The present invention relates to different recombinant E. coli cells comprising at least a nucleotide sequence corresponding to a structure of GV protein of a gas bladder or a variant of this sequence retaining the capacity for synthesis of said protein GV . These recombinant cells permit the expression of said nucleotide sequence under conditions to improve the flotation properties of transformed cells. The invention also relates to a recombinant vector containing the sequences above and a cell processing method.
