“…Enhancement of B-galactosidase production is important in industry. Most of the efforts have been in screening for better b-galactosidase-producing organisms (Mahoney et al 1975;Agrawal et al 1982;Foda 1983;Kowaleski et al 1982;Bailey and Linko 1990). Nevalainen (1981) reported Two loopfuls of the spore suspension of A. nager were transferred from a recent subculture to 50 ml of Potato Dextrose (PD) broth (Himedia, Bombay, India), incubated at 30°C for 72 h. It was then centrifuged aseptically at 13 000 g for 15 min.…”

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 mutant yielded a third generation u.v.-treated strain, UV-5 with a 117.6% increase in beta-galactosidase productivity with respect to the parent strain.
