Characterisation of microbial Mat communities in meltwater ponds of the McMurdo ice shelf, Antarctica
… secondary metabolite production. Using 16S rRNA gene and morphological analysis a large diversity of cyanobacteria (more than 22 phylotypes) was identified with high phylogenetic similarities (up to 99% sequence identity) to cyanobacteria from mats in other regions of Antarctica. In addition …

Evaluation of Nitrogenase Genes as Markers in Soil Microbial Community Studies
… for specific target sequences, i.e., the nifH gene, for both uncultured nitrogen-fixing members of the ɛ-subdivision of Proteobacteria and cultured and uncultured frankiae, and baseline data that demonstrated the usefulness of the molecular tools for studies on the ecology of both …

Diversity of Free-living Nitrogen Fixing Bacteria in the Badlands of South Dakota
… (NMF) under hypoxic conditions. The 16srRNA and nifH genes were amplified and sequenced. This was complemented using a culture independent approach, amplifying nifH from soil DNA extracts. The 16S rRNA gene data indicated a diversity of putative free-living diazotrophs across 4 phyla …

Characterization of the nifUHD cluster and a new myoglobin-like gene from Nostoc commune UTEX 584
… determined the exact locations of the <i>nifU, nifH</i>, and <i>nifD</i> genes and identified two potential stem loop structures, a direct repeat, and an ORF that codes for a protein with a predicted amino acid sequence similar to that of myoglobin from <i>Paramecium caudatum</i>. The <i>N. …

Legume integration and nutrient management impacts on soil health and cropping system productivity
… soil and cowpea nodules were assessed using nifH gene abundance. Full-length 16S rRNA sequencing was also used to profile rhizosphere bacterial communities. Cowpea growth was greatest in the urea and medium C:N treatments. Cowpea grown under the medium C:N fixed the highest amount of N, …

Diversity and distribution of Tylosema esculentum (Marama bean) endophytic bacteria communities in Omitara, Harnas and Otjinene, eastern Namibia
… isolates (605) were identified, grouped into 24 genera and three phyla. Proteobacteria was the most represented (67.4%) followed by Firmicutes (23.7%) and Actinobacteria (4.3%). Shannon diversity index, revealed a significant difference between the tuberous roots and leaves (p = 0.005) and stems …

Bioaugmentation and biostimulation of a South African coal-based Technosol as a mine rehabilitation strategy
… vegetation and inoculation, abundances of nirK gene encoding nitrite reductase denitrification enzymes were augmented in Technosols fabricated with higher dosages of MR, suggesting enhanced nitrogen uptake. Vegetation in inoculated Technosols amended with 5 wt.% MR assisted remediation of soil …
