Diazotrophs are bacteria and archaea that can reduce atmospheric dinitrogen (N 2) into
ammonium. Plant–diazotroph interactions have been explored for over a century as a …

The contribution of biological nitrogen fixation to the total N requirement of food and feed
crops diminished in importance with the advent of synthetic N fertilizers, which fueled the …

Paenibacillus is a large genus of Gram-positive, facultative anaerobic, endospore-forming
bacteria. The genus Paenibacillus currently comprises more than 150 named species …

Globally, agriculture depends on industrial nitrogen fertilizer to improve crop growth.
Fertilizer production consumes fossil fuels and contributes to environmental nitrogen …

Cucumber is an important vegetable crop in China. Fusarium wilt is a soil-borne disease that
can significantly reduce cucumber yields. Paenibacillus polymyxa WLY78 can strongly …

Riboflavin, an essential vitamin for animals, is used widely in the pharmaceutical industry
and as a food and feed additive. The microbial synthesis of riboflavin requires a large …

How bacteria sense and respond to nitrogen levels are central questions in microbial
physiology. In Gram-positive bacteria, nitrogen homeostasis is controlled by an operon …

Most diazotrophs fix nitrogen only under nitrogen-limiting conditions, for example, in the
presence of relatively low concentrations of NH4+ (0 to 2 mM). However, Paenibacillus …

Diazotrophic bacteria can reduce N2 into plant-available ammonium (NH4+), promoting
plant growth and reducing nitrogen (N) fertilizer requirements. However, there are few …

Synthetic regulation of metabolic fluxes has emerged as a common strategy to improve the
performance of microbial cell factories. The present regulatory toolboxes predominantly rely …
