Production and characterization of biosurfactant producing actinobacteria Streptomyces sp. AS1: a sustainable approach for crude oil degradation.
Article in Brazilian journal of microbiology : [publication of the Brazilian Society for Microbiology], 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Environmental pollution caused by crude oil contamination poses a major ecological threat, highlighting the need for sustainable bioremediation approaches. Biosurfactants produced by actinobacteria offer promising advantages due to their eco-friendly and multifunctional properties. In this study, soil samples were collected from oil contaminated sites in and around Salem, Tamil Nadu, India. Eight morphologically distinct isolates were screened based on β-hemolysis, oil displacement, emulsification index, and lipase activity. Among them, strain AS1 demonstrated the highest biosurfactant activity. Molecular identification through 16 S rRNA gene sequencing confirmed that AS1 belongs to the genus Streptomyces and submitted to GenBank with an accession number-MT525319. The potent strain exhibited strong crude oil degradation capabilities, achieving 95.9% degradation after 168 h as determined by hydrocarbon utilization tests, DCPIP assay, and gravimetric analysis. The biosurfactant extracted from strain AS1 showed notable antibacterial activity against Staphylococcus aureus, Bacillus subtilis, and Escherichia coli, with low minimum inhibitory concentrations, and demonstrated considerable antioxidant potential with 70.04% DPPH radical scavenging activity at 500 µg/ml. Purification by dialysis yielded a partially purified biosurfactant that was characterized by TLC, FT-IR, and GC-MS analyses. FT-IR spectra revealed the presence of functional groups such as alkanes and carboxylic acids, while GC-MS identified several bioactive compounds, including 1-tetradecanol and phthalic acid derivatives. These findings suggest that Streptomyces sp. AS1 strain is a promising candidate for crude oil bioremediation and the development of biosurfactant based applications in pharmaceutical and environmental industries.
