A new plasmid, pNQ116, was constructed in Bacillus sphaericus by cloning a promoter fragment from B. sphaericus Ts-1 into pNQ112. The plasmid (CmrKmr, 5.23 kb) contains a restriction endonuclease polylinker used for cloning foreign genes, and its cat-86 gene is expressed at high levels from the Ts-1 promoter. This plasmid vector has been transformed into B. sphaericus AS 1.270, AS 1.465, AS 1.469, and 2362, at frequencies of 10(2)-10(3) transformants per microgram of DNA, and is maintained stably under nonselective conditions in these host strains. The presence of pNQ116 in B. sphaericus 2362 does ot interfere with the mosquito larvicidal activity of the organism.
