1 · What the graph read from it

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.

2 · The registry

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

Production of esters from the acetone-butanol-ethanol (ABE) fermentation by Clostridium often focuses on butyl butyrate, leaving acetone as an undesired product. Addition of butyrate is also often needed because ABE fermentation does not produce enough butyrate. Here we addressed the problems using Clostridium beijerinckii BGS1 that preferred to produce isopropanol instead of acetone, and co-culturing it with Clostridium tyrobutyricum ATCC 25,755 that produced butyrate. Unlike acetone, isopropanol could be converted into ester using lipase and acids. C. tyrobutyricum ATCC 25,755 produced acids at pH 6, while C. beijerinckii BGS1 produced mainly solvents at the same pH. When the two strains were co-cultured, more butyrate was produced, leading to a higher titer of esters than the mono-culture of C. beijerinckii BGS1. As the first study reporting the production of isopropyl butyrate from the Clostridium fermentation, this study highlighted the potential use of lipase and co-culture strategy in ester production.
