preliminary studies have shown that the bioassay based on inhibition of alpha-glucosidase biosyn-thesis (AGB) in Bacillus licheniformis is useful in the acute toxicity screening of environmental samples. Alpha-glucosidase is an extracellular enzyme induced by the presence of maltose in the environment of the cell. The enzyme degrades maltose into glucose(More)
