This paper reports the isolation and draft genome sequencing of Azotobacter sp. strain CWF10 from lateritic agricultural soil in Madhya Pradesh, India, producing a 5.7 Mb genome in 14 contigs with 65.09% G+C content. Genomic comparisons using average nucleotide identity and digital DNA–DNA hybridization indicate it may represent a potential novel species, and the genome contains many plant growth-promoting genes, including those linked to nitrogen availability, folic acid biosynthesis, and siderophore systems such as vibrioferrin and crochelin A involved in iron uptake. The main caveat is that the work is confined to genomic mining and does not present experimental validation of these functional capacities. The paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

Abstract

Azotobacter sp. strain CWF10, an aerobic gram negative, oval shaped and motile bacterium, was isolated from a lateritic agricultural soil of Madhya Pradesh, India. The draft genome of the isolate is 5.7 Mb in size, consisting of 14 contigs with 65.09 % G+C content. Average nucleotide identity (94.66%) and digital DNA-DNA hybridization (62%) calculation with closest reference strains underpin the bacterium as a potential novel species. The bacterium has a plethora of plant growth promoting genes that point towards potential ability for enhancement of available nitrogen, biosynthesis of folic acid, among others. Siderophores such as vibrioferrin and crochelin A are also present in the genome which are known to regulate iron uptake. Overall, mining of the genome of Azotobacter sp. strain CWF10 has revealed the potential of this strain for application in regenerative agriculture and sustaining soil health.
