Isolation and characterization of alkane hydroxylases from a metagenomic library of Pacific deep-sea sediment.

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
Two clones 9E7 and 21G8 in a metagenomic library of the east Pacific deep-sea sediment were found to contain alkane hydroxylase genes (alkB). The whole insert sequences of the two cosmid clones were determined. The insert sequences of 9E7 and 21G8 are 40 and 35 kb, respectively. Besides alkB, several alcohol/aldehyde dehydrogenase genes were also determined. A homolog of rubredoxin 2 of Pseudomonas putida was identified on 9E7 immediately downstream the alkB gene, but was lacking on 21G8. Unlike previous reports, the alkB genes on 9E7 and 21G8 have opposite transcription directions to those of linked alcohol/aldehyde dehydrogenase genes. Phylogenetic analysis put these two deep-sea AlkBs into a unique branch of integral membrane hydroxylases. The two alkB genes (9E7-alkB and 21G8-alkB) were cloned into pCom8 and introduced into two alkB expression host systems P. fluorescens KOB2 Delta 1 and P. putida GPo12 (pGEc47 Delta B). The transformed strains can grow on the n-alkanes from C5 to C16, indicating that both 9E7-AlkB and 21G8-AlkB have a wide substrate range. The data further indicate that the deep sea would be a rich resource for exploring novel alkane-degrading strains and genes.
