you can begin to find info on these gm versions of the bt soil virus by searching on google. if you put in 'engineered bt virus' you get brittish telecom for a bit but then after you scratch deeper below the surface a range of products emerge. i hAve found brief mention of the engineered bt virus in use in water treatment aswell.
the bt soil virus is an integral part of natural organic and permaculture farming and understanding. it is not clear if the engineered virus would appear on the same order list as a traditionl strain or wether there is any labeling at 'point of sale'. i recently notice that an artist was proccessed under some local state law, for a minor infringement of public safety concepts(sf,ca,usa,04). i think that this could represent a much larger issue. and attract a more in depth analysis. i will post this info in more detail when i have got it together and is appropriate.
