A dna fragment of 348 - bp amplified from the b subunit gene was cut into two dna fragment of 216 and 132 - bp by haelli. endonuclease restriction analysis of the plasmid content with psti showed that strainas with the same result of southern - blot with spesific probe had the different cleavage pattern. the isolated 285 - bpand 348 - bp dna was ligated with plasmid puc18. the ligation mixture was used to transform e. coli jm109and the transformants were plated on lb agar containing antibiotics. plasmid dna containing cloned genes were used for direct sequencing
