“…Many RNases have been reported to occur in fungi such as Aspergillus niger (1), A. oryzae (RNases Tl and T2) (2, 3), A. saitoi (RNase M) (4), Aspergillus species (RNase L) (5,6), Neurospora crassa (RNases N,, N2 and N3) (7,8), Ustilago sphaerogena (RNases U1, U2, U3 and U4) (9,10), Rhizopus species (RNase R) (11) and so on. However, few studies have been reported on the changes in RNase activity in relation to fungal growth.…”
