Reduced cadmium(Cd) accumulation in lettuce plants by applying KMnO modified water hyacinth biochar.

In this study, water hyacinth was adopted to prepare biochar followed by modification using KMnO. And the modified biochars were applied in Cd contaminated soil, exploring the effects of water hyacinth biochar on lettuce growth, Cd enrichment, soil enzyme activities and microbial changes by pot experiments. Modified biochar application significantly reduced the Cd accumulation in lettuce shoots and roots.

Immobilizing partial denitrification biomass and redox mediators to integrate with the anammox process for nitrogen removal.

In this study, immobilizing partial denitrification biomass and redox mediators to integrate with the anammox process for nitrogen removal was investigated. Three redox mediators (RMs), namely, 2-methyl-1,4-naphthoquinone (ME), anthraquinone (AQ) and 1-dichloroanthraquinone (1-AQ) were catalyzed to reduce nitrate to only nitrite by denitrification to integrate with the anammox process for nitrogen removal. First, our experimental results showed that there were 35.

Integrating anammox with the autotrophic denitrification process via electrochemistry technology.

In this study, an autotrophic denitrification process was successfully coupled with anammox to remove the nitrate by-product via electrochemical technology. When the voltage applied to the combined electrode reactor was 1.5 V, the electrode reaction removed nitrate by using the autotrophic denitrification biomass without affecting the anammox biomass.

Depside α-glucosidase inhibitors from a culture of the mushroom Stereum hirsutum.

Nine new isoprenylated depsides, sterenins E-M (1-9), as well as five known compounds (10-14), were isolated from the solid culture of Stereum hirsutum. The structures of the new compounds were elucidated by spectroscopic methods. Their inhibitory activities against yeast α-glucosidase were evaluated in vitro.
