What are the environmental biotech companies (not public culture collections) that could sell/purchase microorganisms with special biodegradative capacities?
You did not say what special bugs you are looking for. They are not Biotech companies but microbial strain collections, also selling such bugs: The ATCC in the USA, the DSMZ in Germany, and a few others. Both of them have special catalogues on their web pages.
Tahar Mechichi , there exists many companies which can sell microorganisms capable to degrade various pollutants. Our compamy can do that.
According to my opinion you should specifyx, which pollutants should be degraded and according this requirement look after companies capable to supply the most suitable degraders.
