Elucidating the Functional and Taxonomic Diversity of Soil Microbial Communities From Three Commercial Soybean Farms in South Africa

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Prior to inoculation of soybeans, South African soils contain no Bradyhizobia that nodulate and fix nitrogen in soybeans. Soybean cultivation with prolonged inoculation resulted in the establishment and dominance of Bradyrhizobia in three soybean farms in South Africa as revealed by a microbial community study using shotgun metagenomics. ABSTRACT Prior

Characterization of a nifH-Harboring Bacterial Community in the Soil-Limited Gotjawal Forest [PDF]

Frontiers in Microbiology, 2019
Using a high-throughput metagenomic approach, we evaluated nifH-harboring bacterial communities and their assembly in the Gotjawal forest, which was naturally formed on basalt rocks with thin layer of soil. Significant differences in soil properties and community structure were observed in comparison with similar communities in various habitats ...

A ‘Genome‐First’ Framework for Next‐Generation Bioinputs: From Functional Mining to Rational Synthetic Microbial Communities

Environmental Microbiology, Volume 28, Issue 5, May 2026.
I propose a ‘genome‐first’ framework to collapse the phenotypic bottleneck in bioinput discovery. By integrating multi‐layered genome mining and reverse ecology, this paradigm enables the rational design of stable synthetic microbial communities for a data‐driven and sustainable agricultural bioeconomy.

Design and application of an oligonucleotide microarray (nifH-phylochip) for nifH gene-based detection of nitrogen-fixing prokaryotes

, 2005
Biological nitrogen fixation, the enzymatic reduction of N:sub:2:/sub: to ammonium, is anexclusively prokaryotic process which is crucial to balance the global nitrogen cycle.The key enzyme of this process -- nitrogenase -- has been highly conserved ...

Diversity of nifH gene amplified from plankton-community DNA in a shallow eutrophic lake (Lake Donghu, Wuhan, China)

, 2011
Biological nitrogen fixation (BNF) is one of the major nitrogen inputs into the biosphere, and the nitrogenase iron protein (nifH) gene plays important roles in regulating the molecular nitrogen (N-2) fixation process.

Diversity and expression of nitrogenase genes (nifH) from ectomycorrhizas of Corsican pine (Pinus nigra)

, 2006
The diversity of bacterial nitrogenase genes (nifH) and their mRNA transcription in ectomycorrhizas of Corsican pine (Pinus nigra) were examined. DNA and RNA were extracted from surface-sterilized and non-sterilized Corsican pine roots colonized by the ...

UNDERSTANDING THE NIFM DEPENDENCE OF NIFH IN AZOTOBACTER VINELANDII:FUNCTIONAL SUBSTITUTION OF NIFH BY A NIFH-CHLL CHIMERIC CONSTRUCT IN A NIFM- STRAIN

, 2007
The enzyme nitrogenase catalyzes the energy-dependent reduction of dinitrogen to ammonia via biological nitrogen fixation. Nitrogenase is composed of two metalloproteins known as the molybdenum-iron (MoFe) protein and the iron (Fe) protein.

Microvirga lupini sp. nov., Microvirga lotononidis sp. nov., and Microvirga zambiensis sp. nov. are Alphaproteobacterial root nodule bacteria that specifically nodulate and fix nitrogen with geographically and taxonomically separate legume hosts

, 2012
Strains of Gram-negative, rod-shaped, non-spore-forming bacteria were isolated from nitrogen-fixing nodules of the native legumes Listia angolensis (from Zambia) and Lupinus texensis (from Texas, USA).
