Thuricin: the bacteriocin produced by Bacillus thuringiensis.
It exhibited a bactericidal and bacteriolytic effect on a sensitive strain, B. thuringiensis serovar, canadensis (MF4), and partially purified preparations of thuricin had phospholipase A activity which was adsorbed by sensitive cells but not by cells which were insensitive to thURicin. Expand
Transfer of Bacillus lentimorbus and Bacillus popilliae to the genus Paenibacillus with emended descriptions of Paenibacillus lentimorbus comb. nov. and Paenibacillus popilliae comb. nov.
The results obtained by using different tree algorithms, bootstrap analysis, branch lengths and verification by signature nucleotide analysis supported the reclassification of these species in the genus Paenibacillus as PaenIBacillus lentimorbus comb. Expand
Ultrastructural Analysis of Spores and Parasporal Crystals Formed by Bacillus sphaericus 2297.
The development of spores in the bacterial cells was accompanied by the formation of parasporal crystals, which may be a source of the mosquito larval toxin in this strain of B. sphaericus, but proof will require their isolation from other cellular components. Expand
Toxic activity of Bacillus sphaericus SSII-1 for mosquito larvae.
Using larvae of the mosquito Culex pipiens var. quinquefasciatus as a bioassay system, we have verified an earlier proposal that pathogenicity of Bacillus sphaericus SSII-1 is a toxin-mediated ratherExpand
Deoxyribonucleic Acid Homologies Among Strains of Bacillus sphaericus
None of the physiological characteristics or combination of characteristics examined allowed the complete differentiation of strains into the appropriate homology groups, and the strains of group I could be distinguished from those of group IIA-IIB. Expand

Cloning and sequencing of the gene encoding a 125-kilodalton surface-layer protein from Bacillus sphaericus 2362 and of a related cryptic gene.
Using the vector pGEM-4-blue, a 4,251-base-pair DNA fragment containing the gene for the surface (S)-layer protein of Bacillus sphaericus 2362 was cloned into Escherichia coli. Determination of theExpand
Bacillus popilliae and Bacillus lentimorbus, bacteria causing milky disease in Japanese beetles and related scarab larvae
Growth in media supplemented with 2% NaCI was found to be a somewhat less reliable characteristic in distinguishing the species than vancomycin resistance, the latter being present only in B. popilliae. Expand
Batch and continuous culture production of the mosquito larval toxin ofBacillus sphaericus 2362
Batch and continuous culture were used to investigate the production of Bacillus sphaericus mosquito larvicide and toxin yield in continuous culture was too low to be a likely alternative to batch culture. Expand
Localization of a mosquito-larval toxin of Bacillus sphaericus 1593.
Cell-free wall, membrane, and cytoplasmic fractions were prepared from Bacillus sphaericus 1593, which exhibited toxic activity against larvae of the mosquito Culex pipiens var. quinquefasciatus.Expand
