Abstract

Although much is known about the bacterial cellulosome and its various protein components, their contributions to bacterial growth on cellulose and the process of cellulolysis in vivo cannot currently be assessed. To remedy this, the authors have developed gene transfer techniques for Clostridium cellulolyticum ATCC 35319. Firstly, transfer of Tn1545 has been obtained using an Enterococcus faecalis donor. Secondly, IncP-mediated conjugative mobilization of plasmids from Escherichia coli donors has also been achieved. The yield of transconjugants in both cases was low and was probably limited by the suboptimal growth conditions that must of necessity be employed for the co-culture of oligotrophic C. cellulolyticum with copiotrophic donors. A restriction endonuclease was detected in crude extracts of C. cellulolyticum. This enzyme, named CCE:I, is an isoschizomer of MSP:I (HPA:II). Electro-transformation was employed to establish plasmids containing the replication functions of pAMss1 (En. faecalis), pIM13 (Bacillus subtilis), pCB102 (Clostridium butyricum), pIP404 (Clostridium perfringens) and pWV01 (Lactococcus lactis subsp. cremoris) in C. cellulolyticum. Transformants were only obtained if the DNA was appropriately methylated on the external C of the sequence 5'-CCGG-3' using either BSU:FI methylase in vivo or MSP:I methylase in vitro. Plasmids based on the pAMss1 and pIM13 replicons were more stably maintained than one based on the pCB102 replicon. Selection of transformants on solid medium led to low apparent transformation efficiencies (approx. 10(2) transformants per microg DNA) which might, in part, reflect the low plating efficiency of the organism. Selection of transformants in liquid medium led to a higher apparent yield of transformants (between 10(5) and 10(7) transformants per microg DNA). The methods developed here will pave the way for functional analysis of the various cellulosome components in vivo.

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.
