Antimicrobial compounds produced by Lysinibacillus odysseyi epiphytic bacteria associated with red algae.
Article in Brazilian journal of microbiology : [publication of the Brazilian Society for Microbiology], 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
Seaweed epiphytic bacteria are highly host specific and their association is little known. The marine environment of Andaman Islands is rich in algal diversity and their association with microbial communities remains unexplored. We investigated the epiphytic bacterial communities from the intertidal red alga Gracilaria canaliculata. A total of four epiphytic bacterial isolates were cultured and screened for antimicrobial activity. Of the four isolates, one potential isolate, Gr102, exhibited strong antimicrobial activity in 0.50 μg/ml concentration against enteropathogenic Escherichia coli, Klebsiella pneumoniae, and Shigella flexneri. This potential isolate was characterized by genomic sequencing, fatty acid methyl ester analysis, and matrix-assisted laser desorption ionization-time of flight spectrometry, and the strain Gr102 was identified as Lysinibacillus odysseyi KC149512. Purified fractions obtained were analyzed by gas chromatography and mass spectrometry. Antimicrobial compounds such as furan, lupenol, diazene, and butenyl methyl ketone were identified. Based on the high level of activity, red algae epiphytic bacteria are potential sources of producing bioactive secondary metabolites.
