A novel method for rapid determination of eight lipophilic pesticides in vegetables was developed using dispersive liquid-liquid micro-extraction (DLLME) coupled with gas chromatography-tandem mass spectrometry (GC-MS/MS). The analyte in the vegetable was extracted with water-acetone (5 : 1, v/v) solution. Then, the extract was transferred into a(More)
Bacillus thuringiensis (Bt) strain FJAT-12 was a novel Bt strain isolated by Agricultural Bio-Resources Institute, Fujian Academy of Agricultural Science. In this study, a new cry2Ab gene was cloned from Bt strain FJAT-12 and named as cry2Ab30 by Bt delta-endotoxin Nomenclature Committee. The sequencing results showed there were two mutations in(More)
OBJECTIVE The present work reported the isolation, identification and diversity of Bacillus species colonizing on the surface and endophyte in lichens collected from Wuyi Mountain. METHODS Nine lichen samples of Evernia, Stereocaulon, Menegazzia and other 6 genera belonging to 7 families were collected from Wuyi mountain nature reserve. The bacillus-like(More)
Brevibacillus choshinensis HPD52(T) (DSM 8552) is a Gram-positive, spore-forming, and protein-producing bacterium. Here, we report the 6.28-Mb draft genome sequence of B. choshinensis HPD52(T), which will promote its application and provide useful information for genomic taxonomy and phylogenomics of Bacillus-like bacteria.
