Turnover-Dependent Inactivation of the Nitrogenase MoFe-Protein at High pH [PDF]
, 2014 Proton uptake accompanies the reduction of all known substrates by nitrogenase. As a consequence, a higher pH should limit the availability of protons as a substrate essential for turnover, thereby increasing the proportion of more highly reduced forms ...

Advancements in Alginate‐Based Biomaterials for Enhanced Skin Regeneration: A Comprehensive Review
International Journal of Polymer Science, Volume 2026, Issue 1, 2026.Alginate, a naturally occurring polysaccharide composed of β‐d‐mannuronate (M) and α‐l‐guluronate (G), has attracted widespread attention for skin regeneration applications due to its exceptional biocompatibility, biodegradability, and tunable physicochemical properties. Beyond its traditional role in maintaining a moist wound environment and providing

The Siderophore Metabolome of Azotobacter vinelandii [PDF]
Applied and Environmental Microbiology, 2016 ABSTRACT In this study, we performed a detailed characterization of the siderophore metabolome, or “chelome,” of the agriculturally important and widely studied model organism Azotobacter vinelandii . Using a new high-resolution liquid chromatography-mass spectrometry (LC-MS) approach, we found over 35 ...

Journal of Plant Nutrition and Soil Science, Volume 188, Issue 6, Page 861-872, December 2025.ABSTRACT Background Selenium (Se) plays a vital role as a beneficial element in promoting the production of leguminous plants. It influences legume quality by improving crop nutritive value and contributing to human and animal health. Literature Review This review is timely, as there are gaps in understanding Se–rhizobia interactions in legumes, which ...
