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

Bacteriophage contamination and cell lysis have been recurring issues with some actinomycetes used in the pharmaceutical fermentation industry since the commercialization of streptomycin in the 1940s. In the early years, spontaneous phage-resistant mutants or lysogens were isolated to address the problem. In some cases, multiple phages were isolated from different contaminated fermentors, so strains resistant to multiple phages were isolated to stabilize the fermentation processes. With the advent of recombinant DNA technology, the early scaleup of the Escherichia coli fermentation process for the production of human insulin A and B chains encountered contamination with multiple coliphages. A genetic engineering solution was to clone and express a potent restriction/modification system in the production strains. Very recently, an E. coli fermentation of 1,3-propanediol was contaminated by a coliphage related to T1. CRISPR/Cas9 technology was applied to block future contamination by targeting seven different phage genes for double-strand cleavage. These approaches employing spontaneous mutation, genetic engineering, and synthetic biology can be applied to many current and future microorganisms used in the biotechnology industry.
