  • Clostridium bifermentans DNA fragment bearing genes coding for proteins linked to an insecticidal activity
    Patent number: 5830722
    Abstract: A nucleotide sequence having the following properties: it includes all or part of DNA fragment XbaI of 7 kb shown in FIG. 4A, as obtained from plasmid pCBM1 filed with the CNCM on Jun. 15, 1993 under no. I-1317; it hybridises with oligonucleotide probe 18A (TGT GAA GTI AAT TGT GA) SEQ ID NO:1 and/or oligonucleotide probe 16A (TTT CAT ATI GAA GCI GTI AAT GAA GG) SEQ ID NO:2 and/or at least one of probes 66A (ATG AAT ACI AAT ATI TTT TCI ACI AA) SEQ ID NO:3 or 66B (TC IGG TTC ICC ATA IAT CCA TTC ATC) SEQ ID NO:4 under stringent conditions; and it codes for a protein, polypeptide or peptide capable of participating in the toxic activity of the expression products of fragment XbaI of 7 kb against Diptera larvae and mosquito or sandfly larvae in particular. The polypeptides encoded by said sequence and their use in larvicidal compositions are also disclosed.
