Taxonomic and functional characteristics of aerobic bacteria isolated from the chloragogenous tissue of the earthworm Aporrectodea molleri.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Earthworms are considered as a rich microhabitat for the growth and proliferation of diverse soil microorganisms. Hence, earthworms' associated bacteria attracted interest due to their high metabolic profiles and benefits to soil fertility and plant growth. In this study, we aimed to isolate for the first-time aerobic bacteria present in the chloragogenous tissue of the earthworm Apporectodea molleri and test their Plant Growth-Promoting abilities and their resistance to heavy metals (Mn, Zn, Cu, Cd, and Ni). The 16S rRNA gene sequencing revealed the affiliation of the fifteen isolates to six main bacterial genera: Enterobacter, Citrobacter, Aeromonas, Pseudomonas, Bacillus, Terribacillus. These strains displayed different plant growth promoting traits (e.g., indole-3-acetic acid IAA, siderophores, nitrogen fixation, phosphate, and potassium solubilization), in addition, they were able to resist differently to heavy metals. Bacillus strains were most effective as three strains, namely B. subtilis strain TC34; B. circulans strain TC7 and Bacillus sp. strain TC10, were positive to all PGP traits and resisted to all heavy metals. This study illustrates the potential of bacteria from the chloragogenous tissue to exhibit multiple properties, which can be related to the functional feature of this tissue to stock metabolites and neutralize toxic elements.
