Anticoagulant activity was examined by activated partial thromboplastin time assay, and the activatedprotein C-specific amidolytic activity was examined with chromogenic peptide substrate (Pefachrome? PCa). After scre...
Acarboseproducing strainswereinitially pretreated with UVlight andmutated by high doseof maltose to screen the high-production strain which could resist the catabolite repression. The productivity of mutant M-20 incre...
