Mcn. Saparrat et al., Production of ligninolytic enzymes by Fusarium solani strains isolated from different substrata, WORLD J MIC, 16(8-9), 2000, pp. 799-803
A comparative study on the extracellular ligninolytic enzymatic activity of
five strains of Fusarium solani in a carbon-limited medium under shaking,
revealed a differential production of these enzymes. Aryl alcohol oxidase (
AAO) activity was observed only in the supernatant of strain CLPS no. 568 w
ith levels higher than 57 mU ml(-1) Free extracellular laccase activity was
detected in strains CLPS nos. 493, 568 and 570, strain no. 568 being the o
ne which showed the highest activity (over 8.6 mU ml(-1)). Free extracellul
ar lignin peroxidase (LiP) activity was not detected in any isolate tested,
whereas low levels of manganese-dependent peroxidase (MnP) and manganese-i
ndependent peroxidase (MIP) activities were detected in certain isolates us
ed. The AAO activity of F. solani on primary alpha -alcohols such as veratr
yl alcohol, is reported for the first time; this enzyme activity is hydroge
n-peroxide independent. This is also the first report for extracellular MnP
and MIP activities of F. solani.
