TLDR
The universal method to detect and determine siderophores was developed by using their high affinity for iron(III) and was successfully used to screen mutants in the iron uptake system of two Rhizobium meliloti strains, DM5 and 1021.About:

Siderophores: Structure and Function of Microbial Iron Transport Compounds
TL;DR: Overproduction of the siderophore and its transport system at low iron is in this species well established to be the result of negative transcriptional repression, but the detailed mechanism may be positive in other organisms.

Screening of free-living rhizospheric bacteria for their multiple plant growth promoting activities
TL;DR: On the basis of multiple plant growth promoting activities, eleven bacterial isolates were evaluated for their quantitative IAA production, and broad-spectrum antifungal activity on Muller-Hinton medium against Aspergillus, one or more species of Fusarium and Rhizoctonia bataticola.

Methods for isolating and characterizing ACC deaminase-containing plant growth-promoting rhizobacteria.
TL;DR: A rapid procedure for the isolation of ACC deaminase-containing bacteria, a root elongation assay for evaluating the effects of selected bacteria on root growth, and a method of assessing bacterial ACC deamination activity are described in detail to allow researchers to readily isolate new PGPR strains adapted to specific environments.

TL;DR: Phylogenetic analysis of 16S rRNA gene sequences recovered from one of the libraries indicates that the BAC libraries contain DNA from a wide diversity of microbial phyla, including sequences from diverse taxa such as the low-G+C, gram-positive Acidobacterium,Cytophagales, and Proteobacteria.

TL;DR: The results indicate that G. lucidum and its high molecular weight polysaccharides may be used as prebiotic agents to prevent gut dysbiosis and obesity-related metabolic disorders in obese individuals.

Regulation of ferric iron transport in Escherichia coli K12: isolation of a constitutive mutant.
TL;DR: It was found that transport of ferric enterochelin and ferrichrome was also constitutive in the fur mutant cells, and that ferric citrate uptake could be induced by only 10 μM citrate in the growth medium in contrast to wild-type cells in which at least 100 μMcitrate was necessary.

A Critical Evaluation of the Nitrogen Assimilation Tests Commonly Used in the Classification of Yeasts
TL;DR: The ability of some groups of closely related yeasts to use potassium nitrate as a source of nitrogen was applied successfully by Stelling-Dekker (1931) and later, Lodder added other nitrogen compounds, namely, ammonium sulfate, urea, asparagine, and peptone, in diagnostic tests for her classification of the nonsporogenous, nonfilamentous yeasts.
