Thermostable acidic protease production in Aspergillus terreus NCFT 4269.10 using chickling vetch peels
A newly isolated fungus, Aspergillus terreus NCFT4269.10, was employed in both solid state (SSF) and liquid static surface culture (LSSC) for the production of protease using different agro-residues. Among different substrates appraised, chickling vetch peels (CVP) supported the enhanced production...
