Trichloroethylene (TCE) poses a potentially toxic threat to humans and the environment and widely exists in contaminated sites. White rot fungi effectively degrade refractory pollutants, while a few research studies use white rot fungi to degrade TCE. In this study, we investigated TCE biodegradation by white rot fungi and the potential influencing factors in the environment and attempted to research the effect of TCE on the physiological characteristics of white rot fungi. White rot fungi (Trametes versicolor, Pseudotrametes gibbosa, Pycnoporus sanguines and Pleurotus ostreatus) were added to the liquid medium for shock culture. The results revealed that T. versicolor exhibited the most pronounced efficacy in removing TCE, with a degradation rate of 81.10% within a 7 d period. TCE induces and is degraded by cytochrome P450 enzymes. High pH and Cr(VI) adversely affected the effectiveness of the biodegradation of TCE, but the salinity range of 0-1% had less effect on biodegradation. Overall, the effectiveness of degradation of TCE by T. versicolor has been demonstrated, and it provides a reference for the application prospects of white rot fungi in TCE-contaminated soils.

A key feature of extant conifer forests is the high percentage of seeds that germinate and establish on dead wood; in some forests, this can exceed 90%. This deadwood can act as an ideal nursery for young tree species, leading to this type of seedbed being termed 'nurse logs'. It is unclear how common this ecological strategy has been throughout the evolutionary history of conifers.

The function of fermented and non fermented bamboo-derived feed additives in poultry nutrition is critically assessed in this review, with emphasis on the effects on growth performance, immunity, intestinal health, egg and meat quality. Fermented bamboo feeds have become a promising nutritional innovation in poultry production. The use of bamboo leaves and tender shoots in chicken feed is limited due to the presence of lignin and cellulose.

Nrg1 is a C2H2 zinc finger transcription factor that functions in various cellular processes related to environmental responses and cell wall synthesis in yeast. The present study investigated the function of Nrg1 in filamentous development in the white-rot fungus Pleurotus ostreatus for the first time. The Δnrg1 strains exhibited a higher frequency and larger angles of hyphal branching than the wild-type strain, suggesting nrg1 is essential to hyphal branching regulation.
