Impact of Mild Field Drought on the Aroma Profile and Metabolic Pathways of Fresh Tea () Leaves Using HS-GC-IMS and HS-SPME-GC-MS.

Aroma plays a pivotal role in defining tea quality and distinctiveness, and tea producers have often observed that specific drought conditions are closely associated with the formation and accumulation of characteristic aroma compounds in tea leaves. However, there is still limited understanding of the differential strategies employed by various tea cultivars in response to drought stress for the accumulation of key volatile aroma compounds in fresh tea leaves, as well as the associated metabolic pathways involved in aroma formation. In this study, two widely cultivated tea cultivars in China, Fuding Dabai (FD) and Wuniuzao (WNZ), were examined to assess the impact of mild field drought stress on the composition and accumulation of key volatile aroma compounds in fresh leaves using headspace gas chromatography-ion mobility spectrometry (HS-GC-IMS) and headspace solid phase micro-extraction gas chromatography-mass spectrometry (HS-SPME-GC-MS) technologies.

Fungal community remediate quartz tailings soil under plant combined with urban sludge treatments.

Introduction: Tailings can cause extensive damage to soil structure and microbial community. Phytoremediation is an effective strategy for remedied tailings soil due to its environmentally friendly and low-cost advantage. Fungi play a crucial role in nutrient cycling, stress resistance, stabilizing soil structure, and promoting plant growth.

[Integration of innovation & entrepreneurship concept with the teaching practice of biochemistry experiment].

Biochemistry experiment is an experimental module associated with biochemistry curriculum. In the context of deepening the education reform on innovation & entrepreneurship, integrating the concept of innovation & entrepreneurship with the experimental course is an effective way for the biology discipline to foster professional talents with strong engineering ability and innovation & entrepreneurship ability. Outcome-based education (OBE) is a new concept for education.

[Reform and implementation of technical English course for brewing engineering undergraduates based on STEAM theory].

Technical English is a compulsory course for brewing engineering undergraduates. To improve the quality and effectiveness of teaching, we introduced science, technology, engineering, arts and mathematics (abbreviated to STEAM) education theory in technical English teaching of brewing engineering students, and selected, designed, integrated and optimized the teaching contents. With the help of the Rain Classroom, Massive Open Online Courses of Tsinghua University (XuetangX), Open Language, Wine Folly, training courses of Wine and Spirit Education Trust (WSET) and other platform resources, teaching methods, assessment ways and multi-element teaching evaluation system have been innovatively reformed.

[Control effect and bacteriostasis of mulberry endophytic bacterium Burkholderia cepacia Lu10-1 on silkworm septicemia].

A laboratory test was conducted to study the control effect and bacteriostasis of antagonistic bacterium Burkholderia cepacia Lu10-1 isolated from mulberry on silkworm septicemia, aimed to develop a new microbial pesticide to control silkworm diseases. The supernatant of Lu10-1 zymotic fluid achieved 41.2% control efficiency and 24.
