The members of the Bacillus thuringiensis group, commonly known as Bt, produce a huge number of metabolites, which show biocidal and antagonistic activity. B. thuringiensis is widely known for synthesizing Cry, Vip and Cyt proteins, active against insects and other parasporins with biocidal activity against certain types of cancerous cells. Nevertheless, B. thuringiensis also synthesizes compou...
Ocneria terebinthina Strg. (Lep.: Lymanteriidae) is a leaf borer pest in pistachio orchard. The toxicity of Bacillus thuringiensis var. kurstaki alone and in combination with henna powder was investigated on third larval instar of O. terebinthina under laboratory conditions. Bioassay was carried out using spray technique on pistachio offshoot. Probit analysis of concentration-mortality data was...
Bacillus thuringiensis is widely used in producing ecofriendly microbial agents for the purpose of controlling insect pests. In this study, we determined the complete genome sequence of B. thuringiensis subsp. jinghongiensis reference strain YGd22-03, which contains three cry genes and one cerecidin biosynthetic gene cluster.
A fluorescent heteroduplex method was developed to assess the presence of 16S rRNA gene (rDNA) sequences from Bacillus anthracis and close relatives in PCR-amplified 16S rDNA sequence mixtures from environmental samples. The method uses a single-stranded, fluorescent DNA probe, 464 nucleotides in length, derived from a B. anthracis 16S rRNA gene. The probe contains a unique, engineered deletion...
Levels, genetic traits and stability of resistance to Bacillus thuringiensis of the Bang Bua Tong (BS) population of the diamondback moth Plutella xylostella collected in Thailand were investigated. The BS population exhibited 668 and 66.5-fold resistance to formulations derived from B. thuringiensis subsp. kurstaki (Toarow CT®), and B. thuringiensis subsp. aizawai (XenTari®), respectively. In ...
The strain 273 B, the type strain of a H serotype of Bacillus thuringiensis not yet characterized: B. thuringiensis subsp. cameroun, serotype H32, was isolated from soil samples collected in Cameroon. This strain produces cuboidal parasporal bodies composed of two major proteins of 53 kDa and 35 kDa. N-terminal sequences of the major proteins share no homology with published sequences. Only the...
We were able to isolate Bacillus thuringiensis from environmental samples with a background of 10 bacteria per g of soil. Our selection process differed significantly from classical selection methods which permit only the desired organism to grow. In our process, germination of B. thuringiensis spores was selectively inhibited by sodium acetate, while most of the undesired sporeformers germinat...
objective: in this study the efficacy of two agent of this biological control agent of corn stem borer in corn fields compared with common synthetic insecticides endosolfan to find a suitable alternative for chemical control of pests in corn fields. methods: in order to evaluate the efficiency of biocontrol agents of corn stem borer ,ostrinia nubilalis, experiment was conducted in a randomized ...
