Abstract

Tn1545, a conjugative transposon originally discovered in Streptococcus pneumoniae, has been transferred from Enterococcus faecalis and Bacillus subtilis to Clostridium acetobutylicum NCIB 8052. Transfer between different strains of C. acetobutylicum has also been observed. Insertion of Tn1545 into the C. acetobutylicum chromosome occurred at multiple sites, as shown by Southern hybridization. Although ermAM (erythromycin-resistance) was the most satisfactory marker for primary selection of transconjugants, all three Tn1545-encoded antibiotic resistance genes (aphA-3, ermAM, and tetM) were apparently expressed in C. acetobutylicum. Our results indicate that Tn1545 is potentially useful for undertaking mutagenesis and mutational cloning in this industrially important organism. Transfer of another conjugative transposon, Tn916, from E. faecalis to C. acetobutylicum NCIB 8052 was also apparently detected. Circumstantial evidence suggests that there may be a hot spot for Tn916 insertion in the C. acetobutylicum NCIB 8052 chromosome.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Earlier efforts of transposon mutagenesis were demonstrated in C. saccharobutylicum, C. acetobutylicum, and C. beijerinckii, but issues with multiple transposon insertions per mutant and non-random distribution of insertions were reported.

    “Earlier efforts of transposon mutagenesis were demonstrated in C. saccharobutylicum (Keis et al., 2001), C. acetobutylicum, and C. beijerinckii, but issues with multiple transposon insertions per mutant, and non-random distribution of insertions were also reported (Bertram and Dürre, 1989; Woolley et al., 1989).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
