Improving the Efficiency of a Bioreactor Equipped With Mixed‐Flow Impellers

Chemical Engineering &Technology, Volume 48, Issue 7, July 2025.
The present work investigated the biological performance of mixed‐flow impellers. To the authors’ knowledge, this is the first experimental study on such impellers in a fermentation process using A. vinelandii, which was chosen as a microorganism due to its high oxygen demand.

Role of LEAFLESS, an AP2/ERF family transcription factor, in the regulation of trichome specialized metabolism

New Phytologist, Volume 247, Issue 2, Page 774-790, July 2025.
Summary Acylsugars, specialized metabolites produced by trichomes of many solanaceous species, provide protection against biotic and abiotic stresses. Many acylsugar metabolic enzymes have been identified; however, regulatory factors remain unknown.

Fructan biosynthesis gene expression upon cold acclimation in orchardgrass (Dactylis glomerata L.)

Grassland Research, Volume 4, Issue 2, Page 121-130, June 2025.
Orchardgrass genes involved in fructan biosynthesis and metabolism split into the four major groups as part of the large GH32 gene family. Within the fructosyltransferase group, two genes were induced upon cold stress and are homologous to 1‐SST and 6‐SFT. Abstract Background Fructan content and flux in temperate forages can benefit the grasses through

PtrVINV2 is dispensable for cellulose synthesis but essential for salt tolerance in Populus trichocarpa Torr. and Gray

Plant Biotechnology Journal, Volume 23, Issue 6, Page 1892-1908, June 2025.
Summary Invertase (EC.3.2.1.26), a key enzyme in sucrose breakdown, is crucial for cellulose synthesis. However, the function of the vacuolar invertase (VINV) in woody plants remains unclear. In this study, transgenic lines of Populus trichocarpa Torr. and Gray were generated to investigate the role of PtrVINV2 in wood formation and under high salinity

Analysis of carbohydrates and glycoconjugates by matrix‐assisted laser desorption/ionization mass spectrometry: An update for 2021–2022

Mass Spectrometry Reviews, Volume 44, Issue 3, Page 213-453, May/June 2025.
Abstract The use of matrix‐assisted laser desorption/ionization (MALDI) mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this review is the 12th update of the original article published in 1999 and brings coverage of the literature to the end of 2022.

Transfructosylation of Rebaudioside A (a Sweet Glycoside of Stevia Leaves) with Microbacterium .BETA.-Fructofuranosidase.

Chemical and Pharmaceutical Bulletin, 1991
It was found that a beta-fructofuranosidase produced by Microbacterium sp. H-1 has potent trans-beta-fructofuranosylation activity from sucrose (donor). By means of this enzyme system, rebaudioside A (RA), the second major sweet steviol glycoside of the leaves of Stevia rebaudiana, was subjected to transfructosylation, affording a mono-beta ...

Soil Microbial Population And Soil Enzyme Activity On Various Reclamation Area Of PT Bukit Asam In South Sumatera [PDF]

, 2018
Open mining activities result in a decrease in microbial biomass and a negative impact on soil fertility. Soil microbes play a role in the decomposition of soil organic matter and nutrient cycles through the process of mineralization by the enzyme they ...

Non‐Additive Gene Expression in Carbon and Nitrogen Metabolism Drives Growth Heterosis in Populus deltoides

Plant, Cell &Environment, Volume 48, Issue 5, Page 3529-3543, May 2025.
ABSTRACT Growth heterosis is crucial for Populus deltoides breeding, a key industrial‐timber and ecological‐construction tree species in temperate regions. However, the molecular mechanisms underlying carbon (C)–nitrogen (N) metabolism coordination in regulating growth heterosis remain unclear. Herein high‐hybrids of P.

Carbon source dependent promoters in yeasts [PDF]

, 2014
Budding yeasts are important expression hosts for the production of recombinant proteins. The choice of the right promoter is a crucial point for efficient gene expression, as most regulations take place at the transcriptional level.
