Abstract excerpt

A series of mutations was carried out with Aspergillus niger NCIM-616 as the parent strain. A mutant strain NG-4 with 28% increased beta-galactosidase productivity was produced with N-methyl-N-nitro-N-nitrosoguanidine (NTG) at 1500 micrograms ml-1 concentration and exposure time of 60 min. This m...
