Response mechanism of ethanol-tolerant Saccharomyces cerevisiae strain ES-42 to increased ethanol during continuous ethanol fermentation.

Background: Continuous fermentation offers advantages in improving production efficiency and reducing costs, making it highly competitive for industrial ethanol production. A key requirement for Saccharomyces cerevisiae strains used in this process is their tolerance to high ethanol concentrations, which enables them to adapt to continuous fermentation conditions. To explore how yeast cells respond to varying levels of ethanol stress during fermentation, a two-month continuous fermentation was conducted.

Background: Study the leaf functional traits is highly important for understanding the survival strategies and climate adaptability of old trees. In this study, the old (over 100 years old) and mature trees (about 50 years old) of Pinus tabulaeformis in the Loess Plateau were studied, and the variation of 18 leaf functional traits (6 economic, 4 anatomical, 2 photosynthetic and 6 physiological traits) was analyzed to understand the differences of survival strategies between old and mature trees. Combined with transcriptome and simple sequence repeats (SSR) techniques, the effects of soil property factors and genetic factors on leaf functional traits and the potential molecular mechanisms of traits differences were studied.

Changes in structural composition of field margins and related landscape homogenization following EU accession of Poland.

Department of Botany, University of Wrocław, Kanonia 6/8, 50-328, Wrocław, Poland.
Field margins have considerable ecological significance in farming landscapes, but are subject to constant changes resulting from natural processes and anthropogenic pressures. Understanding the balance of these processes is important from an ecological and conservation perspective. We measured 20 variables related to margin composition, woody vegetation and adjacent cropland fragmentation in 70 field margins in SW Poland in 2004 and 2006 (Poland's accession to the EU), and then resurveyed in 2021 by using the same protocol.
