Nitrogen-fixing bacteria associated with leguminous and non-leguminous plants
TLDR
A wide diversity of nitrogen-fixing bacterial species belonging to most phyla of the Bacteria domain have the capacity to colonize the rhizosphere and to interact with plants.Abstract:
Nitrogen is generally considered one of the major limiting nutrients in plant growth. The biological process responsible for reduction of molecular nitrogen into ammonia is referred to as nitrogen fixation. A wide diversity of nitrogen-fixing bacterial species belonging to most phyla of the Bacteria domain have the capacity to colonize the rhizosphere and to interact with plants. Leguminous and actinorhizal plants can obtain their nitrogen by association with rhizobia or Frankia via differentiation on their respective host plants of a specialized organ, the root nodule. Other symbiotic associations involve heterocystous cyanobacteria, while increasing numbers of nitrogen-fixing species have been identified as colonizing the root surface and, in some cases, the root interior of a variety of cereal crops and pasture grasses. Basic and advanced aspects of these associations are covered in this review.read more

Impact Assessment of Arbuscular Mycorrhiza Azospirillum and Chemical Fertilizer Application on Soil Health and Ecology
TL;DR: The study found that coinoculated plots built up greater soil fertility and SOC, and soil microbial load, and enzymes declined drastically with the increasing percentages of RDF.

TL;DR: In this paper , the relationship between the microbiome and metabolome in the rhizosphere of tea (Camellia sinensis) plants, the bacterial composition and its correlation to soil metabolites were investigated under three different fertilization treatments (unfertilized, urea, cow manure) in different growing seasons (spring, early and late summer).

Indices to identify and quantify ecosystem services in sustainable food systems
TL;DR: In this paper, the authors outline the indicators and indices which can be used to identify and quantify ecosystem services in sustainable food systems options, and strictly follow the Common International Classification of Ecosystem Services to ensure consistency and comparability.

Nitrogen supplemented by symbiotic Rhizobium stimulates fatty-acid oxidation in Chlorella variabilis
TL;DR: It is indicated that bacterial fixed nitrogen reduces lipid accumulation in microalgae, which is not beneficial for biodiesel production, and further studies on the effects of other bacteria on micro algae are needed to assess most optimal practices for biod diesel production.

Generic assignments, strain histories, and properties of pure cultures of cyanobacteria
TL;DR: Revisions are designed to permit the generic identification of cultures, often difficult through use of the field-based system of phycological classification, and are both constant and readily determinable in cultured material.

Genetic regulation of biological nitrogen fixation

TL;DR: The ability of microorganisms to use nitrogen gas as the sole nitrogen source and engage in symbioses with host plants confers many ecological advantages, but also incurs physiological penalties because the process is oxygen sensitive and energy dependent.
