Background Bacillus thuringiensis is a Gram-positive, spore-forming bacterium that belongs to the B.cereus group along with Bacillus anthracis and Bacillus cereus. Bacillus thuringiensis is an insect pathogen that is widely used as a biopesticide in commercial agriculture due to its various endogenous crystal proteins and spores. When insects ingest toxin crystals, the alkaline pH of their digestive tract activates the toxin. Cry inserts into the insect gut cell membrane, forming a pore. The pore results cell lysis and eventual death of the insect.B.thuringiensis is not amenable to genetic engineering due to its thick cell wall layer, which along with the natural presence of many plasmids reduces its transformation efficiency. Strain BMB171 is a laboratory derivative of wild-type crystalliferous strain YBT- 1463. It has a high transformation efficiency and has only 1 plasmid. While it no longer encodes crystal protein genes it is able to produce these proteins upon transformation with appropriate plasmids (adapted from PMID 20525827 and Wikipedia). (HAMAP: BACT1)
