Effects of lipidic carbon sources on the extracellular lipolytic activity of a newly isolated strain of Bacillus subtilis.
Article in Journal of industrial microbiology & biotechnology, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
An isolate exhibiting high extracellular lipolytic activity was identified as Bacillus subtilis by 16S rRNA gene sequence analysis. The enzyme activity of the isolate was improved by using different concentrations of lipidic carbon sources such as vegetable oils, fatty acids and triglycerides. Lipolytic activity was assayed spectrophotometrically using p-nitrophenyl palmitate. One percent (v/v) of sesame oil provided the highest activity with 80 and 98% enhancements with respect to 1% (v/v) concentrations of linoleic acid and triolein as the favored fatty acid and triglyceride, respectively. Glucose presented a repressive effect on lipase production. Lipase secreted by B. subtilis was partially purified by ultrafiltration and anion exchange chromatography; and the purified enzyme was tested for its residual activity in the presence of EDTA, SDS, Triton X-100, Tween 20, Tween 80 and protease. The present work reports, for the first time, that the lipolytic activity of a B. subtilis strain can be improved by using inexpensive vegetable oils; and also that B. subtilis lipase is suitable for use in detergents.
