Abstract
Novel methods and novel industrial unicellular microorganism strains, particularly industrial Bacillus strains, are provided for enhanced production of endogenous and exogenous polypeptides. Cloning vehicles containing the gene expressing the polypeptide of interest are introduced into a compatible host. Transformed hosts harboring the introduced vehicle in a stable way by integration of the vehicle into the host cells chromosome are selected. Efficient transfer of the vehicle containing the gene of interest is achieved, with the resulting industrial strain transformants being effective, stable producers of the desired polypeptide product.
