Abstract: The present invention discloses a selection marker free system which can be used to introduce genetic modifications in bacteria, yeasts and fungi. The system can be employed to introduce or delete desired genes or DNA fragments in the genome of the indicated host species without leaving any undesired DNA i.e. the selection marker used for selection of transformants or other DNA used for cloning. In this way strains have been developed containing only desired genes introduced at desired chromosomal sites. Similarly, desired DNA fragments have been deleted or replaced at desired sites.

It is operated by measuring an insufflation pressure at the upstream end of the insufflation path, continuously calculating intracavity pressure from the insufflation pressure by evaluating loss of pressure of the flow path, comparing the calculated intracavity pressure and a preset value of this intracavity pressure, and controlling the flow-control valve as a function of the result of the comparison with the above-mentioned preset value in order to continuously supply a flow of the neutral gas that is minimally sufficient to compensate for leakage of gas from the surgical cavity and to maintain the intracavity pressure generally equal to the preset value.
