Tightly regulated expression vectors for Ochrobactrum anthropi.

abstract：:In the present work, Aspergillus fumigatus is described as a higher producer of hydrolytic enzymes secreted in response to the presence of the Callosobruchus maculatus bruchid pest. This fungus was able to grow over cowpea weevil shells as a unique carbon source, secreting alkaline proteolytic and chitinolytic enzymes...
